LV8773 Datasheet (Sanyo Semicon Device) - PWM Constant-Current Control Stepping Motor Driver

LV8773, PWM Constant-Current Control Stepping Motor Driver

of operation (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 standby mode.
