NOTES: 11. Adjust VCC above the start–up threshold before setting to 12 V. Low duty cycle pulse techniques are used during test to maintain junction
NOTES: 11. temperature as close to ambient as possible.
12. This function can be inhibited by connecting pin 1 to GND.
13. Guaranteed by design (non tested)
