Working Principle of IR6220S

The IR6220S is a monolithic integrated power switch with several of its features on a single chip. It is used as a high-side voltage switch with overvoltage protection (OVP) and current limitation. It is well suited for driving high capacitive loads up to 6 A and blocking voltage up to 55 V.

The IR6220S is an integrated solution for powering up and turning off automotive, industrial and medical systems. The device is designed to provide high switching capability of up to 6A and low power consumption. The device utilizes an N-channel MOSFET and has built-in overvoltage protection (OVP). The built-in OVP feature prevents a higher voltage than the specified one from charge emerging from the input of the device. The device is also provided with an undervoltage protection (UVP) for avoiding damage caused by voltages lower than the specified voltage.

The IR6220S integrates overcurrent protection (OCP) feature inside the device. It monitors the current in the output and when it exceeds the set limit, it sends a signal to terminate the power supply. The device also features over temperature protection (OTP) that helps to reduce power consumption and switch off the power supply when the temperature rises above a certain predefined level. The TTL compatible CMOS logic input of the device enables easy control over the supply.

In short, IR6220S is a powerful and efficient monolithic integrated high-side voltage switch with several features on a single chip. It has wide operating supply voltage range up to 36V and supports current control, current limitation and overvoltage protection (OVP). This device is widely used in various applications such as electronic power steering systems, heating and air-conditioning systems, automotive light applications, industrial control systems, medical equipment and so on.
