NOVOSENSE Has Launched Multiple Automobile-qualified Chips with Breakthrough Innovation Technology In the first half of 2022
SHANGHAI, July 12, 2022 /PRNewswire-AsiaNet/ --

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 
automotive, industrial, information and communication and consumer electronics 
fields. With its breakthrough innovative technology, many of its products meet 
the requirements of the AECQ-100 automotive requirements, holding certain 
shares in the demanding automotive application field.



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 sense 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 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 range of supply voltage, and does not fluctuate with the 
fluctuation of supply voltage. It eliminates the dependence on high-precision 
voltage regulator systematically, thus making the system BOM simpler and more 
cost-effective.

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

In addition, this series features 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 the full current. It is available in 
both wide-body SOIC16W and SOIC8 packages, with up to 5000Vrms resistance, up 
to 1550Vpk and 1097Vrms working isolation resistance, and up to 100A current 
range.

Has a common-mode magnetic field suppression function, and can be used to 
detect 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 detection of automotive throttle, 
chassis height, steering wheel angle, throttle pedal and valve switch. It can 
detect in 360° and provide accurate measurement angles in 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 provides maximum flexibility in system design because 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 an angular output with 
accuracy of ±1° over the full temperature range, and supports four-section 
fitting one by one with accuracy up to ±0.2° after four-section fitting.

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 the magnetic field changes in the Z axis, and immune to stray magnetic field 
changes in the 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. Because of the differential 
input, the uniform magnetic field interference along the Z axis is also 
canceled out.

High performance and cost effective for detecting AC and DC bus voltage in 
automotive system: NSI1312x series isolated voltage sampling chips

NOVOSENSE NSI1312x series isolated voltage sampling chips can be used to 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 insulation voltage and up to 150KV/us of 
CMTI, enabling high precision and low temperature drift.

Through the innovation of technology, NMC greatly optimized the cost of 
isolated amplifier, so that it supports ±1.2V bidirectional linear input 
voltage, supports the acquisition of AC and DC voltage, and realizes phase loss 
detection for AC input. In addition, it also supports single-end output 
voltage, which can be directly connected to the MCU ADC I/O port, without 
additional operational amplifier as a differential to single-end, while meeting 
the requirements of cost effective 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 have superior EMI performance, with 
significant advantages compared with the same type of products in respect of 
both vertical conduction and horizontal conduction.

This series of products are available in both narrow-body small package and 
single end output version, making the design easier.
