MIC2585-2JBTS-TR

Hot Swap Controllers Overview

The MIC2585-2JBTS-TR is a dual-channel hot-swap voltage controller manufactured by Microchip Technology. It is designed for safe insertion and removal of circuit boards into live backplanes without disrupting system power. The device operates within an input voltage range of 1V to 13.2V and supports a supply voltage range of 2.3V to 13.2V. It features adjustable current limit thresholds, programmable slew rates, and under-voltage lockout (UVLO) protection. The component is housed in a 24-pin TSSOP package and is rated for operation from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent control of two load paths
• Integrated fault protection with latch-off capability
• Programmable soft-start and current limiting functions
• Under-voltage lockout ensures stable operation during power transitions

Hot Swap Controllers Applications

• Server blade insertion into live backplanes
• Telecommunications equipment hot-plug modules
• Industrial control board expansion slots
• Networking hardware modular interface cards

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'JBTS' against official Microchip documentation to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list obsolete or NRND parts. Ensure the 24-pin TSSOP footprint matches the target PCB design. Cross-reference datasheet revisions for any recent parameter updates before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when dual-channel isolation is required for hot-swap applications. Compare against single-channel alternatives like the MIC2582 if only one path is needed. Verify that the 13.2V maximum rating aligns with the system bus voltage. Consider the TSSOP-24 package constraints relative to available board space and thermal requirements.

Hot Swap Controllers Part Context

This part belongs to the MIC2585 family of hot-swap controllers, which are successors to earlier Micrel designs acquired by Microchip. The family provides robust protection for high-density electronic systems requiring frequent maintenance or upgrades. The dual-channel variant specifically addresses applications needing simultaneous management of multiple power rails or redundant loads.

Hot Swap Controllers Replacement Considerations

MIC2585-2KYTS is a documented alternative within the same series offering similar dual-channel functionality.
