General Description

The AP2552/53 and AP2552A/53A are single channel precision adjustable current-limited switches optimized for applications that require precision current limiting, or to provide up to 2.1A of continuous load current during heavy loads/short circuits.

These devices offer a programmable current-limit threshold between 75mA and 2.36A (Typ.) via an external resistor.

Current limit accuracy ±6% can be achieved at high current-limit settings.
