Introducing the AP2191 Single Channel Current-Limited Power Switch

Diodes Incorporated presents the AP2191, a high-performance, single channel current-limited integrated power switch designed for USB and other hot-swap applications. This compact and efficient device is tailored to meet the stringent requirements of power management and protection for modern electronics.

Key Features

• Current Limiting: The AP2191 offers an adjustable current limit function, which is essential for preventing damage to host devices due to overcurrent conditions. This feature enhances system reliability and ensures safe operation under varying load conditions.
• Fast Response Time: With a quick response to fault conditions, the AP2191 minimizes the risk of system failure. Its built-in circuitry is designed to react rapidly to overcurrent, overtemperature, and short-circuit scenarios.
• High Accuracy: The device provides high accuracy in current limiting, ensuring precise control over the power supplied to downstream components, which is crucial for sensitive electronics.
• Reverse Current Blocking: In the event of a power failure or when the switch is turned off, the AP2191 prevents reverse current flow, protecting the source from potential damage.
• Low Power Consumption: Optimized for energy efficiency, the AP2191 features a low quiescent current, which reduces the overall power consumption of the system, making it suitable for battery-powered applications.
