GN25L52-PR

Linear - Amplifiers - Special Purpose

GN25L52-PR is a high performance closed loop current limiting amplifier for DC/AC load protection. It is able to limit current over a wide range from 0.1A to 7.0A and works as a bridge across the load. It is commonly used for active load switching, over-current shut off and braking applications. This device is extremely versatile and can be configured for a variety of applications.

Application Field

GN25L52-PR is widely used in a variety of applications, such as power supplies, motor drives, home appliances, automotive, and industrial control systems. This device is also suitable for other applications requiring current limit control, such as power management, over-current protection, and over-voltage protection. It is also used as an actuator in motor drives, and as an AC power source in AC motor applications.

Working Principle

GN25L52-PR works using a PWM control circuit, capable of operating over a wide range of current levels. A set point voltage is supplied to the amplifier, which is compared to the current through the load. When the current reaches the set point, the amplifier reduces its voltage output and limits the current across the load. The duty cycle of the control voltage is adjusted in order to provide different levels of current limitation.

The amplifier can be operated at variable current limits, depending on the needs of the application. This can be done by adjusting the set point voltage. In addition, GN25L52-PR has an additional feedback loop for closed loop current limiter operation, which can be used to measure the current in the load, and ensure the desired current limit. This allows the device to accurately measure and regulate the current across the load, without the need of any external components.

Conclusion

The GN25L52-PR is a high performance, closed loop current limiting amplifier which provides a wide range of current limiting functions. It is typically used for applications that require precision current limit control, such as power management, over-current protection, and over-voltage protection. The amplifier is also able to be adjusted to provide different levels of current limitation, making it suitable for a variety of applications.
