PD16804
MONOLITHIC H BRIDGE DRIVER CIRCUIT
DESCRIPTION
The
µ
PD16804 is a monolithic H bridge driver IC which uses low-ON resistance power MOS FETs in its driver stage.
This driver has a forward, reverse, and brake functions and is ideal for the driver circuit of motors for camera that
advance or rewind the film, and auto focusing or zooming.
This IC supports a drive current of up to 0.5 A (DC).
FEATURES
