NOTE 2 : Adjust VCC above the start–up threshold before setting to 12 V. Low duty cycle pulse techniques are used during test to maintain junction
temperature as close to ambient as possible.
NOTE 3 : This function can be inhibited by connecting pin 1 to GND.
NOTE 4 : Guaranteed by design (non tested).
