Overview of Product AP2191SG-13-82 from Diodes Incorporated

The AP2191SG-13-82 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 power switch is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Current Limiting: The device offers precise current limiting to protect the host device from over-current conditions. It is capable of delivering up to 1.0A of continuous current.
• Fast Transient Response: The AP2191SG-13-82 provides a fast transient response, which is essential for maintaining stable operations in USB applications.
• Built-in Soft-Start: It includes a built-in soft-start function that limits inrush current during plug-in events, minimizing the risk of voltage drops on the power lines that could affect other system components.
• Over-Temperature Protection: The device features an over-temperature protection mechanism that shuts down the power switch to prevent excessive heat from damaging the IC or the system.
• Reverse Current Blocking: When the switch is disabled, the AP2191SG-13-82 prevents reverse current from flowing from the output to the input, safeguarding the system against potential damage.
• High-Side Switch: As a high-side switch, it allows for the power to be turned on and off to downstream devices without the need for an external power FET.
• Green Packaging: The product comes in environmentally friendly packaging, specifically a lead-free and RoHS compliant SOP-8 package, denoted by the "-13" in its part number.
