MOS INTEGRATED CIRCUIT

µPD16804

MONOLITHIC H BRIDGE DRIVER CIRCUIT

DESCRIPTION

The

µPD16804 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).
