Hi Parth,
The current at SYS output is dictated by the load connected not the charger IC. BQ25890H can support a system load up to the 5A rating of the device.
The expected timing for SYS to reach set voltage after VBUS is attached will vary depending…
Part Number: BQ25890H
There's a question about the voltage at the SYS pins when operating from battery only.
Please clarify what happens to the voltage at the SYS pins, relative to the voltage of the battery at the BAT pins, when the OTG pin pulled…
Part Number: BQ25890H Hi
The customer design with BQ25890H, The REGN pin is connect to the CBL_PWR_N of SG865W. It is expected that the device can start automatically wake and start to charging after inserting the USB.
But the problem is when no USB is inserted…
Hi James,
James Steenbock said: 1. Can you provide a schematic of the charger portion of your system? It would help to check any potential hardware issues.
This issue is 5% of probability. I haven‘t caught any usefull waveform yet. I will catch it continuely…
Part Number: BQ25890H Hello TI Team,
can you please contact me via E-Mail (this account email address) for the design review, because our project is confidential and I can not publicly post the design files?
Thank you in advance!

Part Number: BQ25890H Hi team：
I have a question about BQ25890H to consult:
Does BQ25890H have a function similar to "anti-shack"?
For example, VBUS transient voltage below VBUS threshold, and device wouldn't trigger undervoltage protection…
Part Number: BQ25890H Hi team,
The 4.7uF capacitance on the REGN pin, can we replace it with 2 x 2.2uF capacitance?
My customer wants to reduce noise when calls through 2 x 2.2uF capacitance.
Thanks
Best regards
Lillian
