Part Number: BQ25708 Hi,
This is a followup to the thread which was started here:
https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1116326/bq25708-regn-drops-out-periodically
In that thread I described an issue…
Part Number: BQ25708 Due to supply chain issues, we are looking to substitute MOSFETs in our shipping product. Testing seems good for a MOSFET with plus or minus 12 volt maximum gate-to-source voltage, but our existing design uses plus or minus 20 volts…
Part Number: BQ25708 Hi,
I got an issue with the REGN pin periodically dropping, with the charger chip also rebooting and losing all the configurations.
The REGN pin is driving nothing except for the VDDA pin and two resistors (100Kohm and 59Kohm) to…
Part Number: BQ25710 Other Parts Discussed in Thread: BQ25708 I have a design that uses BQ25708 for either a 3S or 4S Li-Ion battery. Would BQ25710 work as a drop in replacement? Are there any other models that would also work without board changes (BOM…
Part Number: BQ25708 Other Parts Discussed in Thread: CSD17327Q5A Hi, We have aproject ongoing which uses two BQ25708 IC's.
Both IC's have an identical circuit and both have a very similar layout. However one of the IC's is displaying odd behaviour…
Part Number: BQ25708 Hi everyone,
We try to launch a charge cycle with a BQ25708, as we use I2C interface with the SMBus protocol we write in register 14h (Charge current) and register 12h (Charge option) with LSB first.
We read back register and everything…
Part Number: BQ25708 Other Parts Discussed in Thread: BQ40Z50 1 - I set the MaxVoltage to 14v and the MaxCurrent to 10A. When I let the charger running, it seems that the charger does not stop automatically when it reaches 14v. It is still injecting current…
Part Number: BQ25708 Other Parts Discussed in Thread: CSD17551Q3A , CSD25402Q3A Hi All,
We have used the BQ25708 battery management IC in one of the project. The input to VBUS is from 12V to 24V DC & VSYS is supplied to the entire system including the Host…
Part Number: BQ25708 We have a product in production using BQ25708. We are using a 12 Volt lead-acid battery.
The CELL_BATPRESZ pin is connected to the battery via a resistor-divider such that a 12 volt battery applies about 5 volts to CELL_BATPRESZ.…
Part Number: BQ25708 Hi,
I am writing embedded firmware to control BQ25708. Now I found out that the values I read out of BQ25708 like Ibat (register ADCIBAT, 0x24), Iin (register ADCIINCMPIN, 0x25) are delayed to the physical values by some hundred msec…
