Description

The ACE345 is Adjustable USB Load Current Switch Current Limited designed for high-side load

switching applications. The internal current-limiting circuit protects the input supply against large output

short circuit current which may cause the supply to fall out of regulation.

The current limit threshold is programmed with an external resistor from ISET Pin to ground. The

quiescent supply current is typically 150

μA, making the device ideal for portable battery-operated

equipment. In shutdown mode, the supply current decreases to less than 0.1μA.

Additional features include thermal shutdown and constant current output characteristics if current

exceed its current limit
