The PD168117 is a 7-channel H-bridge driver with a micro step function supporting pulse input that consists of a CMOS control circuit 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. Moreover, at the PD168117, micro step control of 128 divisions can perform stepping motor drive by the pulse input, and motor can be driven by low noise and low vibration. The package is a 56-pin WQFN that helps reduce the mounting area and height. The PD168117 can be used to drive two stepping motors, or two DC motors and one coil.
