Other Parts Discussed in Thread: BQ25120

Hi,

I'm developing a design with PMIC charger BQ25120.

The battery cell I'm using does not provide NTC for Temperature control.

In order to disable the Temperature control could I short pin TS with pin IN ? Is this correct ?

Sincerely yours,

Gabriele

Hi Gabriele,

I have moved your post to the battery management.

Fisoli,

I would recommend a resistor divider of 60% (or higher) with large resistor values(100's of k). This will help with minimizing any transients you could observe on the VIN side affecting TS pin.

I've used 100K to VIN and 215K to GND.

Thank you.
