Description

Low side gate driver supply

Logic ground

HIN

Logic input for high side gate driver outputs (HOP/HON)

LIN

Logic input for low side gate driver outputs (LOP/LON)

FAULT/SD

Dual function (in/out) active low pin. Refer to Figs. 15, 17, and 18. As an output, indicates fault condition.

SY_FLT

Dual function (in/out) active low pin. Refer to Figs. 15, 17, and 18. As an output, indicates SSD sequence

is occurring. As an input, an active low signal freezes both output status.

FLT_CLR

Fault clear active high input. Clears latched fault condition (see Fig. 17)

LOP

COM

Low side driver return

High side gate driver floating supply

HOP

High side driver sourcing output

HON

High side driver sinking output

DSH

High side IGBT desaturation protection input

SSDH
