Low side supply voltage
Logic ground
Logic input for low side gate driver outputs (LO1,2,3), in phase
Indicates over-current (ITRIP) or low-side undervoltage lockout has occurred. Negative logic, open-drain
output
Logic input to enable I/O functionality. Positive logic, i.e. I/O logic functions When ENABLE is high. No
effect on FAULT and not latched
Analog input for overcurrent shutdown. When active, ITRIP shuts down outputs and activates FAULT and
RCIN low. When ITRIP becomes inactive, FAULT stays active low for an externally set time T
automatically becomes inactive (open-drain high impedance).
External RC network input used to define FAULT CLEAR delay, T
When RCIN > 8 V, the FAULT pin goes back into open-drain high-impedance
