ACE345
Adjustable USB Load Current Switch
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 150μA, 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

Adjustable USB Load Current Switch
Current limiting
The current limit ensures that the current through the switch doesn't exceed a maximum value while not
limiting at less than a minimum value. The current at which the parts will limit is adjustable through the
selection of an external resistor connected to ISET. Information for selecting the resistor is found in the
Application Info section. The ACE345 has no current limit blanking period so it will remain in a constant
current state until the ON pin is deactivated or the thermal shutdown turns-off the switch.
Thermal Shutdown
The thermal shutdown protects the die from internally or externally generated excessive temperatures.
During an over-temperature condition the switch is turned-off. The switch automatically turns-on again if
temperature of the die drops below the threshold temperature.
