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: 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 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…
Part Number: BQ25619 I used the BQ25619 and set the following:
Charge Current: 900mA Termination Current: 160mA JEITA Cool I-SET: 20% ICHG
In the Cool range, the charge current is confirmed to be 180mA, as set. However, the time it takes to fully…
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,
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…
Part Number: BQ25619 Hi Sir,
As the title suggests, when I use a 3.7V battery to boost the voltage to 5V for the PMID output, without an external power supply, will there be voltage backflow from the PMID into VBUS? My software settings have Q1 disabled…
Part Number: BQ25619 Other Parts Discussed in Thread: BQ27427 Hello,
We have used BQ25619 in our battery charging. Right now we are not able to charge the battery, I am attaching the schematics below. Can someone please look into it?
Thanks,
Jay…
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,
Jacob
