TC4426A/TC4427A/TC4428A 1.5A Dual High-Speed Power MOSFET Drivers Features: General Description: * High Peak Output Current - 1.5A * Wide Input Supply Voltage Operating Range: - 4.5V to 18V * High Capacitive Load Drive Capability - 1000 pF in 25 ns (typical) * Short Delay Times - 30 ns (typical) * Matched Rise, Fall and Delay Times * Low Supply Current: - With Logic `1' Input - 1 mA (typical) - With Logic `0' Input - 100 A (typical) * Low Output Impedance - 7(typical) * Latch-Up Protected: Will Withstand 0.5A Reverse Current * Input Will Withstand Negative Inputs Up to 5V * Electrostatic Discharge (ESD) Protected - 2 kV * Pin-compatible with TC426/TC427/TC428 and TC4426/TC4427/TC4428 * Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN-S Packages The TC4426A/TC4427A/TC4428A are improved versions of the earlier TC4426/TC4427/TC4428 family of MOSFET drivers. In addition to matched rise and fall times, the TC4426A/TC4427A/TC4428A devices have matched leading and falling edge propagation delay times. These devices are highly latch-up resistant under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against Electrostatic Discharge (ESD) up to 2 kV. The TC4426A/TC4427A/TC4428A MOSFET drivers can easily charge/discharge 1000 pF gate capacitances in under 30 ns. These devices provide low enough impedances in both the on and off states to ensure the MOSFET's intended state will not be affected, even by large transients.

TABLE 3-1: PIN FUNCTION TABLE (Note 1) Symbol Description PDIP, MSOP, SOIC 6x5 DFN-S 1 1 NC 2 2 IN A Input A 3 3 GND Ground 4 4 IN B Input B 5 5 OUT B 6 6 VDD 7 7 OUT A 8 8 NC No connection 9 EP Exposed Metal Pad -- Note 1: 3.1 Inputs A and B (IN A, IN B) Output A 3.4 Supply Input (VDD) The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 18V, with respect to the ground pin. The VDD input should be bypassed with local ceramic capacitors. The value of these capacitors should be chosen based on the capacitive load that is being driven. Ground (GND) The ground pin is the return path for both the bias current and the high-peak current that discharges the external load capacitance. The ground pin should be tied into a ground plane or have a very short trace to the bias supply source return. 3.3 Output B Supply input Duplicate pins must be connected for proper operation. MOSFET driver inputs A and B are high-impedance, TTL/CMOS compatible inputs. These inputs also have 300 mV of hysteresis between the high and low thresholds that prevents output glitching, even when the rise and fall time of the input signal is very slow. 3.2 No connection 3.5 Exposed Metal Pad (EP) The exposed metal pad of the 6x5 DFN-S package is not internally connected to any potential. Therefore, this pad can be connected to a ground plane or other copper plane on a printed circuit board, to aid in heat removal from the package. Output A and B (OUT A, OUT B) MOSFET driver outputs A and B are low-impedance, CMOS push-pull style outputs. The pull-down and pull-up devices are of equal strength, making the rise and fall times equivalent. DS20001423H-page 8 2002-2013 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: * Microchip products meet the specification contained in their particular Microchip Data Sheet. * Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. * There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. * Microchip is willing to work with the customer who is concerned about the integrity of their code. * Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip's code protection feature may be a violation of the Digital Millennium Copyright Act.
