3.0
TABLE 3-1:
3.1
The GND pin is the system ground pin. Pin 2 must be
connected to system ground. Pin 1 can also be
connected to system ground which would provide
better thermal conduction to the die.
3.2
This is an input pin which can be connected to V
GND
(HYST = GND) or 10°C (HYST = V
hysteresis can be selected.
