AP2331TDW-7

Overview

The AP2331TDW-7 is a single-channel high-side power switch IC manufactured by Diodes Incorporated, designed for USB power distribution applications. It operates within a supply voltage range of 2.7 V to 5.2 V and features a maximum on-resistance of 350 mOhms. The device provides an output current capability of 200 mA with a current limit set at 400 mA. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a compact SC-59-3 surface-mount package.

Feature Summary

• Integrated current limiting protection mechanism
• High-side load switching configuration
• USB power distribution compatibility

Applications

• USB port power switching
• Peripheral power distribution
• Load switching in portable electronics

Procurement Notes

Verify the specific suffix 'TDW' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel specifications. Ensure the ordering information matches the required SC-59-3 form factor. Cross-reference the RoHS compliance status directly with the latest product documentation provided by Diodes Incorporated before finalizing procurement orders.

Selection Notes

Select this component when a single-channel high-side switch with integrated current limiting is required for low-voltage logic interfaces. The 350 mOhm on-resistance suits applications where moderate conduction loss is acceptable. Verify that the 200 mA continuous output current meets the load requirements and that the 400 mA limit provides adequate fault protection margin for the specific circuit design.

Part Context

This part belongs to the AP2331 series of power switches from Diodes Incorporated. The series includes variants such as AP2331SA-7 which utilizes an SOT-23-3 package. These devices are categorized under Power Switch ICs for power distribution, offering similar electrical characteristics but differing in physical footprint and thermal performance based on the selected package style.

Replacement Considerations

AP2331SA-7 offers identical electrical specifications but uses an SOT-23-3 package instead of SC-59-3.
