BQ27542-G1: Max of FCC?

Jamie Tseng

Part Number: BQ27542-G1

Hi Team,

May I know the max FCC (mAh) limit of BQ27542-G1?

If the design capacity is greater than 14500mAh, can it be adjusted proportionally (eg * 10 or / 10), so that the battery capacity greater than 14500mAh can be applied?

Thanks and best regards,

Jamie

    You could divide all capacities by 10 and configure the current measurement (combination of sense resistor and/or calibration CC Gain) to measure 1mA for a true 10mA current.

    Make sure you run a learning cycle with these settings so that the gauge learns QMax and impedance accordingly.
