The ever-increasing portable-computing market continues to demand more integrated and capable load switches. These are required for distributed power control and low-voltage differential signalling where switches rated for continuous output-current operation with power-good indication and adjustable discharge are key. These functions and performance are delivered cost-effectively by the AP22850, which is based on a P-channel MOSFET that has a low typical RDS(ON) of 20mΩ. The device can handle inputs up to 12V with a maximum output current of 8A but with a quiescent (no-load) current of just 1.2nA.
The AP22850 does not require an external gate pull-up resistor and integrates circuitry to suppress fast input transients from coupling to the output; these features contribute to reduced BOM costs and board area savings. It is offered in the space-saving, thermally efficient 2x2x0.8mm W-DFN2020-8 package, maximising available board space.
The AP22850 is available now for $0.08 each in 1,000 unit quantities.
