NOVOSENSE launched the automotive-qualified integrated current sensor NSM2019 featuring low impedance and high isolation

SHANGHAI,June 20,2023 -- The NSM2019 integrated current sensor chip fromNOVOSENSE provides a fully integrated,highly isolated current sensor solution with extremely low internal primary conductor resistance,providing accurate current measurement without external isolation components for a wide range of applications for AC or DC current measurement in automotive and industrial systems.

The NSM2019 is a perfect complement to the NSM201x series of integrated current sensors already in production,with a unique package design that achieves industry-leading primary conductor resistance as low as 0.27mΩ and increased continuous current capability to 100A,further reducing the difficulty of heat dissipation design in compact systems.

NSM2019 is available in automotive-qualified and industry-qualified versions. The automotive-qualified version meets the reliability requirements of AEC-Q100 Grade 0 and can work in the harsh environment of -40 to 150℃.

NSM2019 adopts fixed and pseudo-differential output modes,and the output voltage does not fluctuate with the supply voltage. It eliminates the dependence on high-precision voltage regulator systematically,thus making the system BOM simpler and more cost-effective.

In addition,thanks to the precise temperature compensation algorithm inside the chip and offline calibration,the NSM2019 can maintain a high accuracy in the full operating temperature range requiring no user programming,with a sensitivity error of <±2% and a zero error of <±10mV in the full temperature range.

The NSM2019 features fast overcurrent protection with a typical response time of 1.5μs. The default overcurrent protection threshold ranges from 75% to 175% of full scale current.

NSM2019is available for sample. For sample application or order,please email to sales@novosns.com. For more information,click www.novosns.com.
