Part Number: BQ25619 Tool/software: Hello Vi have several prototypes where the BQ25619 charger is used to charge a LI-ION battery (Tandiran 1550A). The battery charging current is set to 100mA and termination current is set to 20mA. Vi are experiencing…
Part Number: BQ25619 Tool/software: Hi expert,
Something wrong with the bq25619.
The MCU writes a charge current of 1 . 18A through I2C , and the battery will be discharged to 3V .
P roblem 1 : S hutdown the device, t he c harging c urrent will be 6 00mA. A nd turn…
Part Number: BQ25619 Tool/software: Hello all.
I am designing a circuit using the TI BQ25619 chip.
However, the recommended power inductor size from TI is too large, and I would like to change it.
I am planning to use a charging current of 500mA, and…
Part Number: BQ25619 Tool/software: Dear expert:
When VSYS-min is 3.7V and Voltage of The case is 3.5V , Current of case has 20mA , Now we adjust the VSYS-min is 3.2V, Current of case has 0mA, The issue is solved ,but we have doubt , VSYS-min have changed…
Part Number: BQ25619 Other Parts Discussed in Thread: BQ24640 Tool/software: Dear TI Support Team,
I have a couple of questions regarding the BQ25619 charger IC and its compatibility with super capacitor charging, as well as recommendations for an appropriate…
Part Number: BQ25619 Tool/software: Hi Expert,
During the test, I have found that the BQ25169 charges the case under a weak power source.
Assuming that the USB only supplies 200mA, and the headset requires 300mA, will the chip also charge the case,…
Part Number: BQ25619 Tool/software: Hi team - I see the compliance certificate in the related E2E question. Do we have the full compliance report available to share to customers for their certification efforts?
Thanks,

Part Number: BQ25619 Tool/software: I am working on a design that uses a BQ25619 charger chip.
Unfortunately my hardware designer made an error and pulled PSEL high so the chip things it is connected to a USB socket when it is actually connected to a…
Hello Michael, I have another question on my mind. please see the below image in which I have connected TS from the charger BQ25619 to the gauge BQ27427's BIN pin, if TS is biased with 53% then the voltage is 2.5V, and BIN pin's absolute maximum rating…
