I have a problem using the BQ25619e. i have set REG07 to 0x00, so BATFET should be enabled and the BQ should not enter in shipping mode. But sometimes (at random time) the BQ25…
Part Number: BQ25619E Hi Team,
My customer is looking for the following answer:
Can the BQ25619E start up in default HW mode when QON_not is not driven.
Reason for this is cost and space and not make HW circuit to generate pulses. The critical…

I am using BQ25619E IC on board with following schematic.
I have not programmed the IC and have connected a 2.6V battery. I connected both CE and PSEL pin to ground (GND).
Now, I am connecting USB Board with…
Part Number: BQ25619E Hi there,
I understand during battery charging, battery temperature would be monitored through TS pin, and charge current could be derated based on the JEITA profile. However, my questions are:
1) When the battery is not charging…

Part Number: BQ25619E Hi, I am working on a project that will use BQ25619E as the charging IC and use it to charge a LiPo battery using a USB power adapter(5V). So when there is a USB supply then we like to use the entire power from the USB VBUS and don…
Part Number: BQ25619E Reading BQ25619E datsheet I didn't understand which is the behaviour of system voltage when nop ower is present on Vbus pin but there is a battery charged connected at VBAT pin. In this situation the Power Path Management connects…
Part Number: BQ25619 Hi Team,
My customer have a voltage accuracy question for BQ25619 and BQ25619E.
When the register 0x04[7:3] is set to "00110" (4.1V), we measure differential Vreg on same FW, HW and temp.
The battery charge to 4.086V on BQ25619E…
