The need to accurately measure a dynamic current is critical in a wide variety of applications, such as monitoring or charging batteries, creating a current controlled feedback loop for a power supply or motor, or simply to monitor current levels for safety reasons. Our current sense amplifiers provide a high-flexibility, high-precision solution to maximize efficiency and reliability with a zero-drift architecture, which makes your design more robust across a wide range of environmental conditions and applications.
We provide a variety of devices to monitor power, voltage, current, zero cross detection and energy accumulation. Whether you need to monitor a DC voltage or a single- or poly-phase AC line, our innovative and easy-to-use products provide highly integrated solutions to meet your design challenges.
The HV780x series of high side current monitors offers a wide input voltage range and low quiescent current, making these devices well suited for a variety of offline, battery-powered and portable applications.
