Design a Custom BoardAbout This Component
High-side current-limited load switch optimized for hot-swap applications in 2.7V to 5.2V systems. Features 0.4A current limiting, 250mΩ on-resistance, and comprehensive protection including reverse-current blocking, overcurrent, overvoltage, short-circuit, and thermal shutdown. Ideal for USB ports, power rails, and peripherals in consumer electronics.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
