Current-sense amplifiers are not a specific brand but a category of electronic components used for precise current measurement in various applications. Leading manufacturers of these devices include Texas Instruments (USA), Analog Devices (USA), Infineon Technologies (Germany), and STMicroelectronics (Switzerland). These companies produce current-sense amplifiers that serve industries such as automotive, industrial automation, power management, and consumer electronics. Key products in this category include high-side/low-side amplifiers, bidirectional current sensors, and integrated shunt resistors with amplification. The components typically feature low offset voltage, high common-mode rejection, and wide input voltage ranges to accurately monitor current flow in circuits ranging from battery management systems to motor control applications.
