Hot Swap Controllers datasheet and documents for LT1641IS8#PBF

LT1641IS8#PBF

Hot Swap Controllers Overview

The LT1641IS8#PBF is a positive high-voltage hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 9V to 80V and is housed in an 8-SOIC package. The device features programmable current limiting with adjustable sense voltages, automatic retry or latch-off modes upon fault, and undervoltage lockout (UVLO). It includes a power good output for monitoring and supports external MOSFET control for safe insertion and removal from live backplanes.

Hot Swap Controllers Feature Summary

Programmable foldback current limiting that dynamically adjusts based on output voltage to reduce power dissipation
Supports both automatic retry and latch-off modes for fault recovery management
Integrated undervoltage lockout and overvoltage protection via the ON pin with hysteresis
High-side gate driver compatible with standard N-channel MOSFETs

Hot Swap Controllers Applications

Electronic circuit breakers
Industrial alarm systems
Power module protection
24V/48V backplane hot swapping

Hot Swap Controllers Procurement Notes

Verify the specific suffix IS8#PBF against the manufacturer's latest datasheet to confirm the SOIC-8 package and lead-free status. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Confirm that the input voltage does not exceed the absolute maximum ratings during transient events. Check for availability constraints as distribution channels may vary.

Hot Swap Controllers Selection Notes

Select this component when designing circuits requiring safe insertion into live backplanes with voltages up to 80V. It is suitable for applications needing precise current limit control and flexible fault response options. Consider the external MOSFET requirements and thermal management needs associated with the chosen sense resistor configuration.

Hot Swap Controllers Part Context

The LT1641 belongs to Analog Devices' family of hot swap controllers designed for high-voltage applications. It addresses the challenges of inserting and removing boards from powered systems without causing damage or system instability. The device integrates essential protection features typically found in discrete solutions into a single compact IC.
