7-CHANNEL H-BRIDGE DRIVER
WITH A MICRO STEP FUNCTION SUPPORTING PULSE INPUT
DESCRIPTION
The µ 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 µ 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 µ PD168117 can be used to drive two stepping motors, or two DC motors and one coil.
