MIC2536-1BMM-TR

Overview

The MIC2536-1BMM-TR is a dual-channel USB power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 2.7V to 5.5V and provides a fixed current limit of 150mA per channel. The device features an N-channel output configuration with a typical on-resistance of 425 milliohms. Designed for surface-mount applications, it utilizes an 8-pin MSOP package. The component supports active-high enable logic and functions effectively across an operating temperature range from -40°C to 85°C.

Feature Summary

• Dual-channel architecture providing independent control over two USB power lines
• Integrated fixed current limiting to protect downstream loads from overcurrent conditions
• N-channel output design ensuring low on-resistance for efficient power delivery
• Active-high enable logic simplifies interface with standard digital control signals

Applications

• USB hub power distribution circuits
• Portable electronic device power management
• Peripheral connection protection systems
• Battery-powered equipment load switching

Procurement Notes

Verify the specific suffix 'BMM' confirms the 8-pin MSOP package and tape-and-reel packaging format required for your assembly process. Ensure the manufacturer designation aligns with Microchip Technology, as historical Micrel branding may appear in legacy documentation. Confirm RoHS compliance status through official datasheets before finalizing procurement specifications for regulatory adherence.

Selection Notes

Select this component when dual-channel USB power switching is required with a 150mA current limit per port. The 8-pin MSOP package suits space-constrained designs compared to larger SOIC options. Consider the 2.7V minimum input voltage for compatibility with single-cell lithium-ion battery systems. Verify that the active-high enable logic matches your system's control interface requirements.

Part Context

This part belongs to the MIC2536 family of USB power switches, designed specifically for distributing power in USB-enabled devices. It serves as a compact solution for managing multiple peripheral connections while providing essential overcurrent protection. The device integrates seamlessly into portable electronics where space efficiency and reliable power distribution are critical design parameters.

Replacement Considerations

Direct substitutes include other variants within the MIC2536 series such as MIC2536-1YM-TR, which offers similar functionality but may differ in package type or thermal characteristics. Always verify pinout compatibility and electrical specifications before substitution to ensure circuit integrity.
