Design a Custom BoardAbout This Component
High-side power switch for USB and hot-swap applications with 1.5A current limiting and 95mΩ on-resistance. Features overcurrent/thermal protection, reverse current blocking, 7ms fault deglitch, and operates from 2.7V–5.5V. Includes active-low enable, low shutdown current (1µA max), and 4kV ESD protection; suitable for consumer electronics, communications, and computing applications.
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.
