Guaranteed to be in the correct state for VCC higher than +1.0V, these devices are ideal for multiple-voltage systems with strict monitoring requirements. Secondary VCC Supervisory Range: +0.9 to +2.5V (AS1913/ AS1914/AS1915) User-Adjustable Threshold Down to +0.63V (AS1910/AS1911/ AS1912) Guaranteed Reset Valid Down to VCC = +1.0V The AS1913/AS1914/AS1915 feature factory-trimmed thresholds to monitor a primary voltage between 1.8 and 3.6V, and a secondary voltage between 0.9 and 2.5V. Reset Timeout Delay: 215ms Manual Reset Input Three Reset Output Types: For the AS1910/AS1911/AS1912, a secondary monitoring voltage can be user-adjusted via an external resistor divider down to 0.6V. The devices are available with the reset output types listed in Table 1. - Active-High Push/Pull - Active-Low Push/Pull - Active-Low Open-Drain Table 1.

Additionally, these devices feature a watchdog timer to help ensure that the processor is operating within proper code boundaries. 3 Applications The devices are ideal for portable and battery-powered systems, embedded controllers, intelligent instruments, automotive systems, critical CPU monitoring, and any multi-supply application. The AS1910 - AS1915 are available in a 6-pin SOT23 package. Figure 1.

Pin Descriptions Pin Number Pin Name Description RESETN Active-Low Reset Output (AS1910, AS1912, AS1913, AS1915). The RESETN signal toggles from high to low when VCC, VCC2, or RESETIN input drops below the factory-trimmed reset threshold (see Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a reset. This output signal remains low for the reset timeout period after all supervised voltages exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset. RESET Active-High Reset Output (AS1911, AS1914). The RESET signal toggles from low to high when VCC, VCC2, or RESETIN input drops below the factory-trimmed reset threshold (see Table 4 on page 4), or MRN is pulled low, or the watchdog triggers a reset. This output signal remains high for the reset timeout period (see tRP on page 5) after all supervised voltages exceed their reset threshold, or MRN goes low to high, or the watchdog triggers a reset. 1 2 3 4 GND Ground MRN Active-Low Manual Reset Input. Pulling this pin low asserts a reset. This pin is connected to the internal 50k pullup to VCC. This reset remains active as long as MRN is low and for the reset timeout period (see tRP on page 5) after MRN goes high. Note: If the manual reset feature is not used, this pin should be unconnected or connected to VCC. WDI Watchdog Input. If WDI remains high or low for longer than the watchdog timeout period (see tWD on page 6), the internal watchdog timer period expires and a reset is triggered for the reset timeout period (see tRP on page 5). The internal watchdog timer clears whenever a reset is a asserted or when WDI senses a rising or falling edge. Note: To disable the watchdog feature, this pin must be unconnected or connected to a tri-state buffer output. WDI must be low or unconnected (tristate) during the reset timeout period tRP, (see Figure 13 on page 10). RESETIN User-Adjustable Supervised Voltage Input (AS1910/AS1911/AS1912). This high-impedance pin serves as the input to the internal reset comparator. Connect this pin to an external resistor-divider network to set the reset threshold voltage (down to 0.63V). 5 6 VCC2 Primary Supervised Voltage Input (AS1913/AS1914/AS1915).

The integrated watchdog timer (see Watchdog Input on page 10) helps mitigate against bad programming code or clock signals, and/or poor peripheral response. An active-low manual reset input (see Manual Reset Input on page 10) allows for an externally activated system reset. 8.1 RESET/RESETN Whenever one of the monitored voltages falls below its reset threshold, the RESET output (AS1910, AS1912, AS1913, AS1915) asserts low or the RESETN output (AS1911, AS1914) asserts high. Once all monitored voltages have stabilized, an internal timer keeps the reset asserted for the reset timeout period (tRP). After the tRP period, the RESET or RESETN output return to their original state (see Figure 10). Figure 9.

The threshold voltage for RESETIN is between 0.61 and 0.65V (0.63 typ). Figure 12. Voltage Monitoring Circuit VMONITOR R1 5 R2 AS1910/AS1911/ AS1912 RESETIN VCC VRESETIN To monitor a voltage higher than 0.63V, connect a resistor divider network to the circuit as shown in Figure 12. For the circuit shown in Figure 12, the threshold at VMONITOR is: VMONITOR_TRIP = 0.63V [(R1 + R2)/R2] (EQ 1) Note: Since RESETIN is powered by VCC, VRESETIN must not be larger than VCC. www.austriamicrosystems.com/Supervisors/AS1910 Revision 1.03 9 - 16 AS1910 - AS1915 Datasheet - D e t a i l e d D e s c r i p t i o n 8.3 Watchdog Input The integrated watchdog feature can be used to monitor processor activity via pin WDI, and can detect pulses as short as 50ns. The watchdog requires that the processor toggle the watchdog logic input at regular intervals, within a specified minimum timeout period (1.5s, typ). A reset is asserted for the reset timeout period. As long as reset is asserted, the timer remains cleared and is not incremented. When reset is deasserted, the watchdog timer starts counting (Figure 11). Note: The watchdog timer can be cleared with a reset pulse or by toggling WDI. Figure 13. Watchdog Timing Relationship VCC RESETN tRST tRP tWD tRP WDI The RESET signal is the inverse of the RESETN signal. The watchdog is internally driven low during most (87.5%) of the watchdog timeout period (see tWD on page 6) and high for the rest of the watchdog timeout period. When pin WDI is left unconnected, this internal driver clears the watchdog timer every 1.4s. When WDI is tri-stated or is not connected, the maximum allowable leakage current is 10A and the maximum allowable load capacitance is 200pF. Note: The watchdog function can be disabled by leaving pin WDI unconnected or connecting it to a tri-state output buffer. 8.4 Manual Reset Input The active-low pin MRN is used to force a manual reset. This input can be driven by CMOS logic levels or with open-drain collector outputs. Pulling MRN low asserts a reset which will remain asserted as long as MRN is kept low, and for the timeout period (see tRP on page 5) after MRN goes high (140ms min). The manual reset circuitry has an internal 50k pullup resistor, thus it can be left open if not used. To create a manual-reset circuit, connect a normally open momentary switch from pin MRN to GND (see Figure 1 on page 1); external debounce circuitry is not required in this configuration. If MRN is driven via long cables or the device is used in a noisy environment, a 0.1F capacitor between pin MRN and GND will provide additional noise immunity. www.austriamicrosystems.com/Supervisors/AS1910 Revision 1.03 10 - 16 AS1910 - AS1915 Datasheet - A p p l i c a t i o n I n f o r m a t i o n 9 Application Information 9.1 Watchdog Input Current The watchdog input is driven through an internal buffer and an internal series resistor from the watchdog timer (see Figure 11 on page 9). When pin WDI is left unconnected (watchdog disabled), the watchdog timer is serviced within the watchdog timeout period (see tWD on page 6) by a low-high-low pulse from the counter chain. For minimum watchdog input current (minimum overall power consumption), pull WDI low for most of the watchdog timeout period, pulsing it low-high-low once within the first 7/8 (87.5%) of the watchdog timeout period to reset the watchdog timer. Note: If WDI is externally driven high for the majority of the timeout period, up to 160A can flow into pin WDI. 9.2 Interfacing to Bi-Directional CPU Reset Pins Since the reset outputs of the AS1912 and AS1915 are open drain, these devices interface easily with processors that have bi-directional reset pins. Connecting the processor reset output directly to the AS1912/AS1915 RESETN pin with a single pullup resistor (see Figure 14) allows the AS1912/AS1912 to assert a reset. Figure 14. AS1912 or AS1915 RESETN-to-CPU Bi-Directional Reset Pin VCC VCC 6 VCC 1 CPU RESETN AS1912/ AS1915 RESETN Reset Generator GND GND 2 9.3 Fast Negative-Going Transients Fast, negative-going VCC transients normally do not require the CPU to be shutdown. The AS1910 - AS1915 are virtually immune to such transients. Resets are issued to the CPU during power-up, powerdown, and brownout conditions. Note: VCC transients that go 100mV below the reset threshold and last 55s typically will not assert a reset pulse. 9.4 Valid Reset to VCC = 0 The AS1910 - AS1915 are guaranteed to operate properly down to VCC = 1V. For applications requiring valid reset levels down to VCC = 0, a pulldown resistor to active-low outputs (push/pull only) and a pullup resistor to active-high outputs (push/pull only) will ensure that the reset line is valid during the interval where the reset output can no longer sink or source current. 9.5 Watchdog Tips Careful consideration should be taken when implementing the AS1910 - AS1915 watchdog feature. One method of supervising software code execution is to set/reset the watchdog input at different places in the code, rather than pulsing the watchdog input high-low-high or low-high-low. This method avoids a loop condition in which the watchdog timer would continue to be reset inside the loop, preventing the watchdog from ever timing out. Figure 15 shows a flowchart where the input/output driving the watchdog is set high at the beginning of the routine, set low at the beginning of every subroutine, then set high again when the routine returns to the beginning. If the routine should hang in a subroutine, the problem would quickly be corrected, since the I/O is continually set low and the watchdog timer is allowed to time out, causing a reset or interrupt to be issued (see Watchdog Input Current on page 11). This method results in higher averaged WDI input current over time than a case where WDI is held low for the majority (87.5%) of the timeout period and periodically pulsing it low-high-low. www.austriamicrosystems.com/Supervisors/AS1910 Revision 1.03 11 - 16 AS1910 - AS1915 Datasheet - A p p l i c a t i o n I n f o r m a t i o n Figure 15.
