Introduction

RT7020GS is a high-performance inter-isolated dc-dc converter IC that can be used for multiple purposes, including controlling the switching of loads, providing accurate and stable current, and regulating the supply voltage in power management, communications and industrial applications.

Application Field

The RT7020GS is a power management IC (PMIC), specifically, a gate driver. Gate drivers are specially designed to drive MOSFETs and IGBTs, which are essential components of power supplies and DC power systems.Gate drivers provide high current amplification and isolation in order to reduce the driving voltage of big MOSFETs and IGBTs, making driving the power stage of sensitive electronics possible. Gate drivers are used in a wide range of applications, including motor controllers, remote power and control, power supply design, communications systems, renewable energy systems, automotive systems, and industrial and medical devices.

Key Features

The RT7020GS is a high-performance gate driver IC specifically designed to provide high accuracy and stable current in high-density power systems. It offers several key features which make it well suited for use in a wide range of applications where stable, precise current is required. First, the RT7020GS operates at an extremely wide input voltage range, from 2.3 to 20V, making it compatible with many different power sources. It can provide up to 500mA of current and supports up to 12Vlogic-level MOSFETs.The RT7020GS also features overcurrent protection, which helps prevent damage to the power stage if a MOSFET or IGBT fails. The ambient temperature range is also significantly expanded, which helps optimize thermal performance and further enhances reliability.

Working Principle

The RT7020GS is based on the working principle of a DC-DC converter with inter-isolated power supplies. This principle allows the IC to be used to provide DC isolation between different components in power systems, such as between different stages of the power supply, between the power stage and system, and between the power supply and the load.The working principle of the RT7020GS is based on the Little-Hall Effect. The RT7020GS can be used to provide a clean output voltage by regulating the current in the power circuit and regulating the switching of the MOSFETs.It works by regulating the gate current and driving the gate-source voltage of the MOSFETs. By controlling the gate current and the gate-source voltage, the RT7020GS can control the on/off operation of the MOSFETs, allowing it to regulate the output voltage in the power supply.The RT7020GS also features under-voltage lockout protection and thermal overload protection. These features are designed to prevent the IC from being damaged in the case of overvoltage or short-circuit conditions, and to protect the power stage from thermal damage due to prolonged operation.

Conclusion

The RT7020GS is a high-performance gate driver IC that is used to drive MOSFETs and IGBTs in a variety of power supplies and systems. It works on the principle of a DC-DC converter with inter-isolated power supplies, using the Little-Hall Effect to regulate the current in the power circuit and the switching of the MOSFETs.The RT7020GS offers several key features, including wide input voltage range, high current amplification, overcurrent protection, temperature range expansion, and more. It is an ideal choice for controlling switching loads and providing stable current in high-density power systems.
