The AP2191DWG-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 compact and efficient device is housed in a small SOT-25 package, making it an ideal choice for space-constrained applications.

With an input voltage range of 2.7V to 5.5V, the AP2191DWG-7 is optimized for operation in a variety of systems, supporting the common voltage rails found in consumer electronics, industrial controls, and portable devices. Its low quiescent current and standby current make it an energy-efficient solution for battery-powered applications.

This power switch features a fast transient response, which provides reliable protection for the host device by limiting the amount of current during an over-current event. The built-in current limit is set at 1.2A, which helps prevent damage to the USB port and connected devices. Additionally, the AP2191DWG-7 incorporates thermal shutdown protection to safeguard against excessive temperature rises.

The device offers a controlled rise time to reduce inrush current, minimizing the impact on the power source and other circuitry. It also includes under-voltage lockout (UVLO) to ensure that the power switch operates only when the input voltage is within an acceptable range, enhancing system reliability.

The AP2191DWG-7 has an active-high enable feature, allowing the power switch to be controlled via a simple logic signal. This enables easy integration into a system's power management scheme, providing designers with flexibility in controlling the power distribution to downstream circuits.

Overall, the AP2191DWG-7 from Diodes Incorporated is a robust and versatile power management solution that offers a combination of protection features, low power consumption, and compact size, making it an excellent choice for a wide range of applications requiring efficient power distribution and circuit protection.
