ADP194

Data Sheet FEATURES Low RDSON of 80 mΩ at 1.8 V Low input voltage range: 1.1 V to 3.6 V 500 mA continuous operating current Built-in level shift for control logic that can be operated by 1.2 V logic Low 2 μA (maximum) ground current Ultralow shutdown current <0.7 μA Reverse current blocking Ultrasmall 0.8 mm × 0.8 mm × 0.5mm, 4-ball, 0.4 mm pitch WLCSP APPLICATIONS Mobile phones Digital cameras and audio devices Portable and battery-powered equipment GENERAL DESCRIPTION The ADP194 is a high-side load switch designed for operation from 1.1 V to 3.6 V and is protected against reverse current flow from output to input. This load switch provides power domain isolation for extended power battery life. The device contains a low on-resistance P-channel MOSFET that supports more than 500 mA of continuous load current and minimizes power loss. The low 2 μA (maximum) ground current and ultralow shutdown current make the ADP194 ideal for battery-operated Logic Controlled, High-Side Power Switch ADP194 TYPICAL APPLICATIONS CIRCUIT ADP194 VIN + – GND REVERSE POLARITY PROTECTION VOUT EN ON OFF LEVEL SHIFT AND SLEW RATE CONTROL LOAD Figure 1. 08629-001 portable equipment. The built-in level shifter in the enable logic input makes the ADP194 compatible with modern processors and GPIO controllers. Beyond operating performance, the ADP194 occupies minimal printed circuit board (PCB) space with an area of less than 0.64 mm2 and a height of 0.50 mm. The ADP194 is available in an ultra...
