The ADP195 is a high-side load switch designed for operation between 1.1 V to 3.6 V and protected against reverse current flow from output to input. This load switch provides power domain isolation helping extended power domain isolation. The device contains a low on-resistance, P-channel MOSFET that supports over 500 mA of continuous current and minimizes power loss. The low 1 μA of quiescent current and ultralow shutdown current make the ADP195 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP195 compatible with many processors and GPIO controllers.
In addition to operating performance, the ADP195 occupies minimal printed circuit board (PCB) space with an area of less than 1.0 mm2 and a height of 0.60 mm.
It is available in an ultrasmall 1 mm × 1 mm, 4-ball, 0.5 mm pitch WLCSP. A 6-lead 2 mm × 2 mm × 0.55 mm, 0.65 mm pitch LFCSP is also available.

Evaluation Kits (2)
The ADP195-EVALZ and ACP195CP-EVALZ are used to demonstrate the functionality of the ADP195 power switch. Simple device measurements such as VIN to VOUT resistance (RDSON), ground current, and off state current can be demon-strated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
This evaluation board is obsolete and no longer recommended. For more information visit ADI EagleEye™.
The Blackfin Low-power Imaging Platform (BLIP) is a low cost, low power embedded computer vision platform targeting a vast array of real-time sensing applications. BLIP leverages the latest entry within the industry-leading, low power Blackfin processor family as well as Analog Devices’ optimized software library deliverables. This solution offers end equipment manufacturers an out of the box form factor development platform with multiple functional profiles covering intelligent motion sensing, people counting, vehicle detection, and face detection deployable in both indoor and outdoor use cases. The BLIP system includes an intuitive configuration GUI and enables real-time analysis of captured video, as well as video output/display through an on-board USB port, making it a highly valuable tool for product development. Additionally, the associated documentation package is well positioned to help customers accelerate their time to market.
