Hi,
I have a BQ25628EVM connected to single cell Li-Ion batterypack. A µC activates OTG (REG0x18_Charger_Control_2 EN_OTG = 1) at start and resets WD (REG0x16_Charger_Control_0 WD_RST = 1) periodically. 47R loads are at SYS and VPB (PMID). All other is default.
When I connect board to USB or 5V power supply, VSYS mostly breaks down. About 5 ms after VIN rises VSYS breaks down for about 10 ms and then came back. So the hole system, powered from VSYS would get a reset. What am I doing wrong? What can I do?
Best regards,
CB
