The ADP1196 from Analog Devices is a Logic Controlled High-Side or Low-Side Load Switch that is ideal for communications and infrastructure, thermoelectric cooler (TEC) controller reverse polarity for heating and cooling, fine line geometry core voltage inrush current control, medical, healthcare and instrumentation applications. This switch requires an input voltage of 1.83 – 5.5 V and a continuous input current of 3 A. It integrates an internal charge pump that allows it to drive a very low on-resistance N-channel MOSFET. This power switch has a low quiescent current and ultralow shutdown current making it an ideal solution for low-power applications. It features over-temperature protection circuitry, thereby protecting the switch and the downstream circuits from potential damage. This power switch is available in a wafer package that measures 1.0 x 1.5 x 0.5 mm.
