SHANGHAI, July 11, 2022 /PRNewswire=KYODO JBN/ --

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.

Ultra-low static power consumption, specially designed for automotive battery

power supply systems: NSR31/33/35 series LDO chips

NOVOSENSE NSR31/33/35 series LDO chips are designed for automotive battery

powered system applications with a wide input voltage of 3V to 40V, supporting

transient voltages up to 45V. With an ultra-low static power consumption of 5uA

and low differential voltage, it is ideal for automotive applications with high

standby power consumption requirements. It can power MCU and CAN/LIN

transceivers in standby systems to save power and prolong battery life.

The series of chips have a variety of optional specifications to meet different

design requirements. It is available in a variety of fixed voltage models:

2.5V, 3.3V and 5.0V, as well as output adjustable versions (0.65V to 18V); In
