AP2331TDSA-7

Overview

The AP2331TDSA-7 is a single-channel USB load switch and hot-swap controller manufactured by Diodes Incorporated. It operates within an input voltage range of 2.7 V to 5.2 V and features a typical on-resistance of 250 mΩ with a precise current limit of 0.4 A. The device integrates soft-start, reverse current blocking, and comprehensive protection against overcurrent, short circuits, and thermal overload. It is housed in a compact SOT-23-3 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

Integrates fast response short-circuit protection and controlled rise time for system integrity
Provides reverse current blocking and under-voltage lockout functionality
Includes built-in soft-start with typical 0.7 ms startup time

Applications

LCD televisions and display systems
Set-top boxes and residential gateways
Laptops, desktops, and servers
Printers, expansion docks, and hubs

Procurement Notes

Verify the specific suffix 'TDSA' against the official Diodes Incorporated datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the component meets RoHS compliance and halogen-free requirements as stated in the product family documentation before finalizing procurement orders.

Selection Notes

Select this component for applications requiring hot-swap capability and robust protection against high-capacitive loads or potential short circuits. The integrated reverse current blocking makes it suitable for bus-powered devices where back-feeding must be prevented. Verify that the 0.4 A current limit aligns with the target load requirements.
