Part Number: BQ24158 Hi,
We are using the battery charger BQ24158FFT in our design. Our targetted charge current is 100mA and we are using the Rsns as 820mE. But it is only taking 30 mA as charging current.
Below is the register configuration maintain…
Part Number: BQ24158 Hi,
We are using the battery charger BQ24158FFT in our design. We are planning to use it in OTG mode also. But, when it switches to OTG mode - it is draining around 800 to 900mA from battery even in no load condition. Hope you can…
Part Number: BQ24158 Hi,
We are planning to use BQ24158YFFR in our design as the Battery charger. As per my understanding from the docs, we can either operate the Battery charger in 15mins mode or 32 secs mode. But in both modes, the system MCU has to take…
Hi Sai,
I don't understand the issue. The only register that locks is SLR after the first write to any register. The charger's 7-bit I2C address is 6A not 6B like some other members of this charger family. The host should be able to write to the…
Part Number: BQ24158BQ24158 (register05 bit5 reset to 1) Special Charger register in charging IC will be reset to 1 (low charge current) when device entry standby mode and wait over 5 sec then wakeup.
Does TI know what condition will cause the register05…

Part Number: BQ24158BQ24158YFFT I2C register write and read issue.
We found the write data and read data are not the same and below is my write/read process, register and data.
1. Write BQ24158 register 0x02, data 0xb6,
2. Read Bq24158 register 0x02…
Part Number: BQ24158 Hi,
My customer is wondering if the I2C interface can also used 3.3V pull up?
Will there be any risk using 3.3V pull up?
Since 1.8V is mentioned in our datasheet but customer is having 3.3V at their host side.
Great thanks for your…
Part Number: BQ24157 Other Parts Discussed in Thread: BQ24158 , Hi Team,
My customer using both ICs and according to the datasheets, both have the same slave address (7 bit):
0b110101 1
But, both only respond to 0b110101 0 can you please clarify this?
Everything…
Part Number: BQ24158 Other Parts Discussed in Thread: BQ24153A , I attempt to use bq24158 to charge Li-lon battery, Vfloat = 4.4V. When I try to modify the register data via the GUI tool BQ24153A_9 EVM, I setup Battery Regulation Voltage = 4.4V, Maximum Battery…
