PD16837
MONOLITHIC QUAD H BRIDGE DRIVER
DESCRIPTION
The
碌
PD16837 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
鈥?Four H bridge circuits employing power MOS FETs
鈥?High-speed PWM drive: Operating frequency: 120 kHz MAX.
鈥?Low-voltage malfunction prevention circuit: Operating voltage: 2.5 V (TYP.)
鈥?30-pin shrink SOP (300 mil)
