LV8711T中文资料Stepper Motor Driver, PWM, Constant Current Control数据手册ONSEMI规格书

描述 Description

The LV8711T is a PWM constant-current control stepper motor driver which is low consumption, low heat and high efficiency. The device is suited to 2-cell battery applications. Its supply voltage range is from 4 V to 16 V, 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.
