BQ51051B: Additional indicator design

David Park

Part Number: BQ51051B

Hello,

Customer would like to add indicator for full charge with green LED.

Red is for charging and green is for full charge.

Do you have any idea for it? or could you recommend proper device?

Thanks.

    The bq51051B does have a /CHG pin that will indicate device is charging. But does not have a pin to indicate charge complete. Device will send a charge complete command to TX to stop power transfer but this is embedded in a serial string.
    Is the customer using a specific TI TX?
