With its revolutionary innovative technology, many of its products meet the requirements of AECQ-100 automotive requirements, occupying certain shares in the field of demanding automotive applications.

High isolation and fast overcurrent protection for AC or DC detection in automotive systems: NSM2015 / NSM2016 series Hall effect current sensor chips

NOVOSENSE NSM2015 / NSM2016 Hall effect sensor chips can be used to measure AC or DC current of automotive OBC, DC/DC, PTC heater, charging gun, PDU and other systems. It is a fully integrated, high isolation current sensor with extremely low conduction resistance on the primary side for accurate measurement without external isolation elements.

This series adopts a fixed output mode, the output voltage remains unchanged within a certain range of the supply voltage and does not fluctuate with the fluctuations of the supply voltage. It systematically eliminates the dependence on a high-precision voltage regulator, thereby making the system specification simpler and more cost-effective.

NOVOSENSE’s new chopper and rotating current excitation technology make the zero point temperature drift smaller. Thanks to the precise internal temperature compensation algorithm and offline precision calibration, it can maintain high accuracy over the full operating temperature range, eliminating the need for secondary programming.

In addition, this series features a fast overcurrent protection output with a typical response time of 1.5 us. This fast overcurrent output provides an easy way to detect overload and short circuit events. The overcurrent protection threshold can be set to 75% to 200% of full current. Available in both SOIC16W and SOIC8 widebody packages, with up to 5000Vrms on-resistance, up to 1550Vpk and 1097Vrms operating isolation resistance, and up to 100A current range.

It has the function of suppressing the frequency magnetic field and can be used to detect the rotation angle of auto parts: NSM301x series Hall effect angle sensor chip

NOVOSENSE NSM301x series hall effect sensor chip is a non-contact rotation angle sensor that can be used to detect automotive throttle, chassis height, steering wheel angle, accelerator pedal and valve switch. It can detect in 360° and provide accurate measurement angles at ambient temperatures ranging from -40°C to 125°C.

This series has an automatic gain control (AGC) module that can adjust the gain of the signal path to adapt to various mechanical constraints and magnetic fields. This approach provides maximum flexibility in system design, as it can be integrated directly into existing architectures, ensuring high accuracy.

In addition, it offers 14-bit linear DAC analog output / 12-bit resolution PWM output and 14-bit SPI angle output. It provides angular power with an accuracy of ±1° over the entire temperature range and supports mounting four sections one by one with an accuracy of ±0.2° after mounting four sections.

This series of sensor chips can withstand stray magnetic field disturbances from the X/Y/Z directions: Its four integrated plane Hall elements are only sensitive to magnetic field changes along the Z axis and are immune to stray magnetic field changes in X and Y axis. By differentially amplifying two pairs of opposing Hall elements, four Hall elements generate a sinusoidal signal and a cosine signal for subsequent CORDIC operations. Due to the differential input, the interference of the uniform magnetic field along the Z axis is also eliminated.

High performance and cost-effectiveness for AC and DC bus voltage detection in automotive system: NSI1312x series of isolated voltage sampling chips

NOVOSENSE NSI1312x series isolated voltage sampling chips can be used for AC and DC bus voltage in automotive system. It supports positive and negative voltage input and high impedance input, as well as differential or unidirectional analog output; It can provide up to 5000 Vrms isolation voltage and up to 150 KV/us CMTI, enabling high accuracy and low temperature drift.

Through technology innovation, NMC greatly optimizes the cost of the isolated amplifier so that it supports ±1.2V bidirectional linear input voltage, supports AC and DC voltage acquisition, and realizes phase loss detection for AC input. In addition, it also supports a single-ended output voltage, which can be directly connected to the MCU ADC I/O port, without an additional op-amp as a single-ended differential, while meeting the requirements of cost-effective and high performance, providing a new market competition standard.

With years of accumulation in the field of capacitive technology and its own patent advantages, this series of products has superior EMI performance, with significant advantages over the same type of products in terms of both vertical conductivity and horizontal conductivity.

This series of products is available in both a small narrow body package and a single outlet version, making design easyr.
