BQ25606: Status Pin when The battery is lacking.

Kami Huang60

Part Number: BQ25606

Dear Sir/Ms.

My customer tested the BQ25606 to remove the battery. Want to know to grab some data.
1. When the battery is not inserted, should the STAT pin be HIGH or 1HZ Blink?
2. What are the conditions of 1HZ Blink ?? (such as OVP / OTP, etc ...)

Best Regards,

Kami,

1. Please refer to FAQ on http://www.ti.com/lit/an/slva924/slva924.pdf Designing A Standalone Single Cell 3-A Charger with the bq25606. Please visit https://e2e.ti.com/support/power-management/f/196/t/890626 for BQ25606: Schematic Review and PCB Layout Design Tips.

2. STAT pin blinks when Charge suspend (input overvoltage, TS fault, timer fault or system overvoltage).

Thanks,

Ning.
