MIC2585-1MBTS-TR

Hot Swap Controllers Overview

The MIC2585-1MBTS-TR is a dual-channel hot-swap voltage controller manufactured by Microchip Technology, formerly Micrel. It supports input supply voltages from 1V to 13.2V and operates within a temperature range of -40°C to 85°C. The device draws a typical supply current of 1.7 mA and is housed in a 24-pin TSSOP package with a 4.40mm width. Key programmable features include fault timeout, overvoltage protection (OVP), slew rate control, and under-voltage lockout (UVLO). This component is designed for safe insertion and removal of circuit boards while powered.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent or sequenced power management
• Programmable soft-start and fault protection parameters
• Integrated high-side P-channel MOSFET driver capability

Hot Swap Controllers Applications

• PCI/PCI-X backplane systems
• CompactPCI and PCI Express card edge connectors
• General-purpose hot-swap power distribution

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'MBTS' confirms the 24-TSSOP package and tape-and-reel quantity of 2500 units. Confirm RoHS compliance status as listed in the official datasheet. Check for any recent Product Change Notices (PCN) regarding assembly sites or material changes. Ensure the source document explicitly identifies this part as discontinued or last-time-buy if applicable, as availability may be limited.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot-swap control is required for bus architectures supporting up to 13.2V. Compare against single-channel variants like the MIC2585-0 if only one rail needs protection. Consider the MIC2585-2 series if identical channel matching or specific sequencing requirements differ from the '-1' variant. Verify that the TSSOP-24 footprint matches the PCB design constraints.

Hot Swap Controllers Part Context

This part belongs to the MIC2585 family of hot-swap controllers, originally developed by Micrel before its acquisition by Microchip Technology. The family includes variants with different channel counts and pinouts. The '-1' designation typically indicates specific internal timing or threshold characteristics distinct from other family members. These controllers are standard solutions for managing power delivery during board insertion events.

Hot Swap Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with the MIC2585-1KBTS or MIC2585-1JYTS only if pin compatibility and electrical specifications are verified against the original datasheet.
