Product Overview: AP2191DSG-13-82 from Diodes Incorporated

The AP2191DSG-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 compact and efficient device is part of a family of power switches that provide advanced protection for electronic systems from excessive current, thereby ensuring the safety and reliability of the system.

Key Features

• Current Limiting: The product features an accurate and programmable current limit threshold, which is ideal for USB power distribution systems that require precise control over the power supplied to downstream devices.
• Fast Response Time: With a quick response time to fault conditions, the AP2191DSG-13-82 can prevent damage to the host device by rapidly disconnecting the faulty load.
• Over-Temperature Protection: The built-in over-temperature protection ensures that the device automatically shuts down if it exceeds the safe operating temperature range, thus preventing thermal overload.
• Reverse Current Blocking: This feature prevents current from flowing backward into the source when the switch is off, protecting the source from potential damage.
• Controlled Rise Time: The AP2191DSG-13-82 has a controlled rise time which reduces inrush current, minimizing the impact on the power source and other components in the system.
• Low Standby Current: Its low standby current consumption makes it suitable for battery-powered applications where power efficiency is critical.
