Description The pd168116a 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. The pd168116a can drive a stepping motor by inputting pulses, so that the number of signal lines necessary for controlling the motor can be decreased.
The package of pd168116a is a 56-pin WQFN that helps reduce the mounting area and height.
The pd168116a can be used to drive two stepping motors, or two DC motors and one coil.
