MIC2042-1YTS-TR

Overview

The MIC2042-1YTS-TR is a single-channel high-side power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 0.8 V to 5.5 V and supports a programmable current limit between 0.5 A and 3 A. The device features a typical on-resistance of 38 mΩ (with a maximum of 40 mΩ) and utilizes a 14-pin TSSOP package. It includes undervoltage lockout with a typical threshold of 0.225 V, active-high enable logic, and thermal shutdown protection. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Integrates a low-voltage high-side switch with programmable current limiting for precise load protection.
• Includes built-in thermal shutdown and undervoltage lockout mechanisms to ensure operational safety under fault conditions.

Applications

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

Procurement Notes
