BQ25155: control the charging current

Guru 29470 points
Part Number: BQ25155

Hi Team,

My customer wants to control the charging current as follows.
Is it possible for BQ25155 to control?

Ta=0~15℃: 9mA
Ta=15~45℃: 135mA

Best Regards,
Yaita

  • Hi Yaita, 

    Yes, with the BQ25155 the customer could configure, then read the ADC_DATA_TS (0x44) registers to obtain the TS temperature reading, and then take any action on their software to change the fast charge current ICHG_CTRL (0x13) to 8.75mA on 0-15C and to 135mA on 15-45C range. Additionality, they can also configure the ADC comparators to trigger interrupts at the temperature thresholds crossing to notify the MCU to take any required action.
