MOS INTEGRATED CIRCUIT
µPD16857
MONOLITHIC 6 channel H-BRIDGE DRIVER
DESCRIPTION
µPD16857 is monolithic 6 channel H-bridge driver employing power MOS FETs in the output stages. 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
three channels for driving sled motors and tilt control, and another channel for driving loading motor are provided,
making the product ideal for applications in DVD-ROM/DVD-RAM.
FEATURES
• Six H-bridge outputs employing power MOS FETs.
• High speed PWM drive corresponding: Operating input frequency 120 kHz (MAX.)
• Low voltage malfunction prevention circuit: Operating control block voltage under 2.5 V (TYP.)
• Loading into 38-pin shrink SOP (300 mil).
