BQ27531-G1: About register Chrgr_TermTimer_Reg5()

Part Number: BQ27531-G1
Other Parts Discussed in Thread: BQ24193, BQSTUDIO

Hi everyone,

We are developing a charger using bq27531-G1 and bq24193.
Please tell me about the timeout setting of bq27531-G1.
We set Chrgr_TermTimer_Reg5() to 0x18. Timeout is 5 hours.
Chrgr_Fault_Reg9() became 0x30 in 2 hours and 14 minutes from the start of charging.
The SOC value when the timeout occurred was 0x27 (39%).
what is the reason?

Thank you in advance.
Best regards,

k.saito
