BQ25892: Boost mode shuts off when discharge current is more than 100mAmps

Part Number: BQ25892
Other Parts Discussed in Thread: TEST

Using BQ25892 standalone IC.  1s configuration is implemented. Boosting from 3.6V to 5V.

While using OTG mode the discharging current does not exceed 100mAmps. Any current more than 100mAmps OTG mode shuts off. 

I have disabled watchdog timer, CHG_config=0,. Nothing else is touched.


  • Hi,

    What are your test conditions such as VBUS (voltage at VBUS pin), IVBUS (actual OTG load), VBAT (voltage at BAT pin), IBAT, VSYS, ISYS? Could you please provide all register values of the charger when OTG load current is below 100mA and above 100mA respectively?
