DESCRIPTION

By employing the power MOS FETs for the output stage, this driver circuit has a substantially improved saturation voltage

and power consumption as compared with conventional driver circuits that use bipolar transistors.

actuator of an FDD.

FEATURES

• Low ON resistance (sum of ON resistors of top and bottom transistors)

• Low current consumption: I

• Stop mode function that turns OFF all output transistors

• Compact surface mount package: 20-pin plastic SOP (300 mil)

PIN CONFIGURATION (Top View)

The PD16803 is a monolithic dual H bridge driver circuit which uses N-channel power MOS FETs in its driver stage.

In addition, the drive current can be adjusted by an external resistor in a power-saving mode.

The PD16803 is therefore ideal as the driver circuit of the 2-phase excitation, bipolar-driven stepping motor for the head
