AM2632: Power limited Recovery Issue

Lawrence Wang

Part Number: AM2632

Tool/software:

Hi experts,

Our customer reported the following issue:
After the AM2632 operates normally, when the 3.3V supply drops to around 2.96V, the device stops working. Even after the 3.3V supply recovers, the device does not resume operation. Is this caused by exceeding the voltage threshold? What could be the reason for this behavior?

    Apologies for the delay,

    The device dropping below the voltage threshold is stopping operation. The device will need to be reset to resume operation. The PMU on the device contains a safety system with voltage monitors that should automatically reset the device if the voltage drops below the threshold. 

    Are the voltage monitors enabled?

    Regards,

    Susan
