µPD168102
MONOLITHIC 6-CHANNEL H BRIDGE DRIVER
DESCRIPTION
The µPD168102 is a monolithic 6-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 µPD168102 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 be significantly reduced.
Of the six output channels, four channels are voltage drive type and two channels are current drive type (voltage
drive is also possible). The current drive method of the µPD168102 is the output chopping method, which realizes
lower power consumption drive than the conventional high-power-dissipation linear drive method.
The µPD168102 is housed in a 48-pin WQFN to decrease the mounting area and height. The µPD168102 can
simultaneously drive two stepper motors and two DC motors and is ideal for the motor driver of digital still cameras.
