TPS65910 Power Sequence

Other Parts Discussed in Thread: TPS65910, AM3352

Dear all.

Our customer evaluate the TPS65910 for AM3352.
1) When VCC7 has not reached the voltage which outputs 3.3V of VDD2, is the Power control state-machine waiting for execution of a sequence?

2) When VCC7 is less than the voltage which outputs VDD2, is there any situation where VDD2 is not outputted and reset is not assert?
The VCC7 voltage returns again and VDD2 is output.

Regards,

I am not sure if i understood your questions propely.

1. if the value of VMBHI_MSK bit is 1 in the EEPOM application not then that menas device will wait on an external evnet to boot up after VBAT is applied to device. so then you need to press PWRON buttown to wake up the device.

2.. Vcc7 must be high obove VMBHI level for device to boot up.
