LTC4260CSW#PBF

Hot Swap Controllers Overview

The LTC4260CSW#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc., designed for positive high-voltage applications. It operates within an input supply voltage range of 8.5 V to 80 V and draws a typical operating supply current of 2 mA. The device is housed in a 24-SOIC surface-mount package and functions reliably across a temperature range of 0°C to +70°C. Key programmable features include adjustable current limiting, fault timeout, automatic retry, overvoltage protection (OVP), undervoltage lockout (UVLO), and slew rate control. Communication with the system is facilitated via an I2C-compatible interface.

Hot Swap Controllers Feature Summary

• I2C-compatible interface enables digital monitoring and configuration of operational parameters.
• Adjustable current limiting allows precise control of inrush current during board insertion.
• Integrated fault management includes automatic retry, fault timeout, and latch-off capabilities.
• Programmable slew rate controls the voltage ramp-up speed to minimize bus disturbances.

Hot Swap Controllers Applications

• Positive high-voltage hot swap controllers
• General-purpose power management ICs
• Board insertion systems requiring controlled power sequencing

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels between 8.5 V and 80 V. Confirm that the 24-SOIC footprint matches the PCB layout requirements. Validate I2C address settings if multiple controllers are present on the same bus.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring precise control over power-up sequences and fault handling for positive voltage rails. It is suitable for applications needing digital monitoring via I2C without internal switching elements. Consider the 24-SOIC package constraints and thermal dissipation capabilities relative to the expected load currents and ambient temperatures.

Hot Swap Controllers Part Context

This part belongs to the LTC4260 series of hot swap controllers from Analog Devices. It serves as a general-purpose solution for protecting backplanes and boards during insertion. Unlike integrated power switches, it requires an external N-channel MOSFET to handle the main current path, offering flexibility in selecting components based on specific current and voltage ratings.
