Part Number: BQ24157 Tool/software: VBUS on BQ24157 remains at 4.2V even after removing 5V USB AC adapter. 4.2V remains stable for a period of time that varies depending on PCB assembly, from 10ms to over 6 hours. When USB connector is removed 4.2V is…
Part Number: BQ24157 Hi,
We have one product that uses the TI charging IC – BQ2415YYFFR and having issues with passing the EMI (RE) certification test.
We tested different configurations and found that moving the RC filter (C5 and R5) before the inductor…

Dear Sirs and Madams,
We are using BQ24157 in the following general configuration.
When the BQ24157 is charging the battery, and the AC adapter is unplugged, it appears…
Part Number: BQ24157 Hello, technical staff of TI
I have using BQ24157, b ut I found that when the battery voltage is below 3V, the BQ24157 does not work properly.
I read the specification that when the battery voltage is lower than Vshort, there…
Part Number: BQ24157 Hi,
We are using the BQ24157SOC in our charger product. I see some unseal behavior like once battery is full and if I re-insert the battery then I intermediately get the fault code #4. It seems fault code 4 means OUTPUTOVP, is that…
Part Number: BQ24157 Other Parts Discussed in Thread: BQ25619 , BQ25618 , BQ25611D Dear TI engineers,
Does TI has IC similar to BQ24157 but with powerpath function?
CC 100mA
System supply current 2-3A
(Battery: 180mAH on TWS wireless Bluetooth…
Part Number: BQ24157 Hi.
We are performing some tests on the BQ24157, and observed that, contrary to the datasheet, it does not automatically enter into high impedance mode upon VBUS<VUVLO, rather continuously reports a fault for the same (011-Bad…
Part Number: BQ24157 Other Parts Discussed in Thread: BQ25100 Hi Team,
Can i know how to use low charge mode of BQ24157? What scenario we will use low charge mode in?
What's the recommended setup to limit the max charge current to be 160mA? Thanks…
Part Number: BQ24157 Hi TI Team,
Our customer using BQ24157 on their new project and encountered a problem that register 0x06 cannot be written. From the datasheet we learned that the 0x06 register can be written only after reset, and it was locked…
