Team,
My WW AA customer needs some help, could you have a look below. I appreciate an answer by Wednesday March 29th.
We are considering the following power turn on mechanism:
1) 5V supply is externally turned on
2) PMU tp65912/22 starts up, output voltages stay low, I2C becomes active
3) The connected embedded system (host) configures the PMU and then enables the voltages
4) PMU starts voltage ramp up and sequence, as configured for the give requirements
Can you provide an application note on how to setup the PMU for the above behavior?
