LTC4219IDHC-12#TRPBF

Hot Swap Controllers Overview

The LTC4219IDHC-12#TRPBF is a hot swap controller from Analog Devices Inc., designed for protecting low-power boards with supply voltages ranging from 2.9V to 15V. It integrates a power MOSFET and current sense resistor in a 16-pin DFN package. The device supports a maximum output current of 5.6A and operates within a temperature range of -40°C to 85°C. It features a quiescent current of 1.6mA and includes thermal limiting, UVLO, programmable current limit, and fault timeout capabilities.

Hot Swap Controllers Feature Summary

• Integrates a hot swap controller, power MOSFET, and current sense resistor into a single compact package.
• Provides precise adjustable current limiting with dedicated ISET pin for dynamic threshold adjustment.
• Includes comprehensive protection mechanisms such as thermal limiting, undervoltage lockout, and fault timeout.

Hot Swap Controllers Applications

• RAID systems
• Server backplanes
• Telecommunications equipment
• Industrial applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the ID variant meets the required industrial temperature range specifications for your application environment. Ensure compatibility with the system's voltage levels before integration.

Hot Swap Controllers Selection Notes

Select this component for designs requiring integrated hot swap protection in space-constrained environments. It is suitable for applications needing precise current control and multiple protection features without external discrete components. Consider the 16-DFN package size for PCB layout constraints.

Hot Swap Controllers Part Context

This part belongs to the LTC4219 series of hot swap controllers manufactured by Analog Devices Inc. The series is known for providing complete solutions for safe board insertion and removal in live backplane systems. The IDHC-12 designation specifies the industrial temperature grade and the 12V internal reference version.

Hot Swap Controllers Replacement Considerations

LTC4219CDHC-12#TRPBF is a commercial grade alternative with a lower operating temperature range. Other variants in the family may offer different voltage ratings or package options depending on specific design requirements.
