DESCRIPTION
The µ 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 µ 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 µ PD168113 can be used to drive two stepping motors, or two DC motors and one coil.
