MONOLITHIC QUAD H-BRIDGE DRIVER CIRCUIT

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.

MOS INTEGRATED CIRCUIT

FEATURES Four H bridge circuits employing power MOSFETs Low current consumption by eliminating charge pump VM pin current when power-OFF: 10 mA MAX. VDD pin current: 10 mA MAX. Input logic frequency: 100 kHz 3-V power supply Minimum operating supply voltage: 2.5 V Low voltage malfunction pr
