SLVSAS7D February 2011 – March 2021 DRV8801-Q1
The control input, nSLEEP, is used to minimize power consumption when the DRV8801-Q1 device is not in use. A logic low on the nSLEEP input disables much of the internal circuitry, including the internal voltage rails and charge pump. A logic high on this input pin results in normal operation. When switching from low to high, the user should allow a 1-ms delay before applying PWM signals. This time is needed for the charge pump to stabilize.
