TIMING DIAGRAM
1. Input Interlock Timing Diagram
When the input signals (HIN/LIN) are high at the same time, the output (HOUT/LOUT) will maintain previous status. But if the input signals
(HIN/LIN) go high simultaneously, HIN signals would be active and cause HOUT to enter into high status.
The M81019FP matches delay between the low side and high side driver allowing minimized dead time control for better speed range and
torque control in motor drive applications.

2. Input/Output Timing Diagram
When overcurrent is detected, CIN will be tripped if LIN is high; then the short circuit protection will activate and shut down the outputs
and FO will indicate fault by going low. As soon as FO_RST is driven high, short circuit protection will deactivate and FO goes high.
The output will then respond to any subsequent active input signal.

DEAD-TIME
NOTE 1: Input pulse width should be set to more than
200ns for HIN/LIN input filter circuit.
NOTE 2: If high-high status of input signals HIN/LIN
completes with one input signal in low level and the
other in high level, the output will enter into high-low
status without dead time.
NOTE 3: This diagram does not show delay time
between input and output.
NOTE 1: This diagram does not show delay time

4. FO Input Timing Diagram
When FO is pulled low by an enternal signal, the output will be shut down. As soon as FO goes high again, the output will respond to the
next active input signal.
When VCC supply voltage is lower than power reset trip voltage, the power reset trips and output is locked out. As soon as VCC supply
voltage does higher than power reset trip voltage, the output will respond to the next active input signal.

When VBS supply voltage goes lower than VBS supply UV trip voltage for a period than the VBS supply UV filter time, HOUT goes low
regardles of HIN. As soon as VBS supply voltage goes higher than VBS supply reset voltage, the output will respond to the next active
HIN signal.

NOTE 1: This diagram does not show delay time

NOTE 2: At power supply start-up it is recommended
that dVBS/dt should be controlled to avoid H latch of

7. Power Start-Up Sequence
At power supply start-up the following sequence is recommended when bootstrap supply topology is used.
Output configuration is shown in the following figure. At turn-off an n-channel NMOS with sink current up to 1A is used to offer a low
impedance path (AKA “low impedance NMOS) to prevent the power switch from turning itself on because of the parasitic Miller
capacitor in the power switch.

8. Low Impedance NMOS Output Timing Diagram
When HIN/LIN is low level and VOUT voltage is lower than low impedance NMOS input threshold voltage, the low impedance NMOS
continues to discharge the parasitic current through Cres.
1. Set VCC.
2. Make sure FO is in high level.
3. Set LIN to high level and set HIN to low
level so that bootstrap capacitor will
charge.
4. Set LIN to low level.
NOTE: If two power supplies are used to supply VCC
and VBS individually, it is recommended to set VCC
first, then set VBS.
