Addendum: The problem was the mechanical structure. The interference was coupled to the supply line via the built-in Li-Ion battery. The battery almost directly touched the switching coil. I have now placed the switching coil on the edge of the circuit…
Part Number: BQ25302 Tool/software: Customer is using BQ25302RTER charger IC in their project.
When the battery cell <2.5xV, the VSUB charger can’t charge the battery cell, the indictor LED always blinking.
If the voltage above 2.8V ~ 3V,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?
The…
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 Tool/software: Good day,
I am struggling to figure out the RT1 and RT2 values based on the datasheet. the formula states:
I am trying to use an NTC thermistor 10k with beta 3435
Which makes RNTCT1 = 29.16K (@0°C) and RNTCT3 = 4…
Part Number: TPS63806 Other Parts Discussed in Thread: BQ27427 , BQ25302 Hello Team,
We are currently developing a wearable device, and I would like to request your review of the power section schematic of our system to ensure everything is correct.

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 5V/1A adapter…
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…
Part Number: BQ25302
Dear TI team,
we are developing a PCB for charging an 18650 Li-ion battery using the part BQ25302. We connected a status LED to the STAT pin to monitor the charging status.
On our first prototype, we noticed a strange behavior.…
