LV8711T
Overview
The LV8711T is a PWM constant-current control stepper motor driver which is low consumption, low heat
and high efficiency. The device is suited 2-cell battery applications. Its supply voltage range is from 4V to 16V,
and stand-by mode current drain is almost zero. It can contribute to reduce costs and PCB size because of
the built-in circuit to control current. It also can contribute to safe design of applications by several built-in
protection functions.
