Part Number: BQ24308 Hi
The customer design with BQ24308.
At the beginning, when Vin >= 5.1V, Vout will not be able to pull up always, it is pulled Low immediately, repeating all the time.
When use Vin<=5V, Vout output is normal. At this time, increase…
Hi Aziz,
Have you seen this document? https://www.ti.com/lit/ug/sluu291b/sluu291b.pdf See Page 12 where is shows which PFET is used. It uses a 100k pullup resistor on the PGATE pin also. I am not sure what happens if PGATE is left floating (the designer…
Part Number: BQ24308 Hi,
I've two questions pertaining BQ24308:
1. In datasheet pg 6, High-level input voltage V(IH) of CE stated the min spec is 1.4V. Does that mean that it requires at least 1.4V to enable the device? Customer of mine encountered…
Part Number: BQ24308 Hi,
I'd like to seek for your advise on the value of tDGL
In my customer application, they have added a reset circuit to control "CE" pin of BQ24308. As a result, we need to have a detail specification on tDGL(PGOOD)…
Hi Andria,
Thanks.
We realized that it is probably the counter reaching 15 times of OCP...
Anyway, we ordered a similar chip to test, the BQ24308; hopefully this will solve our case.

Yoav
Other Parts Discussed in Thread: BQ24308 Hi Everyone,
Please let me ask about Ron of internal Q1 FET of bq24308. The VDO at 250mA is specified as 75mV max, so I understand that the Ron max at 250mA should be 300mohm. Then is it also the same at 1.5A ?…
Part Number: BQ24314C Other Parts Discussed in Thread: BQ24308 Hi,
In the datasheet it specifies the the recommendeed operating conditions are:
But then in the appendix 9 it says:
It seems contradictory and misleading. Will my application works if I…
Hi Given, I think there is a typo above about Iout. Please correct. We have several charger front end ICs like BQ24308 or BQ24380 or BQ24351 which could be interesting devices for this project but need the correct Iout to be specified to confirm.
