SLVSHE3 June 2024 DRV2911-Q1
PRODUCTION DATA
The RESETZ pin manages the state of the DRV2911-Q1. When the RESETZ pin is low, the device goes to a low-power sleep mode. In sleep mode, the output stage, charge pump, and AVDD are disabled. The tSLEEP time must elapse after a falling edge on the RESETZ pin before the device goes to sleep mode. The device comes out of sleep mode automatically if the RESETZ pin is pulled high. The tWAKE time must elapse before the device is ready for input.
In sleep mode and when VPVDD < VUVLO, all MOSFETs are disabled.
During power up and power down of the device through the RESETZ pin, the FAULTZ pin is held low as the internal regulators are enabled or disabled. After the regulators are enabled or disabled, the FAULTZ pin is automatically released. The duration that the FAULTZ pin is low does not exceed the tSLEEP or tWAKE time.
