I am developing a board with bq25616 .
The idea is that a AC/DC converter powers the board through the bq25616 and also charges a battery. So when power runs out the boost is suposed to kick in so that the 5v bus in the board stays up and keep a uC from reseting. The thing is, the charger is not working properly, i soldered 2 boards and in one the follow happen:
- one of them works properly but when the battery isn't connected the STAT pin blinks in a weird pattern thaat is higher than 1hz. Also, after reseting the power input the charger only resets after the OTG has a little 0v input for couple seconds, is this intentional ?
- The other board is mounted using the same components but for some reason it doesn't charge ou enter boos mode, the Stat pin keeps blinking evenn if the TS pin is ok and there are no Overvoltage faults.
What am i missing here?
Here is the part of the circuit with bq25616
