DESCRIPTION

The µPD16877 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 saturation voltage and power consumption as compared with conventional driver circuits using bipolar transistors.

FEATURES

Four H bridge circuits employing power MOSFETs

Low current consumption by eliminating charge pump VMpin current when power-OFF: 10 µA MAX. VDDpin current: 10 µA MAX.

Input logic frequency: 100 kHz

3-V power supply

  Minimum operating supply voltage: 2.5 V

Low voltage malfunction prevention circuit

24-pin plastic TSSOP (5.72 mm (225))
