Part Number: BQ24620 Hi
I have a query need your help.
According to the datasheet, the BQ24620 can exit the timing fault when the VFB voltage is lower than the threshold voltage 0.125V after entering the timing fault.
During the test, we found that when…

The customer set the Icharge, the problem as below:
According to the current formula in the data sheet, the charging current is 800mA and the set voltage is 0.16V. However, the actual test…
Part Number: BQ24620 Hi Team,
Q1: Timer failure
The document describes that if the battery is not fully charged for 5 hours, it will enter the timer fault state. If CE is enabled or the value is less than the threshold, the timer fault state can be exited…
Part Number: BQ24620 Hello Ti experts,
I am using the BQ24620 with AC-DC adapter 19V and 24V.
I wonder why VBAT voltage is different depending on adapter voltage.
According to Equation 1, I designed the VBAT = 16.8V (R2 = 1M, R1 = 120k)
It can be…

I have a question about BQ24620. Our customer wants to use the Li-Ion battery instead of the LiFePO4 battery with the BQ24620 under the conditions in the example below…
Part Number: BQ24620 hi
we do a new design of Bat charge of LiFe Po4 using the BQ24620 part.
we are usin:
R1: 5.49K, R2: 39k, (14.6VBAT) R7: 261k, R8: 10k (0.6Amp)
VIN: 14.8V
VBAT: 14.6V
when we connect the Bat, begin charging with constant current with…
Part Number: BQ24620 If a thermistor is not connected to the circuit shown on the page 23 of the BQ24620 data sheet or to the BQ24620EVM board, would charging still work or would it be disabled?
Thanks,
