LTC4229IG#TRPBF

Hot Swap Controllers Overview

The LTC4229IG#TRPBF is an ideal diode and Hot Swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.9 V to 18 V and draws a typical supply current of 2 mA. The device is housed in a 24-SSOP package with dimensions of 0.209 inches (5.30 mm) width, designed for surface mount installation. It supports an operating temperature range from -40°C to 85°C. Key electrical features include overvoltage protection (OVP) and under-voltage lockout (UVLO). Programmable functionalities encompass automatic retry, current limiting, fault timeout, and latch-up fault modes.

Hot Swap Controllers Feature Summary

• Integrates single-channel ideal diode and Hot Swap control functions using external N-channel MOSFETs
• Provides programmable protection against overcurrent, overvoltage, and undervoltage conditions
• Supports configurable fault response mechanisms including automatic retry and latch-up modes

Hot Swap Controllers Applications

• Evaluation of power supply ramp-up and steady-state operation modes
• Implementation of power supply switchover systems using prioritizer setups
• Single-rail circuit designs requiring ideal diode and Hot Swap functionality

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging configuration when sourcing components. Confirm that the IG designation corresponds to the industrial temperature grade (-40°C to 85°C) required for the application environment. Ensure compatibility with the 24-SSOP footprint during PCB layout verification. Cross-reference official datasheets for precise pin assignments including CPO, DTMR, /EN, /FAULT, FB, and FTMR to guarantee correct circuit integration.

Hot Swap Controllers Selection Notes

Select this component for applications requiring combined ideal diode rectification and controlled power sequencing. The device necessitates external series N-channel MOSFETs rather than providing internal switches. Consider the 2.9 V to 18 V input range and 2 mA supply current for power budget calculations. Evaluate the need for programmable fault handling features such as auto-retry or latch-up based on system reliability requirements.

Hot Swap Controllers Part Context

The LTC4229 belongs to the family of ideal diode and Hot Swap controllers produced by Analog Devices Inc. This category of integrated circuits manages power path switching and protection without the voltage drop associated with standard diodes. The controller coordinates external MOSFETs to prevent reverse current flow and manage inrush currents during power application, ensuring safe hot insertion and removal of power modules.
