Note 1: MAX1693’s current limit is tested by forcing V_OUT to 4.5V. The MAX1694’s current limit is tested by increasing the output cur-
rent until the switch is latched off.
Note 2: This specification applies to the MAX1693 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.
