SHANGHAI, July 11, 2022 /PRNewswire/ — In the first half of 2022, NOVOSENSE (an analog and mixed-signal chip design company) has released more than ten new products, which are widely used in the fields of automotive, industrial, information and communications and consumer electronics. With its innovative breakthrough technology, many of its products meet the requirements of AECQ-100 automotive requirements, holding some shares in the demanding automotive application field.
High Isolation and Fast Overcurrent Protection for AC or DC Current Detection 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 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 measurements without external isolation elements.
This series adopts fixed output mode, the output voltage remains unchanged within a certain range of supply voltage and does not fluctuate with supply voltage fluctuation. It eliminates the dependence on the high-precision voltage regulator systematically, thus making the BOM system simpler and more cost-effective.
NOVOSENSE’s new cutter and rotary current excitation technology make the zero point temperature shift smaller. Thanks to the accurate internal temperature compensation algorithm and precise off-line calibration, it can maintain high accuracy over the full operating temperature range, eliminating the need for secondary programming.
In addition, this series features fast output overcurrent protection with a typical response time of 1.5us. This fast overcurrent output provides an easy way to detect overloads and short circuit events. The overcurrent protection threshold can be set at 75% to 200% of full current. It is available in both wide-body SOIC16W and SOIC8 packages, with on-resistance up to 5000Vrms, operating isolation resistance up to 1550Vpk and 1097Vrms, and current range up to 100A.
It 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
The NOVOSENSE NSM301x series Hall-effect angle sensor chip is a non-contact roll angle sensor that can be used to detect vehicle throttle, chassis height, steering wheel angle, throttle pedal and valve switch. It can detect in 360° and offer accurate measuring 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 different mechanical constraints and magnetic fields. This approach offers maximum flexibility in system design because it can be directly integrated into existing architectures, providing high accuracy.
Additionally, it offers 14-bit DAC linear analog output / PWM output with 12-bit resolution and 14-bit SPI angle output. It provides an angular output with ±1° accuracy over the full temperature range and supports one-by-one four-section assembly with an accuracy of up to ±0.2° after four-section assembly.
This series of sensor chips can resist stray magnetic field interference from X/Y/Z directions: Its four integrated planar Hall elements are only sensitive to magnetic field changes in the Z axis and immune to magnetic field changes lost in X and Y. axis. Through differential amplification of 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 uniform magnetic field interference along the Z axis also cancels out.
High performance and cost-effective for automotive system AC and DC bus voltage detection: 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 isolation voltage and up to 150 KV/us of CMTI, enabling high accuracy and low temperature drift.
Through technology innovation, NMC greatly optimized the cost of the isolated amplifier, so it can support ±1.2V bidirectional linear input voltage, support AC and DC voltage pickup, and realize phase loss detection for AC input. In addition, it also supports single-ended output voltage, which can be directly connected to the MCU ADC input/output port, without additional operational amplifier as a single-ended differential, meeting the requirements of cost-effectiveness and high performance, providing a new standard for market competition.
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 compared to the same type of products in terms of vertical and horizontal conduction.
This series of products is available in both small narrow body packaging and single outlet version, making the design easyr.
