MOS INTEGRATED CIRCUIT
µPD16877
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. 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. As the package, a 24-pin plastic TSSOP is adopted to enable the creation of compact, slim application sets. This driver IC can drive two stepping motor at the same time, and is ideal for driving stepping motors in the lens of a camcorder.
FEATURES
Four H bridge circuits employing power MOSFETs Low current consumption by eliminating charge pump VM pin current when power-OFF: 10 µA MAX. VDD pin 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))
