7-CHANNEL H-BRIDGE DRIVER

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 compared 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 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
PD168116A can be used to drive two stepping motors, or two DC motors and one coil.
