AP2141FMG-7

Overview

The AP2141FMG-7 is a high-side power distribution switch manufactured by Diodes Incorporated. It features one output channel with a maximum continuous output current of 0.5 A and a fixed current limit of 800 mA. The device operates within a supply voltage range of 2.7 V to 5.5 V and exhibits a maximum on-resistance of 110 mOhms. Switching characteristics include a maximum turn-on time of 50 us and a maximum idle time of 10 us. The component supports surface mount installation in a U-DFN2018-6 package and functions reliably across an operating temperature range from -40 C to +85 C.

Feature Summary

• Integrates active high-side switching capability for single-channel power distribution applications
• Includes built-in fault protection mechanisms such as fixed current limiting and overtemperature shutdown
• Provides status indication through a dedicated flag output pin

Applications

• USB port power switching and distribution
• Peripheral device power management
• Battery-powered equipment load control

Procurement Notes

Verify the specific manufacturer part number against official Diodes Incorporated documentation to confirm package type, electrical ratings, and revision status. Ensure compatibility with design requirements regarding thermal performance and interface logic levels before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring a single high-side switch with moderate current capacity. Consider the 110 mOhm on-resistance for efficiency calculations and verify that the 0.5 A output rating aligns with the target load requirements while respecting the 800 mA current limit threshold.
