SHANGHAI, July 11, 2022 /PRNewswire/ — In the first half of 2022, NOVOSENSE (an analog and mixed-signal chip design company) launched more than ten new products, which are widely used in automotive, industrial, information and communication and consumer electronics. With its innovative breakthrough technology, many of its products meet the requirements of AECQ-100 automotive requirements, holding certain shares in the demanding field of automotive applications.

High Isolation and Fast Overcurrent Protection for Detecting AC or DC Current in Automotive Systems: NSM2015/NSM2016 Series Hall Effect Current Sensor Chips

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

This series adopts fixed output mode, the output voltage remains unchanged within a certain supply voltage range, and does not fluctuate with the fluctuation of the supply voltage. It consistently eliminates reliance on a high-precision voltage regulator, making system bill of materials simpler and more cost-effective.

NOVOSENSE’s new rotary current chopper and excitation technology reduces zero point temperature drift. Thanks to the accurate internal temperature compensation algorithm and off-line precision calibration, it can maintain high accuracy throughout the entire operating temperature range, eliminating the need for secondary programming.

Additionally, this series features a fast overcurrent protection output with a typical response time of 1.5us. This fast overcurrent output allows easy detection of overload and short circuit events. The overcurrent protection threshold can be set between 75% and 200% of the total current. It is available in widebody SOIC16W and SOIC8 packages, with resistance up to 5000 Vrms, working insulation resistance up to 1550 Vpk and 1097 Vrms, and current range up to 100 A.

Has a common-mode magnetic field suppression function and can be used to detect the rotation angle of automotive parts: NSM301x series hall effect angle sensor chip

NOVOSENSE NSM301x series hall effect angle sensor chip is a non-contact rotation angle sensor, which can be used for the detection of automotive throttle, chassis height, steering wheel angle, etc. steering wheel, accelerator pedal and valve switch. It can detect 360° and to bring precise measurement angles at ambient temperatures ranging from -40°C to 125°C.

This series features an automatic gain control (AGC) module that can adjust the gain of the signal path to accommodate different mechanical stresses and magnetic fields. This approach provides maximum flexibility in system design as it can be integrated directly into existing architectures, providing 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 output with an accuracy of ±1° over the entire temperature range and supports one-by-one four-section mounting with an accuracy of up to ±0.2° after four-section mounting.

This series of sensor chips can resist stray magnetic field interference in the X/Y/Z directions: its four built-in planar Hall elements are only sensitive to magnetic field changes in the Z axis, and immune to changes of stray magnetic field in the X and Y directions. axis. Through the differential amplification of two pairs of opposing Hall elements, four Hall elements generate a sine signal and a cosine signal for subsequent CORDIC operations. Due to the differential input, the uniform magnetic field interference along the Z axis is also canceled.

High performance and cost-effective for AC and DC bus voltage sensing in automotive system: NSI1312x series 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 single-ended analog output; It can provide up to 5000 Vrms of isolation voltage and up to 150KV/us of CMTI, enabling high accuracy and low temperature drift.

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

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

This product series is available in both small narrow body package and single outlet version, which makes designing easier.r.
