LV8772 Datasheet (ON Semiconductor) - PWM Constant-Current Control Stepping Motor Driver

LV8772, PWM Constant-Current Control Stepping Motor Driver

of operation Input Pin Function (1) Chip enable function This IC is switched between standby and operating mode by setting the ST pin.

In standby mode, the IC is set to power-save mode and all logic is reset.

In addition, the internal regulator circuit and charge pump circuit do not operate in
