Pin Functions

PIN I/O(1) DESCRIPTION
NAME NO.
ASC 1 I Active high to enable active short circuit function to force output high during system failure events
OC 2 I Over current detection pin, support lower threshold for SenseFET, DESAT, and Shunt resistor sensing
COM 3 P Common ground reference, connecting to emitter pin for IGBT and source pin for SiC-MOSFET
OUTH 4 O Gate driver output pull up
VDD 5 P Positive supply rail for gate drive voltage, Bypassing a >220nF capacitor to COM to support specified gate driver source peak current capability
OUTL 6 O Gate driver output pull down
CLMPE 7 O External Active miller clamp, connecting this pin to the gate of the external miller clamp MOSFET
VEE 8 P Negative supply rail for gate drive voltage. Bypassing a >220nF capacitor to COM to support specified gate driver sink peak current capability
GND 9 P Input power supply and logic ground reference
IN+ 10 I Non-inverting gate driver control input
IN– 11 I Inverting gate driver control input
RDY 12 O Power good for VCC-GND and VDD-COM. RDY is open drain configuration and can be paralleled with other RDY signals
FLT 13 O Active low fault alarm output upon over current or short circuit. FLT is in open drain configuration and can be paralleled with other faults
RST/EN 14 I The RST/EN serves two purposes:
1) Enable / shutdown of the output side. The FET is turned off by a general turn-off, if terminal EN is set to low;
2) Resets the OC condition signaled on FLT pin. if terminal RST/EN is set to low for more than 1000ns. A reset of signal FLT is asserted at the rising edge of terminal RST/EN.
For automatic RESET function, this pin only serves as an EN pin. Enable / shutdown of the output side. The FET is turned off by a general turn-off, if terminal EN is set to low.
VCC 15 P Input power supply from 3V to 5.5V, bypassing a >100nF capacitor to GND
APWM 16 O Isolated PWM output monitoring ASC pin status
