MIC2026-2BM-TR

Overview

The MIC2026-2BM-TR is a dual-channel high-side power distribution switch manufactured by Microchip Technology. It operates within a voltage range of 2.7V to 5.5V and provides a maximum on-resistance of 140mΩ per channel. The device supports a minimum continuous current of 500mA with an internal current limit of 900mA. It features soft-start circuitry, thermal shutdown, and undervoltage lockout. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates internally current-limited high-side MOSFET switches for general-purpose power distribution requiring circuit protection.
• Includes soft-start circuitry to minimize inrush current when driving highly capacitive loads.
• Provides fault status flag output with transient filtering to eliminate false assertions during overcurrent or thermal shutdown conditions.

Applications

• USB peripheral power switching
• General purpose power distribution
• ACPI power distribution systems

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm the 'B' grade designation aligns with the specified electrical parameters such as the 140mΩ on-resistance. Ensure compatibility with the 8-pin SOIC footprint and check for moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component for applications requiring dual independent high-side switching with integrated protection. It is suitable where logic-compatible inputs and low quiescent current are necessary. Consider the MIC2076 variant if smart shutdown capabilities are required instead of the standard latch-off behavior found in the MIC2026 series.

Part Context

This part belongs to the MIC2026 family of dual-channel power distribution switches originally developed by Micrel, now under Microchip Technology. These devices are designed to replace traditional discrete solutions, offering compact integration of MOSFETs, current limiting, and thermal protection in a single surface-mount package.

Replacement Considerations

The MIC2026-2YM is a pin-compatible alternative within the same family. Verify that the on-resistance and current specifications of the substitute meet the design requirements before implementation.

FAQ

Does the MIC2026-2BM-TR block reverse current flow?

Yes, the device blocks reverse current flow and does not utilize a body diode, preventing back-feeding into the input source.

How is the fault condition cleared after thermal shutdown?

For the MIC2026 series, the output remains latched off until the enable input is toggled or the VIN supply is cycled to reset the device.
