MIC2536-2BMM TR

Overview

The MIC2536-2BMM TR is a dual-channel high-side power switch optimized for bus-powered Universal Serial Bus (USB) applications. It features two independently controlled N-channel outputs with a maximum output current of 150mA per channel. The device operates within a load voltage range of 3V to 5.5V and utilizes an 8-pin MSOP package. Key electrical parameters include a typical on-resistance of 400 milliohms and a fixed current limit of 275mA. It supports active-high enable logic and includes integrated fault protection mechanisms such as thermal shutdown and overcurrent limiting.

Feature Summary

• Dual independent channels for separate USB port control
• Integrated thermal shutdown and fixed current limiting for fault protection
• Optimized for low-power bus-powered USB applications

Applications

• Bus-powered USB hubs
• USB peripheral power distribution
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified partners. Confirm the specific suffix 'TR' indicates tape and reel packaging suitable for automated assembly processes. Ensure compliance with relevant environmental standards, noting that RoHS status may vary by production batch. Request official datasheets and lot traceability documentation prior to procurement to validate part integrity and storage conditions.

Selection Notes

Select this component when designing systems requiring independent control of two USB ports with moderate current demands. It is suitable for applications where space constraints favor the compact MSOP package. Engineers should consider the 150mA continuous output capability and 275mA current limit when sizing downstream loads. Verify that the 3V to 5.5V operating range aligns with the system's power supply architecture.

Part Context

This part belongs to the MIC2536 series of USB power distribution switches manufactured by Microchip Technology. It serves as a specialized solution for managing power delivery in USB-centric designs. The series provides cost-effective integration of switching and protection functions, reducing the bill of materials compared to discrete solutions. It complements other variants in the family that offer different pin counts or channel configurations.

Replacement Considerations

Direct substitutes include the MIC2536-2BM-TR and MIC2536-1YM-TR from Microchip Technology. These alternatives share similar functional characteristics but may differ in package type or channel count. Verify pinout compatibility and electrical specifications before substitution to ensure seamless integration into existing designs without hardware modifications.
