LT1641IS8#TRPBF

Hot Swap Controllers Overview

The LT1641IS8#TRPBF 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 a single channel for power management applications. The device is housed in an 8-SOIC surface-mount package with a width of 3.90mm. It supports programmable current limiting, fault timeout, overvoltage protection, slew rate control, and undervoltage lockout. The component functions effectively across an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates programmable foldback current limiting that dynamically adjusts sense resistor voltage drop to reduce power dissipation and prevent overheating during fault conditions.
• Provides high-side gate drive capability ensuring at least 10V drive voltage when input exceeds 20V, maintaining compatibility with standard N-channel MOSFETs.
• Includes undervoltage and overvoltage detection mechanisms via the ON pin with hysteresis to prevent false triggering and ensure stable operation.

Hot Swap Controllers Applications

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

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging rather than tube configuration. Confirm the IS8 designation corresponds to the industrial temperature grade (-40°C to +85°C) and SOIC-8 package dimensions. Ensure the source document explicitly lists this exact part number as available or discontinued status 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. The internal timer allows customization of maximum current limit duration, supporting either latch-off or auto-retry modes based on system recovery requirements. Evaluate external component values for setting the desired trip points and slew rates.

Hot Swap Controllers Part Context

This part belongs to the LT1641 family of positive high-voltage hot swap controllers from Analog Devices. It shares core functionalities with variants like the LT1641CS8 and LT1641-2IS8 but differs in temperature rating and packaging format. The series is designed for robust power distribution management in demanding industrial settings.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Verify compatibility with alternative hot swap controllers such as the LT1641-1 or MIC2587 only if datasheet parameters align precisely with design requirements.
