Power Loss Sequence (AD BTL)
Use the following sequence to powerdown an AD BTL device and its supplies in case of sudden power loss
when time does not permit a controlled shutdown:
1. Assert PDN = 0 and wait at least 2ms then assert HIZ = 0 and wait at least 4
s.
2. Assert RESET = 0.
3. Drive digital inputs low and ramp down PVCC/AVCC supply as follows:
Drive all digital inputs low after RESET has been low for at least 2
s.
Ramp down PVCC/AVCC while ensuring that it remains above 10V until RESET has been low
for at least 2
s.
4. Ramp down AVDD/DVDD while ensuring that it remains above 3V until PVCC/AVCC is below 7.5V
and observing absolute maximum ratings for digital inputs.
