Part Number: BQ76942 Tool/software: Hi, our design uses the BQ76942 to manage a 7S LiFePO battery pack.
The BQ76942 is on the product's PCB, while the battery pack (simply bare cells and a thermistor) can be removed and replaced. It is connected to the…
Part Number: BQ76952 Tool/software: Working with the BQ76952, I know that the TS2 Pin can be used either as a Wakeup pin or as a Thermistor ADC. I want to implement both at the same time to enable the SHUTDOWN mode which can then be waken-up through…
Part Number: BQ25306 Tool/software: Hi,
I am using the BQ25306 IC to charge a 10,000mAh lithium polymer battery, and I need to set it up to charge at 3A. Based on the datasheet,
I understand the charge current ratio KICHGK_{ICHG} K I C H G and the relationship…
Hi Nate,
Nate Martin said: My understanding is this would be an over temperature permanent failure (reset on POR of the cells), and that it should be placed as close to the switching fets as possible. Given this, what considerations should go into choosing…
Part Number: BQ76952
Tool/software:
Please experts in the house help! My design is based on the EVM board and for testing i have the following settings as per
the sample code for STM32. I am a novice, please forgive my desgin quality.

Hello,
I would recommend placing a resistor in series and parallel to modify the threshold of your 10k thermistor going to 4k at 45C such that the TS voltage is below VTS-60°C at that time. This will require some theoretical iteration to meet your desired…
HI Makabongwe,
BQ25792 is not designed to be used without a battery. I recommend switching to BQ25798. The ADC still functions even if the IC is in HiZ mode. If charge is disabled, BAT pin sits around 2.5V until a battery is inserted. Not sure you even…
Hello Mohd, 1. Yes, we can provide those schematic and board design files: BQ25750_Design_Files.zip 2. There are two ways to adjust the constant current value. You can change the ICHG pin resistor or you can change the ICHG register. The IC will pick the…
Part Number: BQ76952 Tool/software: Dear TI support team,
We are using BQ76952 to design a BMS monitoring and control system, which is low-side control by DDSG and DCHG pins through TI MOSFET drive IC UCC27524AD. Everything is fine unless recently we…
Part Number: BQ24650 Hai,
I have designed BQ24650 for my lead acid battery and now its in the testing stage. there are a few problems that i face now.
1) the Mppt voltage remains at 0.4V. But once i removed Q2 its working fine. so now there is no reset…
