Other Parts Discussed in Thread: BQ24133
Hello,
Can you please advise if the below behavior is normal? Do we expect the output voltage to collapse with no cell connected? The status LED is telling me there is an issue:
- The customer has a bq24130 EVM with no rework done.
- The input voltage is 12V
- The output is set to Single Cell (4.2V)
- There is charged cell connected to the output
- Multimeters are connected to the input at J1 and the output at J2
- The output voltage is equal to the cell voltage, between 3-4V in this case.
- The status LED is on
- If the cell is removed the charge voltage falls to 0.8V
- The status LED starts blinking
Any tests the engineer can try on their bench to identify the issue are appreciated! Thank you,
Regards,
Ryan B.
