update:

Charg current = 1A

Hi Tsai,

Can I understand that the max output current will be 1A? then the input current will be below 2A.

Whether load disconnect is needed?

If the answer is yes, TPS61378 and TPS61376 are recommended.

TPS61376 uses input average current limit.

If the answer is no, TLV61048 is recommended.

Best Regards

Any suggesttion?

Hi Tsai,

Could you please describe the of function of LED status?

Also, I'm not so clear about the NTC input.
