PD168117A
7-CHANNEL H-BRIDGE DRIVER
WITH A MICRO STEP FUNCTION SUPPORTING PULSE INPUT
DESCRIPTION
The
µ
PD168117A 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
PD168117A, 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 64-pin FLGA that helps reduce the mounting area and height.
The
µ
PD168117A can be used to drive two stepping motors, or two DC motors and one coil.
