Ground

Device ground

OUTB2

Power output Power bridge output side B2

SENSEB

Power output Sense output of the bridge B

OUTB1

EN\FAULT

Logic input\

open drain

output

Logic input 5 V compliant with open drain output.

This is the power stage enable (when low, the power stage

is turned off) and is forced low through the integrated open

drain MOSFET when a failure occurs.
