BQ27426: BQ27426 application circuit confirmation
Part Number: BQ27426 Hi there, I have a question about the application circuit of BQ27426. According to the datasheet, the charging current is opposite to the battery discharging current, My question is : When the charging circuit works, does the reverse voltage drop on the 10 mΩ sense resistor(SRN-SRP) affect the chip? Subsequent question is: In the case of charging, can the IC also complete the charging current detection. Datasheet recommended applications are as follows, Thanks for your help.
See my comments below. When the charging circuit works, does the reverse voltage drop on the 10 mΩ sense resistor(SRN-SRP) affect the chip? [Andy] No. The current flows in different directions during charge and discharge. In the case of charging, can the IC also complete the charging current detection? [Andy] What do you mean by "charging current detection". The current is always monitored by the gauge.
