UPD168116A Description
The µ 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 pared with a conventional driver using bipolar transistors, thanks to employment of a MOS process. The µ PD168116A can drive a stepping motor by inputting pulses, so that the...
