Product Overview: AP2191DMPG-13-02 from Diodes Incorporated

The AP2191DMPG-13-02 is a high-quality, single-channel current-limited integrated high-side power switch, designed and manufactured by Diodes Incorporated. This device is optimized for Universal Serial Bus (USB) and other hot-swap applications. It is built to offer protection to systems and USB ports by limiting the amount of current that can be drawn by a connected device.

The AP2191DMPG-13-02 operates over a voltage range of 2.7V to 5.5V, making it suitable for a variety of low-voltage applications. It is capable of delivering up to 1A of continuous current, ensuring that it can support most USB peripherals. Additionally, it features fast short-circuit response time, which is critical for preventing damage to the USB port and connected devices in the event of a fault.

With built-in thermal shutdown, the device also provides reliable protection against overheating. If the junction temperature exceeds the thermal shutdown threshold, the power switch will turn off, thereby safeguarding the IC and the system from thermal damage. Once the device has cooled down to a safe operating temperature, it will automatically restart operation.

The AP2191DMPG-13-02 is also equipped with controlled rise time and under-voltage lockout functionality, which reduces inrush current and prevents the system from operating at sub-optimal voltages, respectively. These features contribute to the stability and reliability of the system.

This power switch comes in a small 6-pin DFN2020 package, which is space-efficient and ideal for compact designs. Its RoHS compliance ensures that it meets the latest environmental standards, minimizing the ecological impact.

In summary, the AP2191DMPG-13-02 from Diodes Incorporated is a versatile and reliable power switch that provides current limiting, thermal shutdown, and under-voltage lockout features. Its compact size and compatibility with USB applications make it an excellent choice for designers looking to enhance the safety and durability of their systems.
