Part Number: BQ25628 Hi team,
We have several questions regarding OTG operation of the BQ25628.
IOTG Regulation Status
The datasheet description of the IINDPM_STAT register mentions "IOTG regulation".
Our understanding is that, during OTG…
Part Number: BQ25628 Hi team,
Background: We are using the recommended PMID_GD circuit with a 10-k ohm pull-up resistor connected to REGN. We understand PMID_GD is an open-drain output and that REGN is disabled in Sleep mode.
Questions:
During…
Part Number: BQ25628 Looking to implement use this PMIC on an nRF52/54 based system. Looking for reference driver C code. Would take Linux code if that's all that's available. Thanks!

Hi, I’m designing a battery-powered children’s toy and I’m considering the BQ25628 as the charge controller.
For the most part, the controller behaves as expected, but I’m experiencing short VSYS…
Part Number: BQ25628 TI, Has anyone seen an issue with BQ25628 Battery Charger IC where VSYS droops enough (like a negative going pulse over 10-20msecs) to reset my PMIC and MCU? This happens with EN_OTG enabled then applying 5V USB or Qi_Vout to the…
Part Number: BQ25628 Tool/software: Hi,
I am currently running into an issue in my design where triggering ship-mode does not completely off VSYS. My current setup uses 4.2V linear PSU output as VBAT (no charging). When ship mode is entered via I2C…
Part Number: BQ25628 Tool/software: Hello,
I have a product that uses BQ25628 as a battery charger IC, the device was made while referencing the BQ25628 EVM. Everything works fine but at times, TS_ADC stops responding and only reports the same value…
Part Number: BQ25628 Other Parts Discussed in Thread: BQ25629 , Hi team,
We have two questions regarding BQ25628/BQ25629.
In Section 8.3.10.1.1 (Battery Undervoltage Lockout, BATUVLO), what is the battery leakage current when the device enters…
