MIC2043-1YTS-TR

Overview

The MIC2043-1YTS-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a single output channel with a maximum continuous output current of 500 mA and a programmable current limit set to 3 A. The device exhibits a maximum on-resistance of 60 mΩ and operates within a supply voltage range of 800 mV to 5.5 V. It includes thermal shutdown protection and has a maximum turn-on time of 1 ms and a maximum idle time of 5 µs. The component is designed for surface mount installation in TSSOP-14 packages and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates high-side switching capability with programmable current limiting for precise load protection.
• Includes thermal shutdown circuitry to safeguard the device against overheating conditions.
• Supports low-voltage operation starting from 800 mV, enabling compatibility with various power sources.

Applications

• Power distribution systems requiring single-channel load management
• Peripheral device protection in embedded electronics
• Battery-powered equipment needing efficient power switching

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing components. Confirm that the YTS designation corresponds to the TSSOP-14 package variant. Ensure the procurement documentation explicitly states the 3 A current limit setting, as this parameter defines the protective threshold for the connected load. Cross-reference the manufacturer part number with official Microchip databases to validate authenticity and revision status before integration into production designs.

Selection Notes

Select this component when a single high-side switch with fixed 3 A current limiting is required. The low on-resistance minimizes power loss during conduction. Consider the TSSOP-14 package for space-constrained PCB layouts. Verify that the input voltage range aligns with the system's power supply rails. This device is suitable for applications prioritizing thermal protection and compact form factors over multi-channel configurations.

Part Context

This part belongs to the MIC2043 series of power distribution switches from Microchip Technology. The series offers various channel counts and package options to suit different power management needs. The MIC2043-1YTS-TR specifically provides a single-channel solution with integrated protection features. It is designed to replace discrete MOSFET solutions, simplifying circuit design while enhancing reliability through built-in fault protection mechanisms.

Replacement Considerations

Direct replacements include other MIC2043 variants with compatible pinouts and electrical characteristics. Verify that substitute parts maintain the same 3 A current limit and 60 mΩ on-resistance specifications. Ensure the replacement package matches the TSSOP-14 footprint if board space is constrained. Check for any differences in thermal performance or operating temperature ranges that might affect system reliability.
