LF2136BTR

Overview

The LF2136BTR is a three-phase gate driver IC designed for high-voltage, high-speed applications. It drives N-channel MOSFETs and IGBTs in a half-bridge configuration. The device features three floating high-side drivers operating via bootstrap up to 600V. Output current capability includes a typical source peak drive current of 200mA and a sink peak drive current of 350mA. Outputs are tolerant to negative voltage transients. The component is housed in a 28-pin SOIC package.

Feature Summary

• Provides three independent floating high-side driver channels for three-phase power conversion topologies
• Supports bootstrap operation with maximum voltage tolerance up to 600V for high-side switching
• Delivers robust output drive currents with 200mA source and 350mA sink capabilities for fast switching
• Features output stages tolerant to negative voltage transients for reliable operation in noisy environments

Applications

• Three-phase motor control systems
• High-voltage power supply inverters
• Industrial variable frequency drives

Procurement Notes

Verify the specific suffix 'X' against Littelfuse official documentation to confirm if it denotes a distinct tape-and-reel variant or packaging specification compared to the base LF2136B part number. Ensure the 28-SOIC package dimensions match the design footprint requirements. Confirm active lifecycle status directly with the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing three-phase bridge circuits requiring high-voltage isolation and fast switching speeds. The 600V bootstrap rating suits medium-voltage industrial applications. Evaluate thermal performance within the 28-SOIC package for the intended load current. Ensure the control logic voltage levels are compatible with the driver inputs.

Part Context

This part belongs to Littelfuse's gate driver portfolio, specifically engineered for power management integrated circuits. It serves as a critical interface between low-voltage control logic and high-power semiconductor switches like IGBTs and MOSFETs in automotive and industrial sectors.

Replacement Considerations

Cross-reference with other three-phase gate drivers offering similar 600V ratings and 28-pin SOIC packages. Verify pinout compatibility and electrical specifications such as propagation delay and output current before substituting.
