UPD16857 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 pared 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.
UPD16857 Key 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)
