Part Number: BQ25185 Hi,
I use the BQ25185 in my design. I noticed that the charger is sometimes entering factory mode :
After power up with 4.2V on VBAT, no voltage on VBUS_IN, the VSYS is measured at 1.3V, while we expect voltage >4V.
I suspect…

Hi,
I'm building a small battery charger circuit with 3v3 output so that i can run an ESP32 on solar/battery.
I'll be using a simple S1 lipo or 18650 cell. The solar panels i'd like…
Part Number: BQ25185 Hi TI team,
Schematic as shown below
Everything is working normally, and the charging current is exactly as I designed.
Initially, I only used a fixed 10k resistor at the TS/MR pin, but now I'm using a 10k/1% NTC resistor with…
Part Number: BQ25185 Hi,
Im designing a solar powered battery charger using the BQ25185 controller. The charger is connected to device that monitors data and sends it via. a 4G connection. The problem im having is that when i have an external 12V 0…
Part Number: BQ25185 Dear reader,
I have 5 PCBs with the BQ25185 connected as below.
All 5 have the same problem.
The STAT1 and STAT2 leds are both off. According to page 19 of the datasheet, this can mean several things: "Non-recoverable…
Part Number: BQ25185 Other Parts Discussed in Thread: BQ25188 Hi,
in section 7.3.8 of the datasheet it states factory mode is initiated when Vin is present and TS/MR is pulled low for tlpress, then entered on the removal of Vin There is no mention of…
