Introduction

The IR2133STR is a high-performance semiconductor device intended for use in power electronic applications. IR2133STR is part of a larger family of gate drivers, usually referred to as the family of PMIC Gate Drivers, which are designed to help engineers design and develop power modules that are used in a variety of products. The IR2133STR is a high-speed, high-voltage integrated circuit specifically designed to provide high frequency full-bridge gate drivers, thermal protection, and circuit protection for all kinds of power switching topologies and high current applications, such as power MOSFETs, Insulated Gate Bipolar Transistors (IGBTs), and other power devices.

Application Field of IR2133STR

The IR2133STR is mainly used for power switching topologies for applications where the power devices require full-bridge gate drivers. These applications may include power supply, HVAC, motor control, renewable energy systems, automotive, industrial and home appliances, and the like. The IR2133STR features a high-voltage (up to 600V) drive capability, which is key for power electronic applications. Additionally, the flexibility of the IR2133STR enables secondary side applications as well, which makes it a great choice for applications where a single device can be used to drive both primary and secondary side types of topologies.

Working Principle of IR2133STR

The IR2133STR features two independent low-side gate driver (DRx) and two independent high-side gate driver (DRx). Both the high-side and low-side gate driver in the IR2133STR are integrated with a handful of other components such as a boost diode, current sensing circuit, and cross-conduction protection blocks. The DRx low-side gate drivers are used for controlling the lower side of the power switches of the full bridge power device (e.g. MOSFETs). The DRx high-side gate drivers are used for controlling the higher side of the full bridge power devices (e.g. IGBTs). The IR2133STR also includes an integrated current sense circuit. This circuit provides an indication of the current flowing through the power switches in the full bridged device. This feature allows proactive “turn-on”/”turn-off” control, eliminating the need for high current and/or current-limiting resistors.The IR2133STR features several features that make it especially useful in power electronic applications. For example, the integrated soft-start feature eliminates the need for an external circuit to prevent overshoot, while the low propagation delay eliminates the need for external level shifting circuits. Additionally, the IR2133STR has a current limit and a short circuit protection feature, designed to protect the power device from over-current and short circuit conditions, respectively. Finally, the IR2133STR integrates a Thermal Protection circuit, which is designed to protect the power device from excessive temperature.

Conclusion

The IR2133STR is a powerful gate driver IC, part of a family of PMIC Gate Drivers, designed for use in power electronic applications. The IR2133STR provides integrated full-bridge gate drivers, current sensing circuit, cross-conduction protection blocks, and thermal protection. The advantages offered by the IR2133STR make it a great choice for applications where a single device can be used to drive primary and secondary side types of topologies. The features and flexibility of the IR2133STR make it an excellent choice for a wide range of power switching topologies.
