µPD16833A
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.
