UPD168002 - Integral 6-Channel H-Bridge Driver...
Described by the μPD168002 is a monolithic 6-channel H-bridge driven CMOS control circuit and a MOS output by stage. It can reduce current consumption and voltage loss at the output stage with conventional drivers using bipolar transistors, thanks to a MOS process that works. In μPD168002, P-channel MOS transistor field effect transistor output stage is used, and the charge pump circuit is eliminated. Therefore, the current consumption operation in the circuit can be greatly reduced. The package is a 48-pin TQFP, which helps reduce mounting area and height. The μPD168002 can be used to drive one stepper motor and four DC motors and is a motor driver suitable for CD-ROM/CD audio.
