IR2133JTR

Gate Driver Overview

The IR2133JTR is a three-phase gate driver IC designed for driving IGBTs and N-channel MOSFETs. It integrates six independent half-bridge drivers within a single package, supporting high-side voltages up to 600 V. The device features a wide supply voltage range of 10 V to 20 V for both the logic (VCC) and bootstrap (VBS) supplies. Key electrical parameters include a source output current of 0.25 A and a sink output current of 0.5 A. Propagation delays are specified with a maximum turn-on delay of 1 µs and a maximum turn-off delay of 950 ns. The component operates reliably across an extended temperature range from -40 °C to +125 °C.

Gate Driver Feature Summary

• Integrates six independent half-bridge drivers for complete three-phase bridge control
• Includes undervoltage lockout protection for both logic and bootstrap supply rails
• Supports direct interface with standard CMOS or TTL logic inputs
• Provides functional junction isolation for high-side floating drive applications

Gate Driver Applications

• Three-phase motor drives and inverters
• Switched-mode power supplies requiring isolated gate drive
• Industrial AC and DC servo motor controllers
• High-voltage power conversion systems

Gate Driver Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the component status is active, as some variants in this family may be obsolete. Ensure compatibility with the target PCB footprint, typically PLCC-44, during procurement planning. Check for moisture sensitivity level requirements if storage conditions exceed manufacturer recommendations.

Gate Driver Selection Notes

Select this component when a monolithic solution for three-phase bridges is required to reduce board space. It is suitable for designs needing integrated bootstrap diodes and UVLO protection. Consider the 600 V high-side rating for medium-voltage applications. Verify that the 0.25 A source current meets the gate charge requirements of the selected power devices at the intended switching frequency.

Gate Driver Part Context

This part belongs to Infineon's legacy line of high-voltage gate driver ICs. It serves as a comprehensive solution for three-phase applications, eliminating the need for discrete bootstrap components. The device simplifies design by integrating level shifting and protection features into a single package, commonly used in industrial and consumer power electronics.

Gate Driver Replacement Considerations

The IR2133JPbF is a pin-compatible lead-free variant of this component. Verify that the replacement matches the exact package dimensions and thermal characteristics. Ensure that any substitute maintains the same 600 V high-side voltage rating and logical input compatibility.
