Part Number: BQ25302 Tool/software: Hello all,
We're considering using BQ25302 with VSYS feature ( via Q4 as shown in 9.2.2, figure 9-6).
I have some doubt: Q4 is a PMOS. Assuming battery is fully charged (4.2V),when no VBUS is given, i have Q4…
Part Number: BQ25570 Other Parts Discussed in Thread: BQ25302 Tool/software: Hello. I'm designing solar charging using BQ25570 and USB connection circuits using BQ25302. The LOAD I wanted to use exceeded 100mA, so I connected the load directly to the…
Part Number: BQ25302 Tool/software: Hi there,
The BQ25302 is disabled when /EN is pulled high. This disables the charger functionality and can be used to reset a fault condition.
Is Q1 (input FET from VBUS to PMID) also disabled when /EN is high?…
Part Number: BQ25302 Tool/software: Hi Team,
We have a design requirement as below.
Cell: 8.4V/1100mAh
Sys: 5V/6A=30W
May I check with you if reverse-blocking FET can sustain 5V/6A power when system is supply through VBUS?
Part Number: BQ25302 Tool/software: Hi
We are using the BQ25302 in a setup similar to the one in the datasheet:
The difference is that we are using REGN to switch Q4. Our charging current is 1A.
When we unplug the USB connector, VBUS and REGN…
Part Number: BQ25302 Hello guys,
One of my customers is considering using BQ25302 for their new products.
At this moment, they have the following question. Could you please give me your reply?
Q. When BQ25302 which set to ICHG=2A is connected to…
Part Number: BQ25302 Tool/software: Hello.
I am modifying the behavior of my charging station that uses the BQ25302 so that when a battery is removed, the IC's EN pin is pulled low, turning off the IC. On the IC, I pull POL to ground to allow this.…
Part Number: BQ25302 Other Parts Discussed in Thread: LMR36015 Tool/software: Hi everyone, I mounted the BQ25302 charger on a 4-layer PCB. It is a handheld device equipped with a single lithium polymer cell.
During the usual CE EMC measurements in the…
Part Number: BQ25302 hello. I implemented it as shown in the picture below, referring to "9.2.3 Typical Application with MCU Programmable Charge Current" in the datasheet.
I expected it to work like the truth table below, but it doesn't work properly…
