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. | |
