Part Number: BQ25619E Tool/software: Hi Team, We are using the BQ25619ERTWR battery charger IC in our design. This BQ25619E interfaced with MCU the pullup logic supply voltage 3.1V for I2C communication interface signals (SCL, SDA) and the other control…
Part Number: BQ25619E Tool/software:
I have a new design with a BQ25619E charging a single LiOn cell at 4.2V
Register 0 value is 0x0A
Register 2 value is 0xBF
Register 4 value is 0x42
When it comes near the end of charge , the charge current decrease…
Hi Jonny,
It was the Voltage booster which was draining the more power than the charger power. So, when I turned off the voltage booster. The charger is now charging the battery from its cut-off as well as when in normal state. I am also shutting off…
Part Number: BQ25619E Greetings,
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 USB Protection…
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 Other Parts Discussed in Thread: BQ24298 , BQ24195
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 enters…
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 situation…
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…
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…
