Part Number: BQ24090 Dears,
If BQ24090 will go under SHORT PROTECTION status, when Vout down to 0.8v? Because i connect BQ24090 to Boost IC start working voltage lower than 0.8v, and find BQ24090 stop working.
And what means of Recovery ≥ V OUT(SC) …

As for CHG pin, according to the specification, CHGpin is high level when it is not charged or fully charged, and low level when it is charged. But in fact, when the above NTC voltage is abnormal, CHG PIN outputs high…
Part Number: BQ24090 It is found that when some products are charged, the charging value of the first 10 seconds is only half of the preset current value, and about 10 seconds later, the charging is normal. An oscilloscope was used to capture the voltage…
Part Number: BQ24090 Hi team,
Issue: using the BQ24090, it was found that some products were charging with only half the pre-set current value of the first 10S charging, and after about 10S charging, it became normal. Grabbed the NTC voltage value with…

Part Number: BQ24090 Dear ones shalom
we are using the device and in few occasions we have high temperature in the BQ24090 during charging
we use ISET with 2KOhm and ISET2 is LOW PRET has 2K Ohm resistor
the over temperature is during charging of empty…
