Part Number: BQ24001 Other Parts Discussed in Thread: BQ25170 , BQ24040 After my battery is charged, is there a way to hold the battery at full charge? Do I have to disable and enable the charge pin or can I keep the charger in constant charging so it…
Part Number: BQ24001 Hi,
I found this IC I want to use for charging a Li-Ion in my student project.
I tried to recreate the schematic from the datasheet but I can't find enough information about the APG/THM Pin.
I understand it's either to check supply…
Other Parts Discussed in Thread: BQ24001 Hi-
Is there a limit to the size of the decoupling capacitor that can be placed in parallel with the battery, i.e. from the BQ24001 output to ground? The data sheet shows 1.0uF while the manual for one eval board…
Other Parts Discussed in Thread: BQ24001 Hi-
What voltage should I expect to see at the output terminals pins 18, 19 (TSSOP20 package) of a BQ24001 charger IC when Vin pins 2, 3 is powered (approx 5V) but no battery is connected?
Thanks,
Randy
Hello Shinichi
The BQ2057C is a very old device released about 2001. We have a number of other devices that charge single cell Li-Ion from a 5V supply with higher efficiency and very few external parts. See BQ24040, BQ24090 small high efficiency solutions…
Hello
A couple of other device to look at, if the input voltage is 10V or less take a look at BQ24001, 02 or 04. If the input voltage is 5V take a look at the BQ2404X family of devices.
For higher input voltages an output current we have switching converters…
