LTC4214-2CMS#PBF

Hot Swap Controllers Overview

The LTC4214-2CMS#PBF is a negative voltage Hot Swap controller manufactured by Analog Devices Inc. It enables safe insertion and removal of boards from live backplanes while controlling supplies ranging from 0V to -16V. The device features an adjustable current limit, operates within a supply voltage range of 2.7V to 36V, and draws only 4µA of quiescent current. It is housed in a 10-pin MSOP package, supports surface mount installation, and functions reliably across an industrial temperature range of -40°C to +125°C. This component is AEC-Q100 qualified for automotive applications.

Hot Swap Controllers Procurement Notes

Verify the specific suffix #PBF confirms lead-free tape-and-reel packaging compliance with RoHS standards. Confirm the CMS variant matches the required pinout and thermal performance for your PCB layout. Ensure the negative voltage domain aligns with the controller's specified operating range. Check for any recent production change notices affecting package dimensions or material composition.

Hot Swap Controllers Selection Notes

Select this component when managing negative voltage rails in hot swap environments. The adjustable current limit allows customization for different load requirements. The low quiescent current supports battery-backed or energy-efficient designs. Verify that the external N-channel MOSFET selected meets the voltage and current ratings for the specific application.

Hot Swap Controllers Part Context

This part belongs to the LTC4214 series of negative voltage Hot Swap controllers. It complements positive voltage controllers like the LTC4215 to provide comprehensive power management for dual-rail systems. The series is designed for high-reliability applications where board maintenance without power shutdown is critical.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other parts in the LTC4214 family such as the LTC4214-1CMS#PBF, which may differ in specific threshold settings or pin configurations. Cross-reference datasheets carefully to ensure compatibility with existing gate drive circuits and protection thresholds.
