µPD168112
Stepping Motor Driver
Monolithic 6-Channel H Bridge Driver for DSC
Overview
The µPD168112 is monolithic 6-ch H-bridge driver LSI which uses power MOSFETs in the output stages. By using the MOS process, this driver LSI has substantially improved the voltage loss of the output stage and power consumption as compared with conventional driver circuits using bipolar transistors.
By eliminating the charge pump circuit, the current during power-OFF is drastically decreased.
In addition, a low-voltage malfunction prevention circuit is also provided that prevents this LSI from malfunctioning when the supply voltage drops.
This LSI can drive stepping motor, DC motor or coil by serial controlling, and this driver is suitable for driving DSC motor.
Features
- Six H bridge circuits employing power MOSFETs
