ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: The minimum operating voltage is 2.75V; however, the MAX792R and MAX820R are guaranteed to operate down to their
Note 2: Pulling RESET IN/INT below 60mV selects internal threshold mode and connects the internal voltage divider to the reset
Note 3: The Chip-Enable Propagation delay is measured from the 50% point at CE IN to the 50% point at CE OUT.
