MIC2076-2BM

Overview

The MIC2076-2BM is a dual-channel high-side power distribution switch optimized for general-purpose circuit protection. It features an internal current limit of 900 mA and a maximum on-resistance of 140 mΩ. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports output currents up to 500 mA per channel. It includes soft-start circuitry to minimize inrush current, thermal shutdown with latch-off capability, and a fault status flag. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Smart shutdown functionality reduces current consumption during fault modes
• Internal current limiting and thermal shutdown protect the device and load
• Soft-start circuitry minimizes inrush current for highly capacitive loads
• Fault status output flag indicates overcurrent or thermal conditions

Applications

• USB port power distribution
• General-purpose power distribution requiring circuit protection
• High-side switching for peripheral devices

Procurement Notes

Verify the specific suffix 'BM' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering information matches the exact package type and temperature grade required for your design. Cross-reference the part number with Microchip Technology documentation to avoid confusion with similar variants in the MIC2026A/MIC2076A family.

Selection Notes

Select this component when smart shutdown behavior is required to reduce power consumption during faults, distinguishing it from the MIC2026A series. Consider the 900 mA current limit and 140 mΩ on-resistance for load requirements. Evaluate the need for the fault status flag and latch-off reset mechanism in your system architecture before finalizing the choice.

Part Context

The MIC2076-2BM belongs to the MIC2026A/MIC2076A family of dual-channel power distribution switches manufactured by Microchip Technology (formerly Micrel). These devices are designed as high-side MOSFET switches providing integrated protection features. The MIC2076 variant specifically adds intelligent shutdown capabilities compared to standard counterparts.
