Other Parts Discussed in Thread: LM3410
Hi team,
My customer use LM3410XQMF/NOPB in their project.
But in the test, they met two issues:
1. When Vin=5V, FB Pin is 0.6V and not 0.19V with a backup battery (3.9V charge) connected. The current limit of 50mA was not reached for an unknown reason.
2. When Vin=5V, disconnect the backup battery. The LM3410 consumes approximately 1A of high current and is overheating.
The result we expect is a stable charge current of 50 mA when a backup battery is connected at Vin=5V. When the backup battery is disconnected, the device is automatically protected from high current.
Could you please help give some comments or suggestions on these questions ?
Thank you in advance!
Regards,
Ivy
