DRV8848
SLLSEL7 â OCTOBER 2014
8.4 Device Functional Modes
The DRV8848 is active unless the nSLEEP pin is brought logic low. In sleep mode, the VINT regulator is
disabled and the H-bridge FETs are disabled Hi-Z. Note that tSLEEP must elapse after a falling edge on the
nSLEEP pin before the device is in sleep mode. The DRV8848 is brought out of sleep mode automatically if
nSLEEP is brought logic high. Note that tWAKE must elapse before the output change state after wake-up.
When VVM falls below the VM UVLO threshold (VUVLO), the output driver, internal logic, and VINT regulator are
reset.
