MIC2537-2BM

Overview

The MIC2537-2BM is a quad power distribution switch designed for high-side load driving applications. It features four 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 a 16-SOIC package. Key electrical characteristics include a typical on-resistance of 425mΩ and fixed current limiting protection. It supports non-inverted input interfaces and includes thermal shutdown capabilities, functioning effectively in temperatures from -40°C to 85°C.

Feature Summary

• Provides four independently controllable high-side power channels optimized for bus-powered USB applications
• Integrates fixed current limiting and thermal shutdown fault protection mechanisms
• Features controlled slew rate functionality to minimize inrush currents during switching events

Applications

• Bus-powered Universal Serial Bus (USB) peripheral devices
• High-side power distribution for multiple low-current loads
• Portable electronic equipment requiring independent channel control

Procurement Notes

Verify component authenticity as the MIC2537-2BM is listed as obsolete by the manufacturer. Confirm RoHS compliance status, as this specific suffix may contain lead and not meet current environmental regulations. Ensure replacement parts are validated for pin compatibility and electrical performance before integration into new designs.

Selection Notes

Select this component when designing systems requiring four isolated high-side switches with moderate current capacity. It is suitable for applications needing integrated overcurrent and thermal protection without external sensing resistors. Consider the 16-SOIC package constraints and verify that the 150mA per channel limit meets the total load requirements of the target application.

Part Context

This part belongs to the MIC2537 series of power distribution switches manufactured by Microchip Technology. The series is engineered for cost-effective management of multiple power rails in compact form factors. The MIC2537-2BM specifically denotes the SOIC package variant with standard operating temperature ranges, distinct from other package options like TQFN available in the broader family.

Replacement Considerations

The MIC2537-2YM is identified as a direct substitute. Verify that the YM suffix variant meets all mechanical and electrical specifications required for the existing footprint and circuit design.
