I would like to use the BQ2057C Li-ion charger. Its nice thats its a SOIC package so its easy to solder, and use a external mosfet so i can get a good 1A with no trouble.
Most IC for Li-ion let you disable the temp sensor using a 10K pull down resistor.
I require to disable the temp sensor as my Li-ion cells do not have a connection for this as it down with a protection PCB which is packaged with the cell.
Now according to the datasheet
It says it can be disabled and would work for only one temperture , hot or cold. So what would be hot and what would be cold?
Applying a voltage between
the V(TS1) and V(TS2) thresholds to pin TS disables the temperature-sensing feature.
So do i still use the voltage devider circuit? Or can i just use one resistor and then use the formulas to determin the value.
I would greatfull if someone could tell me what is hot and cold, so i can choose the right values.
If only one resistor is required and that being the connected to gnd, which formula do we use as there is NTC and PTC.
