LTC4210-2CS6#TRMPBF

Hot Swap Controllers Overview

The LTC4210-2CS6#TRMPBF is a Hot Swap controller housed in a 6-lead SOT-23 package. It manages supply voltages from 2.7V to 16.5V via an external N-channel MOSFET. The device features adjustable analog current limiting with a circuit breaker timer and supports latch-off behavior on overcurrent faults. Operating parameters include a quiescent current of 650 µA, an input voltage range of 2.7V to 12V for the demonstration context, and operation within a commercial temperature range.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of boards from live backplanes
• Provides active current limiting with adjustable circuit breaker timing
• Configurable for automatic retry or latch-off upon overcurrent faults

Hot Swap Controllers Applications

• Hot board insertion systems
• Electronic circuit breakers
• Industrial high-side switch applications

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm that the specific suffix matches the required latch-off functionality. Ensure compatibility with the target voltage range and thermal requirements before finalizing procurement decisions.

Hot Swap Controllers Selection Notes

Select this variant specifically when a latch-off response is required during overcurrent events, distinguishing it from the automatic retry option. Evaluate the need for the compact SOT-23 footprint against available board space constraints. Consider the external MOSFET selection to ensure adequate current handling capabilities.

Hot Swap Controllers Part Context

This component belongs to the LTC4210 series of Hot Swap controllers designed for protecting circuits during hot insertion. It serves as a critical interface between power sources and sensitive loads, ensuring controlled power-up sequences and fault protection in industrial environments.

Hot Swap Controllers Replacement Considerations

The LTC4210-1CS6#TRMPBF offers identical hardware but provides automatic retry instead of latch-off. Verify if the system logic can tolerate transient faults without manual intervention before substituting.
