LF21814NTR

Overview

The LF21814NTR is a floating high-side gate driver designed for bootstrap operation up to 600V. It drives two N-channel MOSFETs or IGBTs in a half-bridge configuration. The device integrates voltage regulators and control circuits onto a single chip to simplify power management.

Feature Summary

Supports floating high-side driver operation via bootstrap method
Capable of driving dual N-channel MOSFETs or IGBTs in half-bridge topology
Integrates multiple voltage regulators and control circuits on one chip

Applications

Half-bridge power converter stages
High-voltage motor drive systems
Industrial power supply inverters

Procurement Notes

Verify the exact part number against Littelfuse official documentation, as distributor listings may contain typos or misclassifications. Confirm the datasheet matches the specific suffix and package type before procurement to ensure compatibility with the intended 600V application requirements.

Selection Notes

Select this component when a dedicated high-side driver for half-bridge configurations is required. Ensure the system design supports bootstrap voltage generation. Verify that the integrated regulator outputs meet the gate drive requirements of the selected MOSFETs or IGBTs.

Part Context

This component belongs to the Littelfuse gate driver family, specifically categorized under PMIC - Power Management ICs. It serves as a critical interface between low-voltage control logic and high-voltage power switches in power electronics applications.

Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic cross-references are not recommended due to specific electrical characteristics and pinout requirements.
