Hot Swap Controllers datasheet and documents for LTC4231HMS-1#WTRPBF

LTC4231HMS-1#WTRPBF

Hot Swap Controllers Overview

The LTC4231HMS-1#WTRPBF is an automotive-qualified micropower Hot Swap controller designed for safe circuit board insertion and removal from live power supplies. It features an internal high-side switch, adjustable current limiting, and operates within a supply voltage range of 2.7 V to 36 V. The device draws only 4 µA of quiescent current and functions reliably across a temperature range of -40°C to +125°C. Packaged in a 12-lead MSOP with the PBF suffix indicating lead-free composition, it supports surface-mount installation.

Hot Swap Controllers Feature Summary

Automotive-grade reliability certified under AEC-Q100 standards
Micropower operation with ultra-low quiescent current consumption
Integrated high-side switch for controlled power sequencing
Adjustable current limiting for flexible protection settings

Hot Swap Controllers Applications

Automotive electronic control unit (ECU) hot swap modules
In-vehicle infotainment system backplane protection
Telematics and navigation module insertion interfaces
Industrial automotive sensor network controllers

Hot Swap Controllers Procurement Notes

Verify that the specific part number includes the 'HMS' designation to confirm automotive qualification status. Ensure the '#WTRPBF' suffix matches the required tape-and-reel packaging format for automated assembly. Cross-reference the datasheet revision date to ensure compatibility with your design specifications. Confirm RoHS compliance documentation is available for regulatory adherence.

Hot Swap Controllers Selection Notes

Select this component when automotive reliability is mandatory for hot swap applications. The adjustable current limit allows customization for various load requirements without external sensing resistors. Its low quiescent current makes it suitable for battery-backed systems where standby power conservation is critical. The integrated switch simplifies bill of materials compared to discrete solutions.

Hot Swap Controllers Part Context

This part belongs to the LTC4231 family of Hot Swap controllers. The 'HMS' variant specifically denotes automotive qualification, while standard versions may lack AEC-Q100 certification. The 'WPBF' or 'WTRPBF' suffixes indicate lead-free packaging options, with the latter specifying reel packaging for high-volume manufacturing.
