Part Number: BQ24780S Dear TI Engineer,
We encountered the following issues when using BQ24780S on the Notebook: The notebook is not connected to the battery, theoretically QB4/QB5 does not work, but we measured a leakage voltage of about 0.8V at…
Part Number: BQ24780S In current design,IADP and IDCHG pins have a 100pf decoupling capacitor separately.
For system design, we do not use IADP or IDCHG to report current information to system EC.
so i want to unstuff both IADP and IDCHG 100pf decoupling…
Part Number: BQ24780S Hi Support Team members
Recenctly I receive some application issue from field.
The system designed without enabling Turbo Boost function(customer request), so we faced some AC PROCHOT issue.
Our customer running heavy loads…
Part Number: BQ24780S For BATOVP,there is such description in BQ24780S datasheet" such as when the load is removed or the battery is disconnected", how can I understand this condition?
Why will charger buck output voltage go higher when battery is removed…
Part Number: BQ24780S
1,Is BQ24780S PROCHOT# functionality only be enabled in HPB mode? Can it be enabled with adatper present only? Can it be enabled with battery present only?
2, If BQ24780S PROCHOT# functionality can be used with battery present…
Part Number: BQ24780S 1,As we know BQ24780S IADP pin is used for getting the discharging current (Vsrp<Vsrn), what's the behavior if the BQ24780S is charging the battery with Vsrp>Vsrn? Will the 0x3B bit11 EN_IDCHG be reset to 0 automatically to disable…
Part Number: BQ24780S Other Parts Discussed in Thread: BQ25798 , TPS25948 Dear TI Engineer,
Can BQ24780S support a dual battery charging solution? The number of two battery strings is the same, both are 4-cell battery pack, and the battery parameters…
Part Number: BQ24780S
1, From the BQ24780S datasheet,BATPRES# pin is just used for LEARN mode and HPB mode,how should I connect this pin if both of them have been disabled?
2, If I don't use either LEARN mode or HPB mode,should I pull BATPRES# low…
Part Number: BQ24780S 1,If I have disabled LEARN Mode and HPB Mode, will the battery charging still be disabled when I pull BATPRES# from LOW to HIGH?
2,If I have disabled LEARN Mode and HPB Mode, will the battery charging still be disabled when I pull…
Part Number: BQ24780S When battery VBAT is pulled to GND for ever, BQ24780S will just shuts down the charger converter to seperate battery short condition from VSYS to protect adapter and VSYS, and does not turn off ACFET and RBFFET, and will never resume…
