PRODUCTION DATA.
| Use the following sequence to power down the device and its supplies: | ||||
| 1. | If time permits, enter shutdown (sequence defined in Shutdown Sequence); else, in case of sudden power loss, assert PDN = 0 and wait at least 2 ms. | |||
| 2. | Assert RESET = 0. | |||
| 3. | Drive digital inputs low and ramp down PVDD supply as follows: | |||
| • | Drive all digital inputs low after RESET has been low for at least 2 µs. | |||
| • | Ramp down PVDD while ensuring that it remains above 8 V until RESET has been low for at least 2 µs. | |||
| 4. | Ramp down AVDD/DVDD while ensuring that it remains above 3 V until PVDD is below 6 V and that it is never more than 2.5 V below the digital inputs. | |||
