The AOZ1363 high current smart load switch features rapid turn-off fault protection and current monitoring. The device has an operating input voltage range from 5 to 16 V and is capable of supplying up to 6 A of continuous current. A low on-resistance of 23 mΩ in a thermally enhanced 3 x 3-mm DFN package makes suitable for space-constrained applications that require circuit protection such as the latest notebook PCs, hot swap supplies and micro servers.
The load switch features an internal current limiting circuit in conjunction with a thermal protection function that limits excessive power dissipation. Externally programmable soft-start circuitry controls inrush current from highly capacitive loads during hot-plug events. The device can communicate load information in real time through the current monitoring pin (ISEN ) with an accuracy window of 10% at a specified load current of 3 A. The load switch detects over-current fault conditions and executes a power-down within a delay time of 100 ns maximum.
