Hello everyone,

the IC labeled “D4W28” gets hot after a few seconds and the iCharger stays off. I have measured the components around the ICs “AL114” and “D4W28” and they are all OK.
However, I have the problem that I can't find the ICs and therefore have no datasheet. Do any of you have the datasheet to hand? Also, do you know where I can buy these ICs?


Thank you in advance,

Phil​
