LT1641-2IS8#PBF

Hot Swap Controllers Overview

The LT1641-2IS8#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 features programmable current limiting, fault timeout, overvoltage protection (OVP), slew rate control, and undervoltage lockout (UVLO). The device supports automatic retry functionality and is housed in an 8-SOIC package with a wide operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates programmable current limiting with foldback characteristics to manage power dissipation during fault conditions.
• Provides comprehensive protection mechanisms including overvoltage detection, undervoltage lockout, and configurable fault timeouts.
• Supports automatic retry modes for transient fault recovery without requiring manual intervention.

Hot Swap Controllers Applications

• Electronic circuit breakers
• Industrial alarm systems
• Power module protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix IS8 against the datasheet to confirm the SOIC-8 package variant. Confirm RoHS compliance status as indicated in official documentation. Check for availability constraints or limited supply notices from authorized distributors before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component for applications requiring precise control over inrush current and short-circuit protection in high-voltage environments. Ensure the external sense resistor values align with the programmable threshold requirements. Verify that the system voltage does not exceed the maximum rated input limits.
