BQ24045: question about the TS terminal.

Part Number: BQ24045

I have a question about the TS terminal.

I connected the thermistor from the TS terminal to Vss to use the TS function.

And I want to use two additional functions.

But I don't know how to pulled low or driven high on the TS terminal.

Just give a high or low signal to the TS terminal?

I want to know the hardware connection.

    Hi Min Woo,

    TS pin can be pulled to GND by means of an external NMOS in parallel with your thermistor. The NMOS can be turned on and off by using high/low signal from your MCU. 

    You can also float this pin by connecting an external MOSFET in series with the thermistor.
