Hi,
I have to program and test our PCB with bq2710. My software programs it with a battery profile data, which seems to be done all right as our application software can display different charge levels of the battery on the screen. But my test of bq27510 fails intermittently. My method of testing bq27510 is as follows:
1. First we apply 4.5V to BAT, or pin 4.
2. Confirm that BAT_LOW/, or pin 12, is not active, or high.
3. Then we apply 2.4V to BAT.
4. Wait for 3sec.
5. Then we check BAT_LOW/ if it is active, or low. ----> THIS CHECK FAILS; bq27510 does not activate BAT_LOW/.
I am wondering if this test is valid for bq27510. Any inputs will be appreciated.
