Product Overview: AP2162AFGEG-7

The AP2162AFGEG-7 from Diodes Incorporated is a high-performance, dual-channel current-limited power switch designed for USB and other hot-swap applications. This integrated circuit (IC) provides protection to systems and loads which may encounter dangerous current levels due to accidental short circuits or excessive load conditions.

Key Features

• Current Limiting: Each channel of the AP2162AFGEG-7 is capable of limiting the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold.
• Over-Temperature Protection: The device includes an over-temperature protection feature that shuts down the output if the die temperature rises above a preset threshold, preventing thermal runaway.
• Reverse Current Blocking: This power switch prevents reverse current flow from output to input when the device is powered off, thereby protecting the upstream devices from potential damage.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the power switch remains off when the input voltage falls below a certain threshold, which helps prevent erratic operation during low supply conditions.
• Fast Response Time: The AP2162AFGEG-7 features fast response times to fault conditions, quickly protecting the circuit by turning off the output.

Applications

The AP2162AFGEG-7 is ideal for a wide range of applications where power distribution and load protection are critical. Its typical applications include:

• USB ports and peripherals
• Hot-swap supplies
• Portable electronic devices
• Power distribution switches

Package and Quality

The device is offered in a small 8-pin SOP package, which is suitable for space-constrained applications. The AP2162AFGEG-7 is also RoHS compliant and adheres to the highest quality standards set by Diodes Incorporated, ensuring reliability and performance consistency across various conditions.

With its robust protection features and compact form factor, the AP2162AFGEG-7 is an excellent choice for designers looking to enhance the safety and durability of their USB interfaces and power distribution systems.
