Description

Low side supply voltage

Logic ground

HIN1,2,3

Logic inputs for high side gate driver outputs (HO1,2,3), in phase

LIN1,2,3

Logic input for low side gate driver outputs (LO1,2,3), in phase

FAULT

Indicates over-current (ITRIP) or low-side undervoltage lockout has occurred. Negative logic, open-drain

output

EN

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

ITRIP

Analog input for overcurrent shutdown. When active, ITRIP shuts down outputs and activates FAULT and

automatically becomes inactive (open-drain high impedance).

RCIN

When RCIN > 8 V, the FAULT pin goes back into open-drain high-impedance

COM

Low side gate drivers return

High side floating supply

HO1,2,3

High side gate driver outputs

High voltage floating supply return

LO1,2,3

Low side gate driver outputs
