Part Number: BQ27427 Other Parts Discussed in Thread: BQ24010 Tool/software: Hello,
I notice that during charging or recharging, the WDRESET pin goes high, leading to an ITPOR and causing me to lose all my configuration.
What conditions, other than…
Part Number: BQ24064 Other Parts Discussed in Thread: BQ24061 , BQ24088 , BQ24085 , BQ24010 , BQ24014 , BQ24012 , BQ25611D Hi, Customer has to insert a diode between the OUT pin and the battery for application reasons. I will attach an image diagram.…
Hello
"Can we provide 12V at the input of bq24210 for charging the Lipo Battery?" -- Bill J - Yes, BUT the unit has input Over Voltage Protection (OVP) at 7V and will turn off output, voltage can increase to 20V without damage.
If you need to operate…
Part Number: BQ21040 Other Parts Discussed in Thread: BQ24010 , HI,
Here are some questions about BQ24010:
1. If want #CHG work well while battery remove and insert, I need to disable TTDM, am I right?
2. How the 237kOhm come from? Is there any…
Hello Narukom S
The BQ24040 would not be a good fit for this application, OVP protection will be a problem. This device will operate from 4.45V to 6.45V. When voltage increases beyond this point device will turn off to prevent damage, OVP.
If you…
Hi Thunder,
In some condition (eg. High temp.),Is it unsafe or not occur damage to battery pack? BQ24092 has internal thermal regulation to prevent damage to device, this is much higher than 60C limit of battery pack though.
Is it possible to disable…
Bill,
Thanks for the quick response on this one.
Ill work with the engineer to evaluate if the bq24010 or bq24080 fit better for their requirements.
Best Regards

Hi Kumar,
I understand what happened with the bq24010, the input voltage is directly proportional to the heat loss on the linear regulator.
As for the bq24100, yes, it looks like a switch on the TTC is necessary to reduce current consumption when…
Eli,
TI has an older chargers, BQ24203 and BQ24010, with battery charge voltage at 4.1V but dropout could be as high as 500mV/500mA*200mA = 200mV. Other, newer linear chargers with lower Rdson, have fixed VBATREG=4.2V. However, any of the chargers…
