LTC4231IUD-2#PBF

Hot Swap Controllers Overview

The LTC4231IUD-2#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 36 V and features adjustable current limiting. The device draws a typical operating supply current of 4 uA and functions reliably across an industrial temperature range from -40°C to +85°C. It is housed in a compact 12-lead QFN (3x3 mm) package designed for surface mount technology.

Hot Swap Controllers Feature Summary

• Provides precise control over power-up sequencing and inrush current during hot insertion events
• Features adjustable current limit settings to protect downstream circuitry from overload conditions
• Integrates high-side switch control with comprehensive fault protection mechanisms

Hot Swap Controllers Applications

• Server and storage backplane power distribution
• Telecommunications equipment power modules
• Industrial control system power interfaces

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing components. Confirm that the I-grade designation matches the required operational temperature range for your application environment. Ensure compatibility with the intended board layout for the QFN-12 footprint.

Hot Swap Controllers Selection Notes

Select this component for applications requiring robust hot swap capabilities with low quiescent current consumption. Compare against the HUD variant if extended temperature ranges up to 125°C are necessary. Consider the IMS package option if MSOP form factors are preferred for assembly constraints.

Hot Swap Controllers Part Context

This part belongs to the LTC4231 series of hot swap controllers, which are designed for managing power delivery in systems where live insertion is permitted. The series offers various package options and temperature grades to suit different design requirements while maintaining consistent core functionality.

Hot Swap Controllers Replacement Considerations

Direct substitutes include the LTC4231IUD-1#PBF and LTC4231IMS-2#PBF. Verify pinout compatibility and electrical specifications before implementation.
