Power Management Integrated Circuit (PMIC) - Gate Drivers are quite a common element in most electronics today. Widely employed in automobiles, cell phones, and other such items, they provide both control and safety to electronic circuits. They have been designed to work with a wide range of voltage levels, allowing them to be used in a variety of systems. The IR2113-2 application field and working principle are just two of the many gate drivers which are in use today. This article will go over both of these topics in a bit more detail.
The IR2113-2 is a gate driver that was developed especially for the medium- and high-voltage power MOSFETs and IGBTs circuits. It includes two independent channels with an integrated MOSFET protection and two protection diodes. This gate driver is ideal for such applications as inverter drives, PFC/PIV converter control systems, and many more. The IR2113-2 also ensures high-speed operation, wide current capability, and excellent thermal performance.

The working principle of the IR2113-2 is quite simple. It comprises of two separate inputs which correspond to two independent gate drives. The gate drive signals are then converted into bipolar signals and routed through an internal circuitry that provides the necessary protections. The converted bipolar signals are then routed to the top and bottom MOSFETS, allowing the gate current to flow in either direction depending on the input signal.

Another important feature of the IR2113-2 is its internal MOSFET protection. This is achieved through the use of an internal current sensing circuit which monitors the drain current. Whenever the drain current exceeds the maximum level, the protection circuit intervenes and halts further current flow. This ensures that the MOSFETs do not get damaged due to excessive current. Additionally, the two protection diodes ensure that the gate does not become overloaded during high input voltages.

In conclusion, the IR2113-2 application field and working principle are quite impressive. This gate driver is able to guarantee high performance and reliable operation in a variety of applications. Additionally, its internal MOSFET protection and two protection diodes ensure a high degree of safety. With its well-rounded features, the IR2113-2 is an excellent choice for electronics applications.
