AP2331W-7

Overview

The AP2331W-7 is a load switch IC from the AP2331 series manufactured by Diodes Incorporated. It features one input and five outputs with an operating current of 0.2 A. The device supports an input voltage range from 2.7 V to 5.2 V and has an on-resistance (RdsOn) of 350 mΩ. It is housed in a surface-mount SC-59 package with three pins, measuring 3.1 mm in length, 1.7 mm in width, and 1.3 mm in height. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates five independent output channels for multi-rail power distribution management
• Provides low on-resistance switching capability for efficient power delivery
• Supports wide input voltage operation suitable for various logic levels

Applications

• Multi-rail power sequencing in portable electronic devices
• Load management for peripheral circuits in consumer electronics
• Power distribution networks requiring multiple switched outputs

Procurement Notes

Verify the specific suffix 'W-7' against the manufacturer's official datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure the SC-59 package dimensions align with your PCB footprint requirements. Confirm that the 350 mΩ on-resistance meets your voltage drop constraints under the maximum 0.2 A load current. Check for any RoHS or REACH compliance documentation required for your region.

Selection Notes

Select this component when a single IC solution is needed to manage five separate power rails simultaneously. The SC-59 package offers a compact form factor for space-constrained designs. Consider the 350 mΩ on-resistance impact on efficiency if higher currents are anticipated. Verify that the 2.7 V minimum operating voltage matches your system's lowest supply rail during brown-out conditions.

Part Context

The AP2331W-7 belongs to the AP2331 family of load switches designed for power distribution applications. This series focuses on integrating multiple switches into a single small package to reduce board space and simplify design. Unlike general-purpose analog switches, these devices are optimized for managing power rails with specific control logic interfaces and protection features typical of load management ICs.

Replacement Considerations

Consult the manufacturer's official cross-reference list for verified substitutes. Ensure any replacement maintains the five-output configuration and compatible SC-59 or equivalent footprint. Verify that alternative parts support the same 2.7 V to 5.2 V input range and meet the 0.2 A current requirement.
