MONOLITHIC QUAD H BRIDGE DRIVER CIRCUIT
DESCRIPTION
The µPD16833A 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.
