MIC2536-1BMM

Overview

The MIC2536-1BMM is a dual-channel high-side USB power distribution switch manufactured by Microchip Technology. It operates within a voltage range of 2.7V to 5.5V and provides independent control for each channel. The device features a typical on-resistance of 400mΩ and supports a minimum continuous load current of 150mA per channel. It includes slew rate controlled turn-on to minimize inrush current and incorporates fault protection mechanisms such as thermal shutdown and short-circuit protection. The component is housed in an 8-pin MSOP package.

Feature Summary

• Dual independently controlled channels optimized for bus-powered USB applications
• Slew rate controlled turn-on to limit inrush current during connection
• Integrated fault protection including thermal shutdown and short-circuit detection
• Status flag output indicating active or fault conditions

Applications

• Bus-powered Universal Serial Bus (USB) hubs
• USB peripheral power management
• Portable electronic devices requiring USB connectivity
• Industrial USB interface circuits

Procurement Notes

Verify the specific suffix 'BMM' corresponds to the 8-pin MSOP package and tape-and-reel or tube availability as required. Confirm compliance with RoHS directives and check for any lead-free manufacturing updates. Ensure the ordering part number matches the exact temperature grade and packaging format specified in the official Microchip datasheet to avoid functional mismatches.

Selection Notes

Select this component when dual-channel USB power switching with independent control is required. It is suitable for applications needing low on-resistance and built-in inrush current limiting. Consider the 150mA continuous current rating per channel against the load requirements. The MSOP package is ideal for space-constrained designs. Verify input voltage compatibility with the system's 2.7V to 5.5V range.

Part Context

The MIC2536 series consists of dual high-side power switches designed specifically for USB power distribution. These devices integrate current limiting, thermal protection, and status reporting into a compact footprint. They are commonly used in host controllers and hubs to manage power delivery to connected peripherals safely and efficiently.

Replacement Considerations

Direct substitutes include other dual-channel USB power switches from Microchip or compatible manufacturers offering similar 400mΩ on-resistance and 150mA current ratings. Ensure pinout compatibility and identical fault protection features when cross-referencing alternative part numbers.
