3.0
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
3.1
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.
3.2
Either 2°C (GND) or 10°C (V
selected by connecting HYST to GND or V
3.3
A 100 pF or greater decoupling capacitor from V
GND is recommended.
3.4
The voltage at the T
level if the sensor detects a temperature that is greater
than the factory-programmed threshold temperature.
Because this is an open-drain output, an external pull-
up resistor is required (a 100 k
recommended). The voltage on this pin can be higher
than V
absolute maximum input voltage of 7.0V.
