OUTB2

Power output Power bridge output side B2

OUTB1

Power output Power bridge output side B1

SENSEB2

Power output Sense output of the bridge B

SENSEB1

Power output Sense output of the bridge B

SNSB

Analog input Full bridge B current regulator sense input

STBY\

RESET

Logic input

Standby\Reset input.

When forced low the device enter in low consumption mode

ENA\

FAULTA

Logic input\

open drain

output

Logic input 5 V compliant with open drain output.

This is the full bridge A enable (when low, the power stage is

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

MOSFET when a failure occurs.

This is the full bridge B enable (when low, the power stage is

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

MOSFET when a failure occurs.

PWMA

Logic input

Full bridge A PWM input

PHA

Logic input
