LTC4229CG#TRPBF

Hot Swap Controllers Overview

The LTC4229CG#TRPBF is a single 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 with a typical operating current of 2 mA. The device supports an input voltage range of 2.9 V to 18 V and functions reliably across a temperature range of -40°C to +85°C. Packaged in a 24-SSOP housing, it integrates overvoltage protection (OVP) and under-voltage lockout (UVLO). Key programmable features include automatic retry, current limiting, fault timeout, and latch-off fault handling.

Hot Swap Controllers Feature Summary

• Integrates single ideal diode and Hot Swap control functionality for power path management
• Supports programmable automatic retry, current limiting, fault timeout, and latch-off fault modes
• Includes built-in overvoltage protection (OVP) and under-voltage lockout (UVLO)
• Operates without internal switches, requiring external N-channel MOSFETs

Hot Swap Controllers Applications

• Single-rail power supply circuits with ideal diode and Hot Swap functionality
• Power supply switchover systems utilizing prioritizer setups
• Evaluation of Hot Swap controller operation during supply ramp-up and steady state
• Systems requiring controlled power supply switchover with second ideal diode integration

Hot Swap Controllers Procurement Notes

Verify the specific suffix #TRPBF against official documentation to confirm tape-and-reel packaging status. Confirm that the CG variant meets the required industrial temperature range specifications. Ensure compatibility with external N-channel MOSFET selection for the ideal diode and Hot Swap switch implementation. Validate pin assignments against the datasheet schematic for correct circuit integration.

Hot Swap Controllers Selection Notes

Select this component when designing single-channel power paths requiring both reverse current blocking and controlled insertion. The absence of internal switches necessitates the selection of appropriate external N-channel MOSFETs. Consider the 24-SSOP package constraints for PCB layout. Evaluate the need for programmable fault handling features such as latch-off or auto-retry based on system reliability requirements.
