Note 1: MAX1693/(MAX1693H)’s current limit is tested by forcing V
OUT
to 4.5V. The MAX1694’s current limit is tested by increasing
the output current until the switch is latched off.
Note 2: This specification applies to the MAX1693/(MAX1693H) only. The MAX1694 latches the switch off under a sustained
(>10ms) short-circuit condition.
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
