Hi,
This is related to my previous question regarding BQ24618 as I have been looking into the design again.
The BQ24618 circuit is part of a larger charger design which has had two versions. The circuit I shared previously is almost identical between the two versions, the major change being the input to the circuit: Version 1 had no reliability issues and used a conventional DC adapter, whereas version 2 uses USB PD. Both provide 20V, however the USB-C has a slower rise time (~150us vs ~25ms).
Does BQ24618 have any requirements regarding input voltage ramp up time? Could the slower rise in the second version cause these random failures and is it worthwhile to implement a separate enable circuit?
Thank you for your help!
