µPD16837
MONOLITHIC QUAD H BRIDGE DRIVER
DESCRIPTION
The µPD16837 is a monolithic quad H bridge driver employing power MOS FETs in the output stage. The MOS FETs in the output stage lower the saturation voltage and power consumption as compared with conventional drivers using bipolar
transistors. In addition, a low-voltage malfunction prevention circuit is also provided that prevents the IC from malfunctioning when the supply voltage drops. A 30-pin plastic shrink SOP package is adopted to help create compact and slim application sets. In the output stage H bridge circuits, two low-ON resistance H bridge circuits for driving actuators, and another two channels for driving sled motors and loading motors are provided, making the product ideal for applications in CD-ROM and DVD.
FEATURES
Four H bridge circuits employing power MOS FETs High-speed PWM drive: Operating frequency: 120 kHz MAX. Low-voltage malfunction prevention circuit: Operating voltage: 2.5 V (TYP.) 30-pin shrink SOP (300 mil)
