BQ24650: Precharge to fast charge transition

Part Number: BQ24650

Hello team,

My customer want to change the threshold for transition of precharge to fast charge.

R1 and R2 is set to 10k and 106.8k, respectively. With this setting, they want to start fast charging with output voltage=5V.

Can we propose an external circuit for this requirement? With current setting without external circuit or something, fast charging will be started from output voltage=18V.

Best regards,

Shotaro
