μ PD168105
MONOLITHIC 5-CHANNEL H BRIDGE DRIVER
DESCRIPTION
The μ PD168105 is a monolithic 5-channel H bridge driver IC consisting of a CMOS controller and a MOS output
stage. Because it uses a MOS process, this driver IC consumes less current and loses less voltage at the output
stage than conventional driver ICs that use bipolar transistors. In addition, the μ PD168105 employs P-channel
MOSFETs in its output stage, eliminating the need for an on-chip the charge pump circuit. Therefore, the current
consumption during circuit operation can significantly be reduced.
Of the five output channels, four channels are voltage drive type and the rest one is current drive type (linear drive).
The μ PD168105 is housed in a 36-pin FLGA to decrease the mounting area and height. The μ PD168105 allows
combination of two stepper motors, one DC motor and one coil to work. Therefore, it is ideal for the motor driver of
digital still cameras.
