µPD168102
Stepping Motor Driver
Monolithic 6-Channel H Bridge Driver Circuit
Overview
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.
