The IR2130 is a high-voltage, high-speed logic driver IC designed for driving MOSFETs and IGBTs. It comes in 28-pin and 44-pin packages, offering flexibility for various applications. The internal structure of the IR2130 includes six input signals (HIN1, HIN2, HIN3, LIN1, LIN2, LIN3) and three floating ground outputs (H01, H02, H03) for the upper bridge arm, as well as three common ground outputs (L01, L02, L03) for the lower bridge arm in a three-phase inverter circuit. This makes it ideal for driving one complete three-phase full-bridge inverter.

Compared to the IR2103, the IR2130 is essentially three IR2103s combined, making it more powerful and versatile for complex motor control systems. For more detailed information, you can refer to the author’s book “Electric Bicycle Repair from Getting Started to Proficient.”

Another commonly used driver IC is the IR2110, which is widely applied in driving FETs, especially MOSFETs. For specific use cases, the article “Design of Semiconductor Refrigerator Heating and Refrigeration Commutation Circuits” published in the 12th issue of the Electronic World provides valuable insights.

The IR2112 and IR2113 are similar to the IR2110 but differ in key specifications. The maximum VOFFSET for the IR2110 is 500V, while for the IR2112 and IR2113, it is 600V. Additionally, their delay matching times vary: the IR2110 has the largest delay at 100ns, the IR2112 at 30ns, and the IR2113 at 20ns. These differences make each chip suitable for different applications depending on voltage and timing requirements.

The IR2130, IR2110, and IR2112 driver ICs are commonly used in electric bicycles, stepper motor drivers, and other power electronics systems that require efficient control of MOSFETs and IGBTs. Each has its own advantages and is chosen based on the specific design needs of the project.

Several driver chips for MOSFETs and IGBTs have been introduced here, all of which have been tested and applied in real-world scenarios. They serve as practical references for engineers and hobbyists alike. While there are many driver ICs available, it's important to select the right one based on your project’s voltage, current, and timing requirements. Always consider performance, cost, and availability when making your choice.
