Part Number: BQ24103A
I require an IEC compliance certificate for the BQ24103ARHLT battery charger IC. I was unable to find this on the website. Can you please provide a copy or a link to where I can find it. Thanks.
Part Number: BQ24103A Hi team,
The input supply for VCC and IN is 5 V. Charge two lithium batteries (8.4 V) in series, the charge status indicator does not light when the battery is plugged in. If there is no battery, the charging light turns on.
Changing…
Part Number: BQ24103A We have a product using BQ24103A controlled by a now EOL MCU (AVR ATTINY84V)
So we plan to re-spin the board and use our host CPU to control the charging chip instead and drop the AVR MCU. Is the BQ24103A still active and a good choice…
Part Number: BQ24103A Hi team,
Here's an issue may need your help:
Currently charges 2 4.2V 18650 batteries.
Issue: some of the charging is extremely slow, stops after charging, and the battery stays around 1.5 V. Is there anything wrong with the…
Part Number: BQ24103A Other Parts Discussed in Thread: BQ24103 , BQ25302 , BQ25616 Dear support team,
regarding the bq24103(A), I am wondering what happens if the DC power supply (applied to pins IN and VCC) is not able to deliver sufficient current to charge…
Part Number: BQ24103A When the battery is fully charged, is there any residual current? Or is it off?
Also, can you please verify the following:
CELLS_FB=VCC
ISET1=5.23K
ISET2=10K
The sense resistor is 100mOhm
Any input is appreciated!
Thanks,
Jack …
Hi Craig,
Per the datasheet, the TVS diode is required. The BQ2410xA and BQ2412x versions were released with fixes to prevent damage that the TVS diode prevented. Unfortunately, there is not a BQ24104A only a BQ24103A. Can you change to a TVS with capacitance…
Part Number: BQ24103A Other Parts Discussed in Thread: BQ25886 , BQ24133 , BQ25606 , BQ2586 Hi Team,
The input voltage to BQ24103ARHLT is 12V. My battery is a two-cells one. However, when the battery is being charged, the input voltage becomes 8.5V. And…
Part Number: BQ24103A Hi:
When testing BQ24013A to charge double-core lithium batteries, it was found that the OUT voltage was only 8.28v, which could not reach the 8.4v mentioned in the manual. As a result, the batteries could not be filled. Please…
Part Number: BQ24103A How do we calculate the proper inductor value. The datasheet uses 30% inductor ripple current for the calculation. Does the ripple current have a range or does it have to be 30%
