Hi Myrto,
It is good that there is minimal voltage difference between battery and BQ25628 BAT pin with no current flowing, but that does not mean there is no voltage drop with current applied.
As stated in my previous response with the device in charge…
Part Number: BQ25628 Tool/software: Hello,
I have designed a battery charger using BQ25628 and I designed RT1 & RT2 resistors for an 103AT NTC thermistor.
Basically, I followed suggestions in the datasheet for this design.
I tried to get all the…
Part Number: BQ25628 Tool/software: Hello,
I am using the BQ25628 charger IC in our circuit, and on a few of our boards, we're encountering an issue where the VSYS supply voltage drops randomly. This causes our system to restart repeatedly
The issue…
Part Number: BQ25628E Other Parts Discussed in Thread: BQ27Z746 Tool/software: Hi Team,
We are currently using the charger IC BQ25628ERYKR in conjunction with the fuel gauge BQ27Z746YAHR for charging and monitoring a 3.7V, 1500mAh LiPo battery in our…
Part Number: BQ25628 Tool/software: Looking to implement use this PMIC on an STM32 based system. Looking for reference driver C code. Would take Linux code if that's all that's available, but C i2c driver is preferred. Thanks!

Hi,
The battery discharge current is dependent on the SYS load. The charger does not limit discharge current unless it triggers battery overcurrent protection which is independent of thermistor temperature. Please refer to 8.3.10.1.2 Battery Overcurrent…

Part Number: BQ25628 Can Vsys set to 4.15V?
The application diagram shows it can as shown (attached) on the 1st page of the datasheet.
But Vsysmin in the table shows Range: 2560mV-3840mV (20h-30h).
Is there a range for Vsysmax?
We want to set Vsys = 4…
