External Temperature Sensing (TS)
The P9241-G includes an optional temperature sense input pin, TS, that is used to monitor a remote temperature, such as for a coil or a battery
charger. The TS pin voltage can be calculated using Equation 1.

Where
NTC = The thermistor’s resistance (RTH1)
R60 = The pull-up resistor connected to the 3.3V supply voltage on the P9241-G Evaluation Board
Equation 1
The over–temperature shutdown is triggered if the voltage on the TS pin is lower than 0.6V and recovers at 0.8V. The RTH1 is not populated
on the P9241-G Evaluation Board.
