What is high side current sensing?
What is high side current sensing?
High-side current-sense amplifiers from Maxim employ a current-sense resistor placed between the positive terminal of the power supply and the supply input of the monitored circuit. The output signal is proportional to the measured high-side current, which can have a common-mode voltage as high as 32V.
What is the purpose of a Current sense amplifier?
A current sense amplifier is a special purpose integrated circuit differential amplifier that is designed to sense the voltage developed across a current shunt and output a voltage proportional to the measured current.
What are Current sense amplifier?
Current sense amplifiers (also called current shunt amplifiers) are special-purpose amplifiers that output a voltage proportional to the current flowing in a power rail.
What is current sensing circuit?
Current sensing refers to the generation of the voltage signal which is related to the current passing in the circuit. A conventional way of sensing current is to insert a resistor in the path of current to be sensitive. Then we can place the sensed resistor anywhere in series with the circuit it maybe load or switch.
What is low side Vs high side?
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.
What is high side network?
The network carrying higher classified information is the high side. The network carrying lower classified information is the low side. The “high side” of the network was classified SECRET. There could potentially be systems where the low side is classified SECRET and the high side is classified TOP SECRET.
How do we sense 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.
What is common-mode voltage?
Technically, a common-mode voltage is one-half the vector sum of the voltages from each conductor of a balanced circuit to local ground or common. An offset from signal common created in the driver circuit, or. A ground differential between the transmitting and receiving locations.
Are sensors AC or DC?
Current sensors, also commonly referred to as current transformers or CTs, are devices that measure the current running through a wire by using the magnetic field to detect the current and generate a proportional output. They are used with both AC and DC current.
Is ammeter a sensor?
A current sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal can be then used to display the measured current in an ammeter, or can be stored for further analysis in a data acquisition system, or can be used for the purpose of control.
What is a high side crash?
A highsider or highside is a type of motorcycle accident characterized by sudden and violent rotation of the bike around its long axis. Incorrect downshifting technique, producing excessive engine braking (even if the motorcycle has a slipper clutch) Applying too much throttle when exiting a corner.
How are high side current sense amplifiers used?
High-side current-sense amplifiers from Maxim employ a current-sense resistor placed between the positive terminal of the power supply and the supply input of the monitored circuit. This arrangement avoids extraneous resistance in the ground plane, greatly simplifies the layout, and generally improves the overall circuit performance.
How are current sense amps from Maxim Integrated?
We offer a wide range of current-sense amplifiers for both high-side sensing and low-side sensing, as well as unidirectional or bidirectional current flow through the sense resistor. Current-sense amplifiers from Maxim feature enhanced input offset voltage specifications. Select from precision, high-voltage, low-power, and space saving amps.
What is the max4172 high side current sense amplifier?
Active in Production. The MAX4172 is a low-cost, precision, high-side current-sense amplifier for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the battery charger’s ground path.
