Part Number:BQ2057C
Hai,
I am using BQ2057CSN Li-Ion charger IC to charge 3.7V Battery ,
Attached is my circuit FYR
To disable TEMP SNS pin I am applying VCC/2 Voltage and battery is getting charged
But when ever there is no main power and only battery is present in my device there is reverse voltage appearing at R4 Resistor,
Please check and update if there is any change that requires in circuit or because of mosfet switching behaviour that is happening,
Regards
Jyothi
