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…
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…
Part Number: BQ24650 I was designing a charge controller for the lead-acid battery using BQ24650. As the ambient (atmospheric) temperature here is around 25 to 30 Deg Celsius we want to use the IC without using the thermistor as mentioned in slva437a.
1…
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…
Mohammed,
In order to use TMP61 you need to bias it with either a voltage divider or a current source as seen below:
In this configuration, you can calculate temperature by referring to the "4th order polynomial TMP vs Vdc" page found in the thermistor…
Hi Saeed,
Could you provide the design requirements or schematic you had with the RTD module.?
RTD is PTC, and thermistor is NTC. Are you referring to thermistor sensing element for the application? Please specify and I need to know the NTC type, accuracy…
