MIC2045-1YTS

Overview

The MIC2045-1YTS is a high-side power distribution switch from Microchip Technology, designed for general-purpose applications requiring circuit protection. It features an N-channel MOSFET with a maximum on-resistance of 30 mΩ and supports output currents up to 500 mA, with current limiting adjustable between 1 A and 6 A. The device operates within a voltage range of 800 mV to 5.5 V and functions reliably across temperatures from -40°C to +85°C. Packaged in a 16-TSSOP surface-mount format, it includes fault protection mechanisms such as overcurrent limiting.

Feature Summary

• High-side MOSFET switch architecture optimized for robust power distribution
• Integrated overcurrent protection with adjustable current limit thresholds
• Low on-resistance design to minimize power loss during operation
• Wide operating voltage range suitable for low-voltage systems

Applications

• General-purpose power distribution circuits
• Circuit protection in electronic systems
• Load driver applications requiring high-side switching

Procurement Notes

Verify the specific package variant and tape-and-reel configuration when ordering, as the base part number may correspond to different shipping formats. Confirm that the selected component meets the required thermal and electrical specifications for the intended application environment. Cross-reference the manufacturer's latest datasheet to ensure compliance with RoHS standards and other regulatory requirements relevant to the deployment region.

Selection Notes

Select this component for applications requiring a single-channel high-side switch with integrated current limiting. Consider the 16-TSSOP package for surface-mount assembly constraints. Evaluate the adjustable current limit range against the load requirements to ensure adequate protection without nuisance tripping. Ensure the supply voltage falls within the specified 800 mV to 5.5 V operational window.

Part Context

The MIC2045 series comprises high-side MOSFET switches designed for power distribution. The MIC2045-1YTS specifically denotes a single-channel variant within this family. It is engineered to provide reliable switching and protection in low-voltage environments, distinguishing itself through its adjustable current limit capabilities and compact packaging options suitable for dense PCB layouts.

Replacement Considerations

The MIC2043-1YTS is a related single-channel high-side switch from the same manufacturer. While it shares similar voltage ranges and packaging, it features a higher on-resistance and fixed current limit. Verify compatibility regarding current handling and thermal performance before substitution.
