What is high side current sensing?
1. High-side and low-side current sensing refers to the placement of the current-sense resistor: between the positive supply and the load, or between the load and ground.
What is difference between high side and low side current sensing?
In the low-side configuration, the current sense resistor (Rshunt) is placed between the ground terminal of the power supply and the ground terminal of the load. With the high-side method, the shunt resistor is placed between the positive terminal of the power supply and the supply input of the load.
What is low side current sensing?
Low-side current sensing is when the voltage is measured across a sense resistor that is placed between the load and ground. Figure 1 shows the configuration for low side current sensing.
How do you sense your current?
The most common way to measure current is to sense the voltage drop across a shunt or current-sense resistor. To achieve a highly accurate measurement of the current, you’ll need to examine the parametric values of both the resistor and current-sense amplifier.
How do you measure high current?
To measure larger currents, you can place a precision resistor called a shunt in parallel with the meter. Most of the current flows through the shunt, and only a small fraction flows through the meter. This allows the meter to measure larger currents.
What is high side MEP works?

What is high side and low side driver?
High-Side vs. A low-side driver is placed between the load and ground, whereas a high-side driver, shown in 2(b), is placed between the load and the supply voltage. The low-side driver is often used for powertrain-related loads such as motors, solenoids, and heaters.
Why current sensing is required?
Naturally, different devices need differing amounts of electricity so they can function properly—and more importantly, not get damaged from receiving too much power. This is why current sensing is such an important element of the power supply chain.
What is high side and low side in electronics?
A semiconductor switch placed in the upper circuit with respect to an external load is referred to as high-side drive (power supply side), and when mounted in the lower circuit is called low side drive (ground side).
How can we measure the current?
A device called an ammeter is used to measure current. Some types of ammeter have a pointer on a dial, but most have a digital display. To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it.
How is electrical current measured?
The electric current in one part of a circuit is measured with an ammeter, which gives a reading in ampere. To take the measurement, a gap is made in the circuit and the ammeter is connected into that gap, so that the charged particles moving around the circuit must pass through the meter.
What does high side and low side mean?
High Side/Low Side Drive A semiconductor switch placed in the upper circuit with respect to an external load is referred to as high-side drive (power supply side), and when mounted in the lower circuit is called low side drive (ground side).
