LTC4210-4IS6#TRPBF

Hot Swap Controllers Overview

The LTC4210-4IS6#TRPBF is a Hot Swap controller from Analog Devices Inc., designed for safe board insertion and removal from live backplanes. It operates with supply voltages ranging from 2.7V to 16.5V and features an internal high-side switch driver for external N-channel MOSFETs. The device provides adjustable analog current limiting with a circuit breaker timer and fast response peak fault current limiting. It supports latch-off behavior on overcurrent faults, adjustable power-up rates, and undervoltage lockout. Packaged in a low-profile 6-lead SOT-23 (ThinSOT) package, it is suitable for industrial applications requiring electronic circuit breaker functionality.

Hot Swap Controllers Feature Summary

• Enables safe hot insertion and removal of boards from live backplanes
• Provides adjustable analog current limiting with integrated circuit breaker timer
• Features fast response loop to limit peak fault currents
• Configurable for latch-off operation on overcurrent faults

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the -4 variant corresponds to the intended latch-off fault handling mode required by the design. Ensure the operating voltage range aligns with the system's 2.7V to 16.5V specification. Check for RoHS compliance documentation as part of the standard procurement checklist.

Hot Swap Controllers Selection Notes

Select this component when a compact solution for single-channel hot swap protection is needed. The SOT-23-6 package offers a small footprint for space-constrained designs. Choose the -4 suffix if latch-off behavior is preferred over automatic retry for fault conditions. Ensure the external MOSFET gate drive requirements are compatible with the internal driver capabilities.

Hot Swap Controllers Part Context

This part belongs to the LTC4210 family of Hot Swap controllers, which includes variants with different fault handling options such as automatic retry or latch-off. The family is designed to protect circuits during insertion into live backplanes. The IS6 designation indicates industrial temperature range performance within the ThinSOT package.

Hot Swap Controllers Replacement Considerations

The LTC4210-2IS6#TRPBF is a confirmed substitute offering identical electrical characteristics but with automatic retry on overcurrent faults instead of latch-off. Verify that the application logic can tolerate the retry behavior before swapping.
