bq24450 is a linear lead acid charger. For switching mode lead acid charger, you can check bq2031. From a linear charger to a switching charger, there are many differences: such as switching FET, inductor... We cannot just replace an IC to convert a linear…
Other Parts Discussed in Thread: BQ2031 According to the BQ2031 Data sheet removing RT1 and RT2 and replacing them with a 100K resistor should disable the temperature monitoring feature. So I removed R2 and R3 on the DV2031S2 board and replaced them with…
See the application notes under the BQ2031, there are some example schematic there.
A comment for TI's product engineering - The BQ2031 specifications really need to be improved, the documents are not well organized and should include at least one sample…
Hello Ryan,
I have 12V input DC source and need to charge 6Volt battery. We had used UC3909 (out pin) switch mode option(Buck) and drop the voltage as per requirement.
Is that Bq2031 can do this job? Please give me some reference.
If not please…
Hi Shreenidhi,
What are they planning to use for the input of the charger? What charge current are they planning to use?
To start, you can look at the BQ2031, which is charger dedicated for lead-acid charging.
Alternatively, you can look at the…
Other Parts Discussed in Thread: BQ24770 , BQ2031 I like the NVDC architecture of the bq24770. It solves a lot of problems for us. However, we need to charge a SLA battery.
Since the bq24770 is host controlled, is there any reason I cannot charge a…
Other Parts Discussed in Thread: UC2909-EP , BQ24450 , BQ2031 , UC2906 Hello!
I need to charge three 6V in series (18V total) lead-acid cells. So, my question is: Which device do I have tu select to manage these cells properly?
UC2909-EP ?
BQ24450…
Hello Sonoki,
Are you willing to consider a linear charger?
The bq24450 can support trickle in pre-charge, bulk, boost (over), and float.
Otherwise the UC2909-EP is still available but it is an Enhanced Product for wider temperatures and it will…
