Part Number: BQ24780S Hello E2E Experts,
Good day.
When I start the charge progress, It starts. When I read the value that was measured from the multimeter, it is wrong. For instance, I set the charge current to 3000 mA, I read 2500 mA from the multimeter…
Part Number: BQ24780S Hello experts.
I set Charge Current () to 2816 mA and Charge Voltage () to 16880 mV to start charging.
However, when the battery voltage is 13200 mV, the charging current is about 1600 mA.
Furthermore, as the battery voltage increases…

Hello experts.
We are working on a prototype battery charging circuit using the bq 24780 s.
I was thinking of making a prototype with the same circuit constant as the evaluation board (bq 24780 S EVM), but I was reviewing the circuit…
Part Number: BQ24780S Hi team,
Datasheet states "If the ACFET/RBFET have been turned on for 20 ms, and the voltage across gate and source is still less than 5.7 V , ACFET and RBFET are turned off.", but meanwhile, minimum gate drive voltage on ACFET…
Part Number: BQ24780S Hi Team,
My customer found a issue that they cannot enter hybrid boost mode when battery fully charged. Please see the log as attachment.
I checked that system already meet all required condition of hybrid boost mode as below:

Hi
I have a query need your help.
If I disable ACFET and RBFET, first connect the battery then connect the adapter, the BATDRV is high, current will inrush to battery. Does it normal?
Attached the schematic for your reference.
