AP2141DFMG-7

Overview

The AP2141DFMG-7 is a single-channel high-side power switch IC designed for USB 2.0 applications, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers a continuous output current of 500 mA with a fixed current limit of 800 mA. The device features a maximum on-resistance of 110 mOhms, ensuring efficient power distribution. Switching times are specified at a maximum of 50 us for both turn-on and turn-off durations. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a compact UDFN-6 surface-mount package.

Feature Summary

Single-channel high-side power switching architecture optimized for USB 2.0 port protection
Integrated fixed current limiting capability to safeguard downstream loads
Low on-resistance design minimizes power loss during conduction
Fast switching response supports rapid power sequencing requirements

Applications

USB 2.0 hub power distribution circuits
Portable electronic device power management
Consumer electronics peripheral power switching
Industrial control board I/O power isolation

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm RoHS compliance status through official documentation prior to integration. Cross-reference the datasheet revision date to validate parameter accuracy against current manufacturing standards. Ensure ESD handling protocols are followed during assembly due to the small form factor.

Selection Notes

Select this component when a single-channel solution with moderate current capacity is required for USB interfaces. The low on-resistance makes it suitable for applications prioritizing efficiency over higher current ratings. Consider the UDFN-6 package constraints for PCB layout space. Evaluate thermal performance under continuous load conditions given the limited heat dissipation area of the package.

Part Context

This device belongs to the AP2141 series of power switches from Diodes Incorporated. The series provides various channel configurations and current ratings for different power distribution needs. The AP2141DFMG-7 specifically addresses single-channel applications requiring precise current limiting and fast switching characteristics within standard USB voltage ranges.
