MIC2588-2BM

Hot Swap Controllers Overview

The MIC2588-2BM is a single-channel, negative high-voltage hot swap power controller manufactured by Microchip Technology. Designed for safe insertion and removal from live -48V nominal backplanes, this integrated circuit operates within an input voltage range of 19V to 80V. It utilizes an 8-SOIC surface-mount package with a width of 3.90mm. The device serves as a pin-for-pin functional equivalent to the LT1640, LT1640A, and LT4250, facilitating direct replacement in existing designs requiring robust power management for negative voltage applications.

Hot Swap Controllers Feature Summary

• Provides safe insertion and removal capabilities for circuits connected to live negative voltage backplanes
• Functions as a pin-compatible alternative to legacy LT1640 and LT4250 controllers
• Engineered specifically for single-channel negative high-voltage hot swap power control applications

Hot Swap Controllers Applications

• Safe insertion and removal of modules from live -48V nominal backplanes
• Negative high-voltage hot swap power controller implementations
• Direct replacement for LT1640/LT1640A/LT4250 based power management designs

Hot Swap Controllers Procurement Notes

Verify the specific suffix '2BM' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with -48V systems. Confirm that the 8-SOIC footprint matches your PCB layout requirements. Check for moisture sensitivity levels if reflow soldering is planned. Validate that no ordering suffix changes affect the internal functionality compared to the base MIC2588 model.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring safe hot swapping on negative voltage rails up to 80V. It is suitable for replacing older LT1640 or LT4250 designs without schematic modifications due to pin compatibility. Consider the 8-SOIC package constraints for board space. This controller addresses the need for controlled power ramp-up during module insertion to prevent inrush currents and system disturbances.

Hot Swap Controllers Part Context

The MIC2588 series belongs to Microchip's portfolio of hot swap controllers, originally developed under Micrel Semiconductor before acquisition. These devices are engineered to manage power delivery during dynamic connection events. The MIC2588-2BM variant specifically targets negative voltage environments, offering protection and controlled startup sequences essential for maintaining system stability in telecommunications and industrial infrastructure.

Hot Swap Controllers Replacement Considerations

The MIC2588-2BM is documented as a pin-for-pin functional equivalent to the LT1640, LT1640A, and LT4250. Verify electrical specifications match your design requirements before substitution. Ensure the negative voltage operation aligns with your system architecture.
