The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

Accurate high-side current sensing is essential for automotive-control systems, such as those for EPS (electric power steering), automatic gear shifting, transmission control, engine fuel-injection ...

An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...

Trying to get a circuit to sense its own current consumption can be a little tricky. That said, there are plenty of specialist three and four terminal chips that will sense across a resistor in the ...

Santa Clara, CA and Kyoto, Japan, March 09, 2023 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the BD1421x-LA series of space-saving, high accuracy current sense amplifier ICs for industrial ...

- Growing demand for the current sensing & measurement amplifiers in IoT devices and electric vehicle industries and rising penetration for the smaller or compact sizing factor are propelling market ...

In recent years, the automotive market has seen a growing adoption of 48V systems alongside conventional 5V/12V power supplies, fueled by the rising popularity of electric vehicles. Furthermore, as ...
