DESCRIPTION

The µPD168101 is monolithic quad H-bridge driver LSI which uses power MOSFETs in the output stages. By using the MOS process, this driver IC has substantially improved the voltage loss of the output stage and power consumption as compared with conventional driver circuits using bipolar transistors.

By eliminating the charge pump circuit, the current during power-OFF is drastically decreased.

In addition, a low-voltage malfunction prevention circuit is also provided that prevents the IC from malfunctioning when the supply voltage drops.
