Notes:
10. These parameters, although guaranteed, are not 100% tested in production.
11. Pulse test: pulse width 300ìs, duty 2%.
12. When activated, the output is disabled and the latch is turned off.
13. The threshold temperature for enabling the output again and resetting the latch after over-temperature
protection has been activated.
14. These parameters, although guaranteed, are tested in wafer process.
