Note 1: The output voltage at which the device transitions from short-circuit current limit to continuous current limit.
Note 2: Specifications to -40°C are guaranteed by design, not production tested.
Note 3: Reverse current (current from OUT_ to IN_) is blocked when disabled.
Note 4: Forward current (current from IN_ to OUT_) is internally limited. Reverse current, from OUT_ to IN_, is not limited when the
device is enabled and must be kept below 1.5A
RMS
to prevent permanent device damage. When the MAX1823A/MAX1823B
are disabled, the switch turns off and reverse current is internally blocked.
