MIC2026-2BN

Overview

The MIC2026-2BN is a dual-channel high-side MOSFET power distribution switch manufactured by Microchip Technology. It operates within a load voltage range of 2.7V to 5.5V and provides a maximum continuous current of 500mA per channel, with an absolute maximum output current of 1.25A. The device features a typical on-resistance of 140mΩ per channel. It includes integrated circuit protection mechanisms such as short-circuit protection and thermal shutdown. The component utilizes an 8-pin DIP package.

Feature Summary

• Dual-channel high-side switching architecture for general-purpose power distribution
• Integrated thermal shutdown and short-circuit protection for load safety
• Fault status flag with filtering capability to prevent false assertions
• Reverse current flow blocking without body diode conduction

Applications

• USB peripheral power management
• ACPI power distribution in computing systems
• General purpose power switching circuits

Procurement Notes

Verify the specific suffix 'BN' against official Microchip documentation to confirm the package type and temperature grade. Ensure compatibility with existing PCB footprints for the 8-DIP configuration. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the required current ratings align with system design specifications before procurement.

Selection Notes

Select this component when dual-channel high-side switching with inherent protection is required for low-voltage applications. It is suitable for designs needing reverse current blocking and soft-start functionality. Consider the 8-DIP package constraints for assembly methods. Evaluate the 500mA per channel limit against peak load requirements to ensure adequate headroom for thermal management.

Part Context

The MIC2026 series consists of dual-channel power distribution switches optimized for circuit protection. This family is designed for general-purpose power switching where reliability and compact size are priorities. The device integrates control logic and power MOSFETs into a single package, simplifying board layout compared to discrete solutions.

Replacement Considerations

The MIC2526 is identified as pin-compatible with the MIC2026 series. Verify electrical parameter equivalence before substitution.
