BQ24071: calculate charge current

Jhon Jairo Zambrano

Part Number: BQ24071

Hi Best regards

There is any way to calculate instantaneous charge current according to the Voltage in R_ISET1 or R_DPPM ?

Hi Jhon,

No there is not a way to measure the voltage based on the voltage at R_ISET1 or R_DPPM. The voltage on the ISET1 pin will always be about 2.5 V. The voltage across the R_DPPM resistor will also not translate in any way to charge current.

Best Regards,

Anthony Pham
