Current sense amplifiers A current sense amplifier is a differential amplifier providing an analog output voltage proportional to the current flowing into a load connected on its input. Current sensing solutions add valuable safety and protection features to system designs. They provide information to control current in power systems and avoid overheating and short circuits. Current sensing is also an essential part of energy metering to ensure power-efficiency and minimize environmental impact. Key features The main features of ST's portfolio of current sensing ICs ensure robustness and application safety: -20 to +70 V line monitoring Bidirectional or unidirectional current measurement Integrated solutions for faster design time and reduced bill of materials Integrated EMI filters Pin selectable gain Shutdown function Robust devices that do not require external protection Automotive-grade qualified High-voltage Tolerance to high voltage ranges and protection mechanisms to handle negative voltage are essential in high-power systems such as batteries in electric vehicles. Our current sense amplifiers can work in high voltage applications avoiding additional external protections components and simplifying the final schematic. Precision / high-accuracy Using a precision current sense amplifier allows designers to measure small voltage drops across shunt resistors with minimal error. Small shunt resistors values are necessary to minimize the power dissipation. Thanks to highly accurate current measurements, precision current sense amplifiers offer a better efficiency and thermal performance.
