MIC2537-2BM-TR

Overview

The MIC2537-2BM-TR is a quad high-side power distribution switch designed for USB applications. It features four independent N-channel outputs with a maximum output current of 150mA per channel and a typical on-resistance of 425mOhm. The device operates within a load voltage range of 3V to 5.5V and utilizes a 16-SOIC package. Key electrical characteristics include a fixed current limit, overtemperature protection, and controlled slew rate functionality.

Feature Summary

• Integrates four independent high-side switches for efficient power distribution
• Provides integrated fault protection including fixed current limiting and thermal shutdown
• Features controlled slew rate to minimize inrush current during startup

Applications

• USB hub power management
• Portable electronic device power distribution
• Peripheral circuit protection

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to discontinued status. Confirm RoHS compliance requirements as the specific part may not meet current environmental standards. Validate package integrity and pin alignment against the 16-SOIC specification before integration into final assembly processes.

Selection Notes

Select this component for designs requiring compact quad-channel power switching with built-in protection. Ensure input logic levels match the non-inverting interface requirement. Verify that the 150mA per-channel current rating meets load demands without exceeding thermal limits under worst-case operating conditions.

Part Context

This part belongs to the MIC2537 series of power distribution switches from Microchip Technology. It serves as a specialized solution for managing multiple low-power loads in space-constrained environments. The series is optimized for USB-related applications where reliable power sequencing and fault isolation are critical for system stability.

Replacement Considerations

MIC2537-2YM-TR is listed as a direct substitute.
