Description:

Gauge driver integrated circuit.

PC33991, Gauge Driver Integrated Circuit

H-Bridge Output.

This is the output pin of a half bridge, designed to source or sink current.

The H-Bridge pins linearly drive the sine and cosine coils of two separate stepper motors to provide four-quadrant operation.
