MIC2026-1YM-TR

Overview

The MIC2026-1YM-TR is a dual-channel high-side N-channel MOSFET power switch optimized for general-purpose power distribution and USB applications. It features a 1:2 input-to-output ratio, supporting up to 1.25A output current with a typical on-resistance of 90 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and includes fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO). Packaged in an 8-SOIC surface-mount format, it functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrated circuit protection via internal fixed current limiting and thermal shutdown mechanisms.
• Soft-start circuitry designed to minimize inrush current when driving highly capacitive loads.
• Fault status flag output asserted during overcurrent or thermal shutdown conditions.
• Transient fault filtering capability to prevent false triggering of protection circuits.

Applications

• USB port power switching and distribution
• General-purpose circuit protection in electronic systems
• Hot-insertion applications requiring controlled turn-on

Procurement Notes

Verify the specific suffix 'TR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the non-inverting input logic aligns with the system control interface. Ensure the 8-SOIC footprint matches the PCB layout specifications. Validate RoHS3 compliance requirements against project standards before finalizing procurement orders.

Selection Notes

Select this component for designs requiring dual-channel high-side switching with integrated fault protection. The 1.25A current rating suits moderate-load applications. Consider the MIC2026A variant if updated silver bonding wire specifications are preferred. Evaluate the MIC2076 series if smart shutdown latching behavior is necessary for fault recovery management.

Part Context

This part belongs to the MIC2026 family of dual-channel power distribution switches manufactured by Microchip Technology. It serves as a direct successor to Micrel-derived designs, maintaining compatibility with established application notes. The device integrates high-side N-channel MOSFETs into a single compact package, replacing discrete solutions for improved reliability and reduced board space.

FAQ

How does the device handle transient faults?

The MIC2026-1YM-TR employs internal transient fault filtering to ignore brief current spikes, preventing unnecessary activation of the current limit or thermal shutdown protections.

What is the function of the soft-start feature?

The integrated soft-start circuitry controls the turn-on speed to minimize inrush current, which is critical when connecting loads with high capacitance to avoid voltage droop.
