O Status Output; open collector output, connect to external pull-up resistor
3 GND – 2) Ground
4 REF I Reference Input; connect to shunt resistor
5D
O Status Delay; optional, connect to GND via an optional capacitor to
extend the status reaction time. Leave open, if no delay is required.

I Input; battery supply, connect a decoupling ceramic capacitor of at least
100 nF directly at the IC to ground
9 GND – 2) Exposed Pad; connect to GND in application
1) Please take care of different maximum ratings of I- and PWM-pins during circuit design.
2) Connect all GND-pins together.
