LTC4283IUHF#TRPBF

Hot Swap Controllers Overview

The LTC4283IUHF#TRPBF is a negative voltage hot swap controller designed for high-performance power distribution. It features an I2C interface and an onboard gear-shift analog-to-digital converter (ADC) to monitor board current, voltage, power, energy, and fault status. The device supports programmable auto-retry, current limit, fault timeout, latched fault, overvoltage protection (OVP), and undervoltage lockout (UVLO). It operates within a supply voltage range of 10.8V to 12V and functions across an operating temperature range of -40°C to 85°C.

Hot Swap Controllers Feature Summary

• Integrates an I2C interface with an onboard gear-shift ADC for comprehensive monitoring of electrical parameters including current, voltage, power, and energy.
• Provides programmable protection features such as auto-retry, current limiting, fault timeout, latched faults, overvoltage protection, and undervoltage lockout.

Hot Swap Controllers Applications

• Negative voltage hot swap applications
• Power distribution systems requiring detailed energy monitoring
• Board-level power management where I2C communication is required

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the component is intended for negative voltage hot swap control, distinct from positive voltage counterparts in the Analog Devices portfolio. Ensure compatibility with the 10.8V to 12V supply range and I2C bus requirements during integration planning.

Hot Swap Controllers Selection Notes

Select this component when negative voltage hot swap capability is required alongside precise energy and power monitoring via I2C. The integrated gear-shift ADC offers flexibility in measurement resolution. Consider the 38-lead QFN package constraints and the -40°C to 85°C industrial temperature range for environmental suitability.

Hot Swap Controllers Part Context

This part belongs to the LTC4283 series of negative voltage hot swap controllers manufactured by Analog Devices Inc. It is distinguished by its advanced monitoring capabilities through an integrated ADC and I2C interface, differentiating it from simpler hot swap controllers that lack detailed telemetry or communication interfaces.

Hot Swap Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and functional compatibility if considering alternative negative voltage hot swap controllers from other manufacturers.
