Product Overview: AP2191SG-13

The AP2191SG-13 is a high-quality, single-channel current-limited integrated high-side power switch, designed and manufactured by Diodes Incorporated. This power switch is optimized for Universal Serial Bus (USB) and other hot-swap applications. It is a crucial component for systems that require power distribution and protection for USB ports, particularly in consumer electronics, computing, and communication devices.

Key Features

• Current Limiting: The device offers programmable current limiting to protect the USB port from overcurrent conditions. This feature ensures the longevity and reliability of both the port and the connected devices.
• Fast Response Time: With a fast response time to fault conditions, the AP2191SG-13 can quickly disconnect the faulty load, preventing damage to other components in the system.
• Low On-Resistance: The low on-resistance of the internal switch minimizes voltage drop and power loss, ensuring efficient power distribution to the connected device.
• Reverse Current Blocking: This feature prevents current from flowing backward into the source when the switch is powered off, further protecting the circuitry.
• Over-Temperature Protection: The built-in over-temperature protection automatically shuts down the switch to prevent overheating, which could otherwise lead to system failure.
• Controlled Rise Time: The AP2191SG-13 ensures reduced inrush current with its controlled rise time, which is particularly beneficial in sensitive applications where sudden surges can be problematic.

Product Specifications

The AP2191SG-13 is offered in a green SOT-23-5 package, which is RoHS compliant and contributes to the reduction of hazardous substances in electronic devices. It operates over a voltage range of 2.7V to 5.5V, making it suitable for low voltage applications. The switch also features an active high enable input, which allows for easy control over the power switching functionality.

Applications

With its robust feature set, the AP2191SG-13 is an ideal choice for a wide range of applications. These include USB hubs, peripheral ports, and hot-swap supplies. It's also suitable for battery-charging circuits and power management tasks where precise control and protection are paramount.

Diodes Incorporated's commitment to quality ensures that the AP2191SG-13 meets the stringent requirements of modern electronic systems, providing a reliable and efficient solution for power switching and distribution.
