LTC4231HMS-1#PBF

Hot Swap Controllers Overview

The LTC4231HMS-1#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7 V to 36 V and features adjustable current limiting for power distribution protection. The device draws a typical quiescent current of 4 µA and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact 12-lead MSOP format, it supports surface-mount installation for efficient board space utilization.

Hot Swap Controllers Feature Summary

• Provides adjustable current limiting to protect downstream circuits during insertion or fault conditions
• Supports safe hot swapping of live backplanes without system disruption
• Integrates high-side switch control with low quiescent current consumption

Hot Swap Controllers Applications

• Hot swap controllers for backplane systems
• Power distribution units requiring overcurrent protection
• Industrial equipment with modular card insertion requirements

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance documentation matches the specific manufacturing batch. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet to prevent package degradation prior to assembly.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring single-channel hot swap capability with adjustable current limits. Consider the MSOP-12 package constraints for thermal management and PCB layout. Evaluate the 36 V maximum input rating against system bus voltages to ensure adequate headroom for transient events.
