BQ24171: Battery Absent

Part Number: BQ24171

Hi All,

We are using BQ24171 in one of our design.

We have following observations when Battery is absent.

1. At power on, 0.8V is observed at "Charge current sense resistor" (Battery side)

2. After sometime, 12.6V is observed at "Charge current sense resistor" (Battery side). Voltage is dropping to 9V at each 500us period.

Query :

1. What is the expected output at Charge current sense resistor when Battery is absent?

Regards,

Pankaj
