The PD168113 is a serial control 7-channel H-bridge driver that consists of a CMOS controller and a MOS output stage. It can reduce the current consumption and the voltage loss at the output stage compared with a conventional driver using bipolar transistors, thanks to employment of a MOS process. The PD168113 can drive various motor coils by controlling the serial, so that the number of signal lines necessary for controlling the motor can be decreased. The package is a 56-pin WQFN that helps reduce the mounting area and height. The PD168113 can be used to drive two stepping motors, or two DC motors and one coil.
