Part Number: BQ24104 Other Parts Discussed in Thread: BQ24103A , Tool/software: We have several boards that use the BQ24104RHLR to charge a simple 2S1P 18650 pack with integrated 10k NTC thermistor.
When we had the charge current set at 2A, many parts failed…
Part Number: BQ24104 Hi Team,
There is a full charging issue on customer's board. Charge status is charge-in-progress after charging 8.33V to 8.4V. Should TCC capacitor be changed to higher value? Please check it and let me know.

Part Number: BQ24104 Hello,
We are seeing a timer fault issue with our charging circuit. We are noticing that the STAT1 LED is blinking after 4 hours of charging.
Initially we had a 100nF capacitor between TTC and GND . In the BQ24104 Data Sheet, using…
Part Number: BQ24104 Hello,
We were trying to debug the issue with our charging circuit not functioning. Our charging circuit is shown below. We have two boards that have have a non functioning charging. There was no indication of short in the Vcharger…

We are currently planning to design a PCB test fixture for a circuit board that has BQ24104 charging circuit section on it. We would like to come up with…
Part Number: BQ24104 Other Parts Discussed in Thread: BQ25306 , BQ24170 Hello,
We would like to verify if we can test our BQ24104 EVM as well our own Charging Circuit PCB (also using BQ24104 IC) with an electronic load connected to VBAT instead of the…
Part Number: BQ24104 Other Parts Discussed in Thread: BQ24103 , Hello,
Our team is currently debugging our BQ24104 charger IC board. We are comparing our results with the data we got from the BQ24103 EVB. Here are our observations
A. With the 2S4P battery…
Part Number: BQ24104 Hi,
A diode (MMBZ18VALT1) has been added from the revision of Revision G to H in the data sheet.
1. Is there any problem if I don't insert the diode? There is a statement in bq24104 that it is not necessary.
2. ON Semiconductor…
Part Number: BQ24104 Hello all, I intend to use the BQ24104 to charge a lithium ion battery pack- but the battery pack I am sourcing does not have a thermistor output. The internal battery management circuit inside of the pack does have temperature safety…
Part Number: BQ24104
If you have any data on the variation of K(ISET1) and K(ISET2), would you please show it?
Customer would like to know min,max value of K(ISET1) and K(ISET2).Datasheet shows typ value(1000V/A) only.
