Notes
11. This parameter is achieved by the design characterization by measuring a statistically relevant sample size across process variations
but, not tested in production.
12. Output OFF Open Load Detection Current is the current required to flow through the load for the purpose of detecting the existence of
an open load condition when the specific output is commanded OFF.
