Part Number: BQ25890 Hi
The customer design with BQ25890, when inserting an OTG device, there was 2.9A peak current, which will pull the 3.6V battery to 2.6V, causing the system to restart.
Is there any way or register to limit the peak current at this…
Part Number: BQ25890 Hi team,
The VBAT voltage of Datasheet Figure 8-1 is 3.8V but, customer want to know the efficiency at VBAT = 2.8V, 3.3V or so.
Could you provide it or, measure it if the evaluation data is not exist?
Best Regards,

Hi Gary,
Gary Teng said: They can't disable stat pin function by setting bit6 in REG06 or bit4 in REG03.
STAT_DIS bit is bit 6 in REG07. Bit 6 in REG06 or bit 4 in REG03 will not disable STAT pin.
I have confirmed STAT_DIS bit works as expected with…
Dear Garrett:
Do you mean, the IDPM_LIM value would not go back after ICO changes it? Or the ramp-up speed is too fast to response for ICO?
The nominal input is 12V and the DMP threshold is set to 6V. There is a Schottky diode and some MOSFETs for Power…

I’m tapping into the I2C bus between our processor and the BQ25890 to see the messages exchanged and register values.
When the processor writes 0x0C to get the status of the fault register, the…
Part Number: BQ25890 There is a problem in the process of using BQ25890: after we turn off the watchdog function, we must delay the configuration of other registers for about 1S(the time may be shorter) to succeed, if there is no delay or a short delay…
Part Number: BQ25890 Hello,
Does the OTG function of BQ25890 only support the OTG function when it is in High ? Or can it support OTG and USB charging together?
Thank you.
