APPLICATIONS Mobile phones Digital cameras and audio devices Portable and battery-powered equipment GENERAL DESCRIPTION The ADP197 is a high-side load switch designed for operation between 1.8 V and 5.5 V. This load switch provides power domain isolation, helping extended power domain isolation. The device contains a low on-resistance, N-channel MOSFET that supports more than 3 A of continuous current and minimizes power loss. The low 18 μA quiescent current and ultralow shutdown current make the ADP197 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP197 compatible with many processors and GPIO controllers. Overtemperature protection circuitry activates if the junction temperature exceeds 125°C, thereby protecting itself and downstream circuits from potential damage. In addition to operating performance, the ADP197 occupies minimal printed circuit board (PCB) space with an area of less than 1.5 m...
