MIC2076-1BN

Overview

The MIC2076-1BN is a high-side N-channel MOSFET power switch manufactured by Microchip Technology. It features two independent outputs with a 1:2 input-to-output ratio, supporting a maximum continuous output current of 1.25A per channel. The device operates within a load voltage range of 2.7V to 5.5V and utilizes an 8-pin PDIP package. Key electrical characteristics include a typical on-resistance of 90 milliohms and fixed current limiting protection. It incorporates thermal shutdown and under-voltage lockout (UVLO) for comprehensive circuit protection.

Feature Summary

• Integrated smart shutdown capability that reduces current consumption during fault modes
• Soft-start circuitry designed to minimize inrush current for highly capacitive loads
• Fault status flag output asserted during overcurrent or thermal shutdown conditions
• Internally filtered transient faults to prevent false triggering

Applications

• General-purpose power distribution requiring circuit protection
• USB application power switching
• High-side load switching in embedded systems

Procurement Notes

Verify the specific package variant when ordering, as the MIC2076 series is available in both SOIC and PDIP configurations. Confirm the manufacturer source, noting historical transitions from Micrel to Microchip Technology. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the full part number suffix to guarantee the correct pinout and packaging type matches your PCB design requirements.

Selection Notes

Select this component for applications requiring dual high-side switching with integrated protection in a through-hole package. The MIC2076-1BN is suitable where soft-start functionality is critical to manage capacitive loads. Consider the 1.25A current limit and 90mΩ on-resistance for power dissipation calculations. Ensure the operating temperature range of -40°C to 85°C aligns with your environmental specifications.

Part Context

The MIC2076-1BN belongs to the MIC2076 family of dual-channel power distribution switches. This series is optimized for general-purpose power distribution tasks requiring robust circuit protection. The device integrates high-side N-channel MOSFETs with control logic to provide efficient switching and fault management in compact packages.

Replacement Considerations

The MIC2076-1YM is a direct functional substitute offering identical electrical specifications but housed in an 8-SOIC surface-mount package instead of the 8-PDIP through-hole configuration. Verify footprint compatibility before substitution.
