## Description

This compact Adafruit breakout helps manage two power inputs in a small project, such as a battery, USB supply or DC wall adaptor. It uses the LM66200 dual ideal diode IC to select the higher of two inputs while helping prevent back-powering.Connect your two 2–5V supplies to Vin1 and Vin2, and the selected supply appears on Vout. You can disable the output by pulling the On/Enable pin high, and use the Status pin to check whether Vin1 or Vin2 is currently selected.For easy prototyping, the board has 6 x 0.1" breakout pads and includes a bit of header. The chip and a 1 Megaohm enable-pulldown are already fitted; light soldering is required to attach the header, or you can wire it directly into your circuit.Specifications:Product information: LM66200 Product information pageInput voltage range: 1.6 V to 5.5 VMaximum continuous current: 2.5 AOn-resistance: 40 mΩ (typical)Standby current: 50 nA (typical)Quiescent current: 1.32 μA (typical)Automatic diode switchover: Automatic diode switchoverControlled output slew rate: 1.3 ms (typical) at 3.3 VReverse current blocking: Reverse current blocking when VOUT > VINxThermal shutdown: Thermal shutdownProduct Dimensions: 16.5mm x 10.0mm x 2.2mm / 0.6" x 0.4" x 0.1"Product Weight: 0.5g / 0.0ozA handy power-path building block for battery-backed gadgets, USB-powered prototypes and compact circuits that need low-drop dual-supply switchover.
