Part Number: BQ25890 Tool/software: Dear TI Engineer,
We used BQ25890 on one of our products, but found that the charging current was very small to only 0.475A. The adapter output power can reach to 40W.
The schematic is as below:

I have a BQ25890 that I'm using in a portable application and I'm seeing abnormal current waveforms during charging. The current is pulsing, almost like the charge keeps being turned on and off, I'm also seeing…
Part Number: BQ25890 Hi,
My customer is requesting for a schematic and layout review on their BQ25890 design.
Appreciate if BU can help take alook and provide us the feedback. elias-20230324.PcbDoc elias_schematics_DVT.PDF
Thanks,

Hi, TI team. I have a question about BQ25890 fault register (REG0C).
1. I want to know the temperature definition and temperature range of each item (total 8 items below) in case of NTC Fault Status. I couldn't…

Hello,
We are developing a battery charger, and I would like to know if the BQ25890 is the right choice for our application (apart from that, it is so complex, that we…
Part Number: BQ25890 Hello.
I am using the BQ25890 for the tablet charging management.
I found a issue, when the tablet placed a long and long time, the voltage of the battery would low down and go into the over-discharge protection @2.8V, and then…
Part Number: BQ25890 Tool/software: Can this battery charger IC be used for class II medical devices?
Because the words like medical devices are not described in the applications of the datasheet.
Part Number: BQ25890 Hi team,
Could I set BQ25890 to VBUS power supply only on Vsys? what register should I change?
1.REG03[4]CHG_CONFIG set to 0(charge disable), does this status Battery will supply to VSYS?
2.REG09[5]BATFET_DIS set to 1(Force…
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…
Part Number: BQ25890 Dear Team,
At present, according to the table provided by TI's official website, the RT1/RT2/RTH resistance value should be calculated, combined with the actual output value of VREGN, it is found that the read temperature will…
