MIC2594-1YM

Hot Swap Controllers Overview

The MIC2594-1YM is a single-channel negative voltage hot-swap controller designed for safe insertion and removal of circuit boards into live high-voltage backplanes. It manages inrush current and output voltage ramping using minimal external components. The device operates within a supply voltage range of 3 V to 5.5 V and supports an input voltage up to -48 V. Key electrical parameters include a maximum operating temperature of +85 °C, a minimum operating temperature of -40 °C, and a typical supply current of 3 mA. It is housed in an 8-SOIC surface-mount package.

Hot Swap Controllers Feature Summary

• Programmable current limit, slew rate, and under-voltage lockout (UVLO) thresholds
• Integrated protection against overcurrent, overtemperature, and reverse polarity conditions
• Designed for safe hot-plugging into powered high-voltage system backplanes

Hot Swap Controllers Applications

• High-voltage system backplane power distribution
• Telecommunications equipment power modules
• Industrial control board insertion systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'YM' corresponds to the 8-SOIC package variant when sourcing. Confirm that the application requires negative voltage management, as this controller is optimized for -48 V systems. Ensure compatibility with the required UVLO and current limit settings before finalizing procurement specifications.

Hot Swap Controllers Selection Notes

Select the MIC2594-1YM for applications requiring precise control over negative voltage hot-swap events. It is suitable where programmable ramp rates and current limits are necessary to prevent bus disturbances. Consider the 8-SOIC package constraints and the -40 °C to +85 °C operating temperature range during thermal design.

Hot Swap Controllers Part Context

This component belongs to the MIC25xx series of hot-swap controllers from Microchip Technology. These devices are engineered to protect sensitive electronics during board insertion and removal. The MIC2594 specifically addresses negative voltage requirements, distinguishing it from positive voltage counterparts in the same family.
