µPD16803
MONOLITHIC DUAL H BRIDGE DRIVER CIRCUIT
DESCRIPTION
The µPD16803 is a monolithic dual H bridge driver circuit which uses N-channel power MOS FETs in its driver stage. By employing the power MOS FETs for the output stage, this driver circuit has a substantially improved saturation voltage and power consumption as pared with conventional driver circuits that use bipolar transistors. In addition, the drive current can be adjusted by an external resistor in a power-saving mode. The µPD16803 is therefore ideal as the driver circuit of the 2-phase excitation, bipolar-driven stepping motor for the head actuator of an FDD.
