The LTC6101 amplifier is an example of a very good unidirectional, high-side current-sense amplifier. But that “unidirectional” is sometimes a problem. It means two things: you can't sense negative ...
Many current-sensing ICs are available for applications that require single-quadrant operation, where positive common-mode voltages are present and current flows in only one direction. There are also ...
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 ...
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 ...
The DIA2240 device is an automotive qualified high precision, bidirectional and zero-drift current sense amplifier with enhance PWN rejection. The device sense drops across the shunt resistor over a ...
The device supports common-mode voltages ranging from -4V to 100V and is AEC-Q100 qualified, making it suitable for use with industrial DC buses and automotive boardnet standards, including 12V, 24V, ...
Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...
