MIC2585-1LBTS

Hot Swap Controllers Overview

The MIC2585-1LBTS is a dual-channel hot-swap controller manufactured by Microchip Technology, designed for safe board insertion into live backplanes. It operates within an input voltage range of 1 V to 13.2 V and features a 100 mV current sense threshold. The device is housed in a 24-pin TSSOP package with exposed pad (EP) for enhanced thermal performance. Key electrical characteristics include adjustable slew rate control for inrush limiting and under-voltage lockout (UVLO). The component supports independent channel operation with programmable fault response options.

Hot Swap Controllers Feature Summary

• Dual-channel architecture enabling independent control of two positive voltage rails
• Integrated high-side P-channel MOSFET driver with low on-resistance
• Programmable soft-start and slew rate control to limit inrush current
• Precision current sensing with latching or auto-retry fault protection

Hot Swap Controllers Applications

• Server blade insertion into live system backplanes
• Telecommunications equipment power distribution modules
• Industrial control boards requiring hot-plug capability
• Networking hardware expansion cards

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'LBTS' against the official datasheet to confirm pinout compatibility and thermal pad configuration. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for end-of-life or not recommended for new design (NRND) status prior to finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot-swap functionality is required for voltages up to 13.2 V. Ensure the application demands a 100 mV sense threshold and benefits from the 24-pin TSSOP EP package for thermal management. Compare against single-channel alternatives if only one rail requires protection.

Hot Swap Controllers Part Context

The MIC2585 belongs to Microchip's family of hot-swap controllers, which provide overcurrent and overvoltage protection during board insertion. This series is engineered for systems where continuous operation must be maintained while adding or removing modules. The device integrates gate drive circuitry to manage external or internal power switches safely.
