Overview
The MIC2026A-1YM is a dual-channel high-side N-channel MOSFET power distribution switch designed for general-purpose circuit protection. It operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 1.25A per channel. The device features a typical on-resistance of 90mΩ and utilizes an 8-pin SOIC package with a 3.90mm width. It includes fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO) for robust fault protection.
Feature Summary
- Integrated fixed current limiting and thermal shutdown protect both the device and connected loads from overcurrent and overheating conditions.
- Soft-start circuitry minimizes inrush current when powering highly capacitive loads, ensuring stable system startup.
- Fault status output flag asserts during overcurrent or thermal shutdown events, providing clear diagnostic indication of system faults.
Applications
- USB port power distribution and protection
- General-purpose power bus switching
- Peripheral device power control
Procurement Notes
Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm pinout and electrical parameter alignment with your design requirements. Ensure the 8-SOIC package dimensions match your PCB footprint constraints. Confirm RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component for applications requiring dual-channel high-side switching with integrated protection. It is suitable for low-voltage systems operating between 2.7V and 5.5V. Consider the 1.25A current rating and 90mΩ on-resistance for power dissipation calculations. The non-inverting input interface simplifies control logic integration.
Part Context
This part belongs to the MIC2026/MIC2076 family of high-side MOSFET switches originally developed by Micrel and now manufactured by Microchip Technology. The MIC2026 series focuses on standard protection features, while the MIC2076 variant adds smart shutdown capabilities. Both share similar packaging and core protection mechanisms.
Replacement Considerations
MIC2026-1YM is the direct predecessor without the 'A' designation. MIC2026-2YM offers the same functionality but in a tube package instead of tape and reel. Verify pin compatibility before substitution.
