AP2191DMPG-13 - Diodes Incorporated

The AP2191DMPG-13 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) and other hot-swap applications.

Key Features:

• Current Limiting: The device offers programmable current limiting to protect the host device from overcurrent conditions. It is capable of delivering up to 2A of continuous current, making it suitable for a wide range of peripherals.
• Fast Transient Response: With its fast transient response, the AP2191DMPG-13 is able to handle quick changes in load conditions without compromising the stability of the application.
• Reverse Current Blocking: This feature prevents current from flowing backward through the switch when it is powered off, thereby protecting downstream components.
• Over-Temperature Protection: The power switch includes an over-temperature protection mechanism that shuts down the output to prevent damage from excessive heat.
• Controlled Rise Time: The AP2191DMPG-13 incorporates a controlled rise time to reduce inrush current, which helps to minimize electromagnetic interference (EMI).
• Low Standby Current: The device has a low standby current, which is crucial for power-sensitive applications.
• Input Voltage Range: It operates over an input voltage range of 2.7V to 5.5V, making it versatile for various USB applications.

Applications:

• USB Peripherals
• Hot-Swap Supplies
• Portable Devices
• Battery-Charger Circuits
• Notebook Computers

The AP2191DMPG-13 comes in a small 6-pin DFN package, which is RoHS compliant and halogen-free, ensuring environmental sustainability while providing a compact solution for space-constrained applications.
