MIC2547-1BTS-TR

Overview

The MIC2547-1BTS-TR is a dual high-side power switch from Microchip Technology, designed for USB and general load distribution. It features two independent N-channel outputs with programmable current limits ranging from 100 mA to 1.5 A. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports up to 1.5 A output current per channel. Key electrical parameters include a maximum on-resistance of 120 mΩ, a maximum turn-on time of 5 ms, and a maximum dwell time of 22 μs. It integrates comprehensive protection against overcurrent, overtemperature, and reverse current conditions.

Feature Summary

• Dual high-side switching capability with independent control
• Programmable current limit for flexible load management
• Integrated fault protection including overcurrent, thermal, and reverse current safeguards
• Status flag output for real-time monitoring

Applications

• USB hub power distribution
• Peripheral port protection
• Load switching in consumer electronics

Procurement Notes

Verify the specific suffix 'BTS' indicates the tape-and-reel packaging configuration as required by your assembly process. Confirm that the component meets RoHS compliance standards if mandated by your project specifications. Ensure the operating temperature range aligns with your environmental requirements before finalizing procurement.

Selection Notes

Select this component when dual-channel high-side switching with adjustable current limiting is required. It is suitable for applications needing integrated protection against short circuits and thermal overload. Consider the 16-TSSOP package for surface-mount assembly constraints and verify compatibility with the 2.7 V to 5.5 V system voltage.

Part Context

This part belongs to the MIC2547 family of power switches, which are designed for robust load distribution in low-voltage systems. The MIC2547 series provides a compact solution for managing multiple loads with individual current control, commonly utilized in portable devices and peripheral interfaces requiring reliable power management.

Replacement Considerations

MIC2547-1YM is a direct substitute offering identical functionality in an SOIC package.
