Description The μPD168116A is a 7-channel H-bridge with a tiny step function supporting a pulse input considered a CMOS control circuit by a driver and a MOS output stage. It can reduce current consumption and use bipolar transistors for conventional drivers at the voltage depleted output stage, thanks to a MOS process employment. The μPD168116A can drive the motor step by step by inputting pulses, so that the number of signal lines necessary to control the motor can be dropped. The package is a 56-pin WQFN that helps reduce mounting area and height. The μPD168116A can be used to drive two stepper motors or two DC motors and one coil.
