Push/Pull Active-High Output
Connect the device ground pins directly to the PCB
ground and minimize the length of the connection. The
thermal resistance to the die is at a minimum at Pin 2.
(TC6502) (T OVER )
The voltage at T OVER is equal to a logic-high level if the
sensor detects a temperature greater than the factory-

programmed threshold temperature.
Either 2°C (GND) or 10°C (V CC ) of hysteresis is
selected by connecting HYST to GND or V CC .

3.3 Supply Input (V CC )
A 100 pF or greater decoupling capacitor from V CC to
GND is recommended.
The voltage at the T UNDER pin is equal to a logic-low
level if the sensor detects a temperature that is less
than the factory-programmed threshold temperature.
Because this is an open-drain output, an external pull-
up resistor is required (a 100 k ? pull-up resistor is

than V CC , though the voltage must not exceed the
absolute maximum input voltage of 7.0V

The voltage at T UNDER is equal to a logic-high level if
the sensor detects a temperature less than the factory-
programmed threshold temperature.
