UPD16833A

•Four H bridge circuits employing power MOS FETs
•Low current consumption by eliminating charge pump VM pin current when power-OFF: 10 A MAX. VDD pin current: 10 A MAX.
•Input logic frequency: 100 kHz
•3-V power supply Minimum operating supply voltage: 2.5 V
•Low-voltage malfunctioning prevention circuit
•30-pin plastic shrink SOP (300 mil) (mPD16833AG3)

The mPD16833A is a monolithic quad H bridge driver IC which uses power MOS FETs in its driver stage. By using the MOS FETs in the output stage, this driver IC has a substantially improved saturation voltage and power consumption as compared with conventional driver circuits using bipolar transistors.

A low-voltage malfunction prevention function is provided to prevent the IC from malfunctioning when the supply voltage drops. By eliminating the charge pump circuit, the current during power-OFF is drastically decreased.

As the package, a 30-pin plastic shrink SOP is employed to enable the creation of compact, slim application sets

This driver IC can drive two stepping motors at the same time, and is ideal for driving stepping motors in the lens of a video camera.
