Design a Custom BoardAbout This Component
Precision adjustable current-limited power switch with up to 2.1A continuous load current and programmable current limit (75mA to 2.36A) via external resistor. Offers fast short-circuit response (2µs typical), reverse current blocking, over-current/over-temperature/thermal protection, and soft-start functionality. Operates 2.7V to 5.5V with active-high enable and fault reporting for portable power supplies, USB protection, and load switching applications.
Package: SOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
