FUNCTION
Control Input for Switch A. Can be driven higher than IN_ without damage. A logic low turns switch A on for
the MAX1823/MAX1823A, and a logic high turns switch A on for the MAX1823B/MAX1823H.
Power Input. Connect all IN_ pins together, and bypass with a 0.1μF capacitor to ground. Load
conditions may require additional bulk capacitance to prevent the input from being pulled down.
Control Input for Switch B. Can be driven higher than IN_ without damage. A logic low turns switch B
on for the MAX1823/MAX1823A, and a logic high turns switch B on for the MAX1823B/MAX1823H.
Fault-Indicator Output for Switch B. This open-drain output goes low when switch B is in thermal
shutdown or UVLO or in a sustained (>20ms) current-limit or short-circuit condition.
Power Output for Switch B. Connect a 1μF capacitor from OUTB to ground. Load condition may
require additional bulk capacitance.
Ground
Power Output for Switch A. Connect a 1μF capacitor from OUTA to ground. Load condition may
require additional bulk capacitance.
Fault-Indicator Output for Switch A. This open-drain output goes low when switch A is in thermal
shutdown or UVLO or in a sustained (>20ms) current-limit or short-circuit condition.
* () are for the MAX1823B/MAX1823H only.
