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