PWM type single channel H-Bridge DC brushed motor driver for automotive use
1. Outline
This product is a motor driver IC which incorporates the output driver
for the direct drive of a DC brushed motor intended for the automotive
use.
The motor drive output can be highly efficient operation by the PWM
control which realizes low-on resistance.
Forward / Reverse / brake mode can be selected according to PWM1 signal and PWM2 signal, and the
motor operation mode and stop mode can be selected by ENABLE pin.
Moreover, the output current capacity is 5A (max), it is suitable for various automotive applications
such as a throttle and valve control, various engine bulbs, storing of door mirrors, and a seat
positioning.
