The IR2130 is a high-voltage, high-speed logic driver IC designed specifically for MOSFET and IGBT power devices. It comes in two package types: 28-pin and 44-pin. The internal architecture of the IR2130 allows it to control both high-side and low-side switches in a three-phase inverter circuit. This makes it ideal for applications such as motor drives, power supplies, and electric vehicle systems.

The IR2130 features six input signals—HIN1, HIN2, HIN3 for the high-side, and LIN1, LIN2, LIN3 for the low-side. These inputs drive three high-side outputs (H01, H02, H03) with floating ground and three low-side outputs (L01, L02, L03) with common ground. This configuration enables the IR2130 to control one complete three-phase full-bridge inverter. For more detailed technical insights, readers can refer to the author’s book “Electric Bicycle Repair from Getting Started to Proficient.” As shown in the block diagram, the IR2130 is similar to the IR2103 but functions like three IR2103s combined.

Another commonly used driver IC is the IR2110, which is also widely applied for driving 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 useful guidance. The IR2112, IR2113, and IR2110 are very similar in function, but they differ in key specifications. For example, the IR2110 has a maximum VOFFSET of 500V, while the IR2112 and IR2113 support up to 600V. Additionally, the delay matching between channels varies: the IR2110 has the largest delay at 100ns, the IR2112 at 30ns, and the IR2113 at 20ns.

The IR2130, IR2110, and IR2112 driver ICs are widely used in various applications, including electric bicycles, stepper motor drivers, and other systems requiring the control of MOSFETs and IGBTs. Their versatility and performance make them popular choices among engineers and hobbyists alike.

In this article, I have introduced several driver chips suitable for driving MOSFETs or IGBTs. All of these have been tested and used in real-world applications, making them valuable references for readers. While there are many driver ICs available on the market, it's important to choose the right one based on your specific project requirements. Understanding the differences in voltage ratings, delay times, and package types will help you make an informed decision when designing your system.
