Introducing the AP22818AKAWT-7 Power Switch from Diodes Incorporated

The AP22818AKAWT-7 is a high-performance, single channel current-limited integrated high-side power switch from Diodes Incorporated, designed for USB and other hot-swap applications. This advanced power management IC is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

With a 5.5V tolerant active high enable input, the AP22818AKAWT-7 is capable of delivering an output current of 2A, making it suitable for a wide range of applications that require a robust power distribution and protection system. Its low on-resistance of 92mΩ ensures high efficiency and minimal voltage drop across the switch, thereby providing a stable power supply to the load.

The device is equipped with a range of protective features to ensure the safety and reliability of connected devices. These include over-current protection (OCP), over-temperature protection (OTP), under-voltage lockout (UVLO), and reverse current blocking. The over-current protection mechanism is designed to protect the device and the load from excessive current that could cause damage. Additionally, the AP22818AKAWT-7 has a fast short-circuit response time of less than 1µs, which is critical for preventing damage due to sudden and severe over-current conditions.

Another key feature of this power switch is its controlled rise time, which reduces inrush current and minimizes the impact on the power source, especially important in USB applications. The device also includes an auto-retry feature, which allows it to attempt to restart after a fault condition has been removed, providing a self-recovery capability that enhances system robustness.

The AP22818AKAWT-7 comes in a small footprint package, the SOT-25, which is ideal for space-constrained applications. The compact size, combined with its high level of integration, makes it an excellent choice for portable electronics, including smartphones, tablets, and other USB peripheral devices.

Overall, the AP22818AKAWT-7 from Diodes Incorporated is a versatile and reliable power switch that offers both protection and power management functionalities, ensuring the safe and efficient operation of USB interfaces and other applications requiring current-limited power distribution.
