LTC4231HMS-2#WTRPBF

Hot Swap Controllers Overview

The LTC4231HMS-2#WTRPBF is a micropower Hot Swap controller designed for safe circuit board insertion and removal from live power supplies. It integrates an internal high-side N-channel switch and supports input voltages from 2.7V to 36V. The device operates within an ambient temperature range of -40°C to 125°C. Key programmable features include circuit breaker settings, current limit thresholds, fault timeout durations, overvoltage protection (OVP), slew rate control, and undervoltage lockout (UVLO). It is housed in a 12-pin MSOP package.

Hot Swap Controllers Feature Summary

• Integrates an internal high-side N-channel switch for direct load connection
• Provides fully programmable protection parameters including current limit and fault timeout
• Supports safe hot insertion and removal from live backplanes or power buses

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe module insertion
• Industrial control systems with live bus architectures
• Automotive electronics utilizing positive low voltage supply rails

Hot Swap Controllers Procurement Notes

Verify the specific suffix WTRPBF indicates tape and reel packaging when sourcing. Confirm the -2 variant designation matches the required pinout or feature set compared to other LTC4231 models. Ensure the operating environment stays within the specified -40°C to 125°C thermal limits. Cross-reference the datasheet for exact electrical characteristics relevant to your power rail specifications.

Hot Swap Controllers Selection Notes

Select this component when micropower consumption is critical during standby or fault states. The integrated high-side switch eliminates the need for external MOSFETs, reducing bill of materials. Consider the programmable nature of the protection features to tailor response times for sensitive downstream loads. Verify compatibility with the system's maximum input voltage of 36V.
