LTC4231IMS-2#PBF

Hot Swap Controllers Overview

The LTC4231IMS-2#PBF is a micro-power hot-swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of circuit boards from live backplanes. It operates within a supply voltage range of 2.7 V to 36 V and features adjustable current limiting. The device supports single-channel control with a quiescent current of 4 uA, ensuring minimal power consumption during standby. It is housed in a 12-pin MSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Micro-power operation with low quiescent current for energy-efficient applications
• Adjustable current limiting to protect against overcurrent conditions
• Integrated auto-retry functionality for fault recovery

Hot Swap Controllers Applications

• Safe insertion and removal of circuit boards from live backplanes
• Power distribution systems requiring controlled power-up sequencing
• Hot-swap applications in telecommunications and industrial equipment

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the IMS-2 variant corresponds to the auto-retry feature set required for your design. Ensure the MSOP-12 package footprint matches your PCB layout constraints. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when low standby power is critical alongside hot-swap capabilities. The adjustable current limit allows customization for various load requirements. Consider the 36V maximum input rating to ensure compatibility with system bus voltages. The MSOP-12 package offers a compact solution for space-constrained designs compared to larger packages.

Hot Swap Controllers Part Context

This part belongs to the LTC4231 series of micro-power hot-swap controllers. It is functionally related to the LTC4231IMS-1#PBF, which features latch-off instead of auto-retry. The DC2161A-B evaluation board is specifically designed to demonstrate the performance of the LTC4231IMS-2 variant in practical applications.

Hot Swap Controllers Replacement Considerations

LTC4231IMS-1#PBF serves as a direct alternative if latch-off behavior is preferred over auto-retry. For higher current applications, consider the LTC4232IDHC-1#PBF. Verify package compatibility and functional differences before substituting.
