Design a Custom BoardAbout This Component
Ideal diode controller IC that replaces Schottky diodes in reverse polarity protection and OR-ing applications. Operates as a low-loss ideal diode using an external N-channel MOSFET to provide near-zero forward voltage drop and automatic reverse blocking. Typical applications include Anderson connector protection, solar panel arrays, and battery management systems.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
