MIC2549A-2BN

Overview

The MIC2549A-2BN is a high-side power switch IC from Microchip Technology, designed for low-loss DC power switching and distribution. It features an N-channel output with a load voltage range of 2.7V to 5.5V. The device includes programmable current limiting and over-temperature protection with latch functionality. It utilizes an On/Off interface for control. The component is available in standard encapsulation and serves as an integrated solution for power management applications requiring precise current regulation and thermal safety.

Feature Summary

• Integrated high-side power switching with N-channel output configuration
• Programmable current limit capability for precise load protection
• Over-temperature latch protection mechanism for enhanced system safety

Applications

• Low-loss DC power switching systems
• Power distribution networks
• General power management applications

Procurement Notes

Verify the manufacturer designation carefully, as historical documentation may reference Micrel Semiconductor due to acquisition history. Confirm the specific suffix 'BN' matches your required packaging and tape-and-reel specifications. Ensure compatibility with the 2.7V to 5.5V operating voltage range for your target circuit design before finalizing procurement.

Selection Notes

Select this component when a high-side switch with programmable current limiting is required for 3.3V or 5V systems. It is suitable for applications needing robust over-temperature protection with a latching feature to prevent damage during fault conditions. Consider the TSSOP-14 package availability if space constraints exist, although the BN suffix indicates a specific standard package variant.

Part Context

This part belongs to the MIC2545A/MIC2549A series of integrated high-side power switches. These devices are optimized for efficient power distribution and management. The series provides solutions for protecting loads against overcurrent and thermal faults while maintaining low on-resistance for minimal power loss during normal operation.
