The device’s two N-channel MOSFET outputs can be independently controlled, with slew rates set via ground-connected external capacitors on its soft-start inputs. A logic-high signal applied to the channel-enable pins produces output voltages that increase gradually and linearly, thereby limiting circuit inrush current. The AP22966 is housed in a small form factor, exposed-pad DFN3020 package, which offers a PCB footprint of 6mm².
The AP22966 load switch operates over 0.8V to 5.5V input. This device is also characterised by very low quiescent currents (60 µA for both channels and 45 µA for single-channel). It costs $0.085 (1,000).
