LTC4260IUH#PBF

Hot Swap Controllers Overview

The LTC4260IUH#PBF is a positive high-voltage hot swap controller designed for managing power insertion into live backplanes. It supports an input voltage range of 8.5V to 80V and operates within a temperature range of -40°C to 85°C. The device features an integrated 8-bit ADC for monitoring current and voltage, providing I2C-compatible data access. It utilizes a 32-pin QFN package with an exposed pad for thermal management.

Hot Swap Controllers Feature Summary

• Integrates an 8-bit analog-to-digital converter for real-time monitoring of supply voltage and load current.
• Provides I2C-compatible digital interface for accessing monitored parameters and configuring control settings.
• Features high-side drive capability specifically designed for controlling external N-channel MOSFETs during power insertion.

Hot Swap Controllers Applications

• Hot swap controllers for network infrastructure equipment
• Power management in server blade systems
• Industrial control system power distribution

Hot Swap Controllers Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free and RoHS compliance when sourcing. Confirm the package type matches the 32-WFQFN Exposed Pad specification. Ensure the operating temperature grade corresponds to the 'I' designation for industrial range applications. Cross-reference the manufacturer part number directly with Analog Devices documentation to avoid counterfeit components.

Hot Swap Controllers Selection Notes

Select this component for applications requiring precise monitoring of high-voltage DC inputs up to 80V. The integrated ADC eliminates the need for external sensing circuits, reducing bill of materials complexity. Consider the 32-QFN package constraints for PCB layout and thermal dissipation requirements. Verify that the external MOSFET selection aligns with the controller's gate drive capabilities.

Hot Swap Controllers Part Context

This part belongs to the LTC4260 series of hot swap controllers from Analog Devices. It is functionally similar to variants like the LTC4260CGN but differs in package and temperature rating. The 'UH' suffix denotes the 32-lead QFN package, while 'I' specifies the industrial temperature range. It serves as a robust solution for protecting sensitive electronics during unexpected power connections.

Hot Swap Controllers Replacement Considerations

LTC4260IUH#TR is available as a tape-and-reel alternative to the tube-packed #PBF version. Both share identical electrical characteristics and pinouts. Verify packaging preferences before substitution. Other family members may offer different packages or temperature ranges but require schematic review.
