MIC2594-2BM-TR

Hot Swap Controllers Overview

The MIC2594-2BM-TR is a single-channel hot swap controller manufactured by Microchip Technology. It supports -48V systems and features programmable current limit, slew rate control, and under-voltage lockout (UVLO). The device is housed in an 8-SOIC surface-mount package. Supply current is specified at 3 mA. It is designed for controlled insertion and removal of circuit boards in live backplane environments.

Hot Swap Controllers Feature Summary

• Programmable current limiting to protect against overcurrent conditions during board insertion
• Controlled slew rate management to minimize inrush current and bus voltage droop
• Integrated under-voltage lockout for reliable operation within specified voltage ranges

Hot Swap Controllers Applications

• -48V telecommunications equipment
• Industrial control systems
• Server and storage backplanes

Hot Swap Controllers Procurement Notes

Verify component status as the part may be discontinued or limited in availability through major distributors. Confirm package integrity and authenticity upon receipt. Ensure compatibility with existing -48V system architectures before integration. Check for updated replacement recommendations from the manufacturer due to potential end-of-life status.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise control of power-up sequences in -48V environments. Consider its programmable features for tailoring protection thresholds. Evaluate the 8-SOIC package constraints for PCB layout. Verify that the supply current and operating temperature range meet system requirements.

Hot Swap Controllers Part Context

This component belongs to the MIC2594 series of hot swap controllers from Microchip Technology. It is derived from Micrel designs acquired by Microchip. The series focuses on protecting sensitive electronics during hot insertion events in high-reliability industrial and telecom applications.

Hot Swap Controllers Replacement Considerations
