MIC2547-1YTS

Overview

The MIC2547-1YTS is a dual programmable current limit single high-side switch manufactured by Microchip Technology. It features two independent output channels capable of delivering up to 500 mA each, with a configurable current limit range from 100 mA to 1.5 A. The device operates within a supply voltage range of 2.7 V to 5.5 V and exhibits a maximum on-resistance of 120 mΩ. Key timing parameters include a maximum turn-on time of 5 ms and a maximum off-time of 22 μs. It is designed for low-loss DC power switching applications.

Feature Summary

• Dual independent high-side switch channels with programmable current limiting
• Configurable current threshold range supporting diverse load requirements
• Low on-resistance design optimized for efficient power distribution
• Integrated protection against overcurrent conditions

Applications

• Advanced Configuration and Power Interface (ACPI) power management
• Low-loss DC power switching systems
• General-purpose power distribution networks

Procurement Notes

Verify the specific suffix '1YTS' corresponds to the TSSOP-16 package and tube packing configuration when ordering. Confirm that the required current limit settings align with the device's programmable range. Ensure thermal management strategies account for the operating temperature range of -40°C to +85°C. Cross-reference the latest datasheet revision to confirm pinout compatibility and electrical specifications before finalizing procurement.

Selection Notes

Select this component when dual-channel high-side switching with adjustable current limits is required. The device suits applications needing precise control over load current without external sensing components. Consider the 120 mΩ maximum on-resistance for efficiency calculations. Verify that the 2.7 V to 5.5 V input range matches the system power rail. Evaluate the 5 ms turn-on time for inrush current management requirements.

Part Context

The MIC2547 series integrates dual high-side switches into a single compact package. This family targets power management ICs for portable and industrial electronics. The MIC2547-1YTS variant specifically utilizes a TSSOP-16 footprint. It complements other Microchip power distribution solutions by offering integrated current limiting capabilities.
