What Is a Hall Effect Current Sensor?

Hall effect current sensors come with various benefits and applications. Understanding how the hall effect sensors work will help you appreciate their benefits. The first step is to identify the types of magnetic current sensing. There are three types. They include a module that uses a toroid to concentrate the magnetic field around a current-carrying conductor.

The other type is ambient which measures the magnetic field in the air around a PCB trace, bus bar, or other conductors. There is the In-package which measures the magnetic field generated by current flow through the lead frame. Hall effect sensing entails several basics that one needs to understand. The current flows through a lead frame, electrically isolated from the die. The lead frame loop then generates a magnetic field proportional to the current. After that, the precision hall effect current sensor will convert the magnetic field to a voltage signal.

As said earlier, the hall effect current sensing has a number of benefits and applications. Getting to know them will enlighten you on why hall effect current sensors are important. These benefits include in-line PWM and Isolated Ac/DC w/OCP. This is clear evidence of why hall effect current sensing is beneficial. With the applications, you can tell that knowledge about how it works is crucial. You will learn to understand how it accomplishes isolation barrier capability and how it is significant.
