LTC4210-4IS6#TRMPBF

Hot Swap Controllers Overview

The LTC4210-4IS6#TRMPBF is a Hot Swap controller manufactured by 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 adjustable analog current limit with a circuit breaker timer. The device provides fast response peak fault current limiting and includes an automatic retry function on overcurrent faults. It utilizes a high-side driver for an external N-channel MOSFET and offers adjustable supply voltage power-up rates. The component is housed in a low-profile 6-lead SOT-23 package and supports industrial temperature ranges.

Hot Swap Controllers Feature Summary

• Enables safe hot insertion and removal of boards from live backplanes
• Provides active current limiting with a circuit breaker timer for fault protection
• Features automatic retry capability upon recovery from overcurrent faults
• Controls external N-channel MOSFETs via a high-side gate driver

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRMPBF indicates tape-and-reel packaging when sourcing. Confirm the IS6 designation corresponds to the industrial temperature range requirements for your environment. Ensure compatibility with the 2.7V to 16.5V input voltage window. Check for availability constraints as distribution status may vary. Validate that the external MOSFET selection aligns with the controller's drive capabilities.

Hot Swap Controllers Selection Notes

Select this model when automatic retry after fault conditions is required, distinguishing it from latch-off variants. Ensure the application voltage does not exceed the 16.5V maximum rating. Verify that the SOT-23-6 package footprint fits the PCB layout constraints. Consider the external MOSFET requirements since the internal switch is absent. Confirm the industrial temperature grade meets operational environmental standards.

Hot Swap Controllers Part Context

This component belongs to the LTC4210 family of Hot Swap controllers from Analog Devices. The family includes variants with different fault handling behaviors, such as latch-off options. The part integrates timing control and protection logic for single-channel power distribution. It is categorized under Power Management ICs (PMIC) specifically for power distribution and switching applications.

Hot Swap Controllers Replacement Considerations

The LTC4210-2 series serves as a functional alternative if a latch-off response to overcurrent faults is preferred instead of automatic retry. Both share similar voltage ranges and package types but differ in fault recovery behavior.
