The AP2181AS-13 from Diodes Incorporated is a high-performance, single-channel current-limited integrated power switch designed for USB and other hot-swap applications. This power switch is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications, offering a compact and efficient solution for managing power distribution and protection in a variety of systems.

With an input voltage range of 2.7V to 5.5V, the AP2181AS-13 is versatile and can be used in a broad spectrum of USB peripherals and other portable devices. It is capable of delivering up to 1.0A of continuous current, which makes it suitable for handling standard USB loads. The switch is also equipped with fast short-circuit response time, typically 3μs, ensuring quick protection for the device in the event of a fault condition.

The AP2181AS-13 features built-in over-current protection (OCP) to safeguard the device and the load from excessive current that could cause damage. Furthermore, the switch includes thermal shutdown protection (TSD) which prevents overheating by automatically turning off the power switch if the junction temperature exceeds the thermal shutdown threshold.

This power switch also incorporates under-voltage lockout (UVLO) that ensures the switch remains off if the input voltage drops below a specified threshold, thus protecting the circuit from unstable operation. The device offers a controlled rise time to reduce inrush current, which is particularly beneficial in preventing glitches on the power line that can cause collateral issues in sensitive electronics.

The AP2181AS-13 comes in a space-saving SOT-25 package, making it an excellent choice for space-constrained applications. It is also RoHS compliant, reflecting Diodes Incorporated's commitment to environmentally responsible manufacturing. With its built-in protection features and compact design, the AP2181AS-13 is an ideal power management solution for a wide range of applications where reliable power distribution and circuit protection are essential.
