Overview
The MIC2026-1YM is a dual high-side N-channel MOSFET power switch designed for USB power distribution applications. It features an integrated current limit and thermal shutdown to protect both the device and the load. The component operates with a supply voltage range of 2.7V to 5.5V and delivers a maximum output current of 1.25A per channel. It has a typical on-resistance of 90 milliohms and utilizes an 8-SOIC package. Key protection features include fixed current limiting, over-temperature shutdown, and under-voltage lockout (UVLO).
Feature Summary
- Integrates high-side N-channel MOSFETs for efficient power switching in low-voltage systems.
- Provides comprehensive fault protection through built-in current limiting and thermal shutdown mechanisms.
- Includes status flag functionality to indicate operational state or fault conditions.
- Features controlled slew rate to minimize inrush current and electromagnetic interference during turn-on.
Applications
- USB hub power distribution circuits
- Peripheral port protection in consumer electronics
- General-purpose power distribution in embedded systems
Procurement Notes
Verify that the specific suffix 'YM' corresponds to the tube packaging format rather than tape-and-reel variants like 'TR'. Confirm the manufacturer source is Microchip Technology, as historical data may reference Micrel. Ensure the part meets RoHS3 compliance standards required for modern assembly processes. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component when a dual-channel high-side switch with integrated protection is required for 5V USB applications. The 1.25A current rating supports standard USB peripheral loads. Consider the 8-SOIC package constraints for PCB layout. Verify that the input control logic levels are compatible with the system's microcontroller or host controller outputs.
Part Context
The MIC2026 series belongs to Microchip's portfolio of optimized power distribution switches. Originally developed by Micrel before acquisition, these devices are tailored for USB and general-purpose load switching. The MIC2026-1YM specifically denotes the non-inverting input variant packaged in tubes, distinguishing it from other pinout or packaging options within the same functional family.
Replacement Considerations
MIC2026-2YM is a direct functional substitute with inverted input logic. MIC2026-1YM-TR offers identical electrical performance but in tape-and-reel packaging for automated assembly. Other MIC2026 variants may differ in current ratings or package types.
