SHANGHAI, Aug. 9, 2022 /PRNewswire=KYODO JBN/ --

To cope with the challenge of global climate change and realize the goal of

carbon emission reduction and energy efficiency improvement, the application of

renewable energy and new energy technologies has been rapidly developed in

industrial and automotive fields, which also greatly extends the processing and

transmission scenarios of analog chips, especially in the application field of

NEVs.

Since 2016, NOVOSENSE Microelectronics (hereinafter referred to as NOVOSENSE)

has started to plan the automotive-qualified products. The current three

product directions cover signal sensing, system interconnection and power drive

respectively, with products meeting the AEC-Q100 reliability test standards,

providing comprehensive automotive electronic solutions.

Signal Sensing: To meet the requirements of full combustion and emission

reduction for complying with the upgrading of environmental regulations and

emissions standards, it is often necessary to install temperature manifold

absolute pressure (TMAP) sensor on the intake manifold of the engine of

automobile/motorcycle to quickly and accurately control the air-fuel ratio and

achieve a balance between power performance, fuel economy and emissions.

NOVOSENSE NSP163x series is a type of MEMS absolute pressure wafer based on the

piezoresistive effect of high-sensitivity monocrystalline silicon and is

designed with advanced silicon-silicon bonding CSOI MEMS micromachining

technology, the manufacturing platform of which has been certified by

IAFTF16949, and all wafers (100%) have passed AOI and CP test. NOVOSENSE NSPAS3

is an automotive integrated absolute pressure sensor based on piezoresistive

effect of silicon and using advanced MEMS micromachining technology. The

product adopts automotive-qualified signal conditioning chips to calibrate and

compensate the output of the MEMS die, which can convert pressure signals from

10kPa to 400kPa into analog output signals with a customized output range (0 to

5V). NSP163X series and NSPAS3 series are mainly used for automotive intake

manifold pressure detection and motorcycle intake path pressure detection, as

well as HEV/EV vacuum boost system (VBS) and battery pack pressure detection.

NOVOSENSE NSPAS1 is also a calibrated absolute pressure sensor for gasoline

vehicle intake pressure, NEV vacuum boost and motorcycle TMAP market, which

meets the AEC-Q100 reliability standard.

System Interconnection: The signal conversion between strong and weak circuits

in NEVs has significantly increased the demand for digital transmission

isolation chips. Due to the requirements of safety regulations, common ground

and performance in NEVs, digital isolation chips are required for the motor,

power battery and electric control system (such as OBC, BMS, inverter, electric

air compressor, PTC driver and other high voltage modules). The NOVOSENSE

NSi82x series is a highly reliable multi-channel digital isolator that has been

certified for UL1577 and VDE enhanced safety and supports a variety of

insulation and withstand voltages (3.75kVrms, 5kVrms). The wide supply voltage

range of this series components enables direct connection to most digital

interfaces for easy level switching. NOVOSENSE NCA1021 universal

automotive-qualified LIN transceiver chip can be widely used in bus interface

design of automotive electronic subsystem, such as electric door lock, electric

window, electric seat, electric rearview, glass wiper and seat heater modules,

with the advantages of small interference between lines, less wiring harness,

long transmission distance, and lower cost.

In high voltage current detection for automotive applications, there are

usually two schemes, namely hall based current sensing and shunt based current

sensing. The former has natural isolation characteristics, while the latter

requires additional isolated amplifiers or modulators for electrical isolation.

In comparison, the sampling scheme based on shunt plus isolated

amplifier/modulator has higher accuracy and lower nonlinearity, and the offset

voltage and temperature drift are lower, and it is not easy to be interfered by

external magnetic field, which is preferred by engineers. NOVOSENSE NSi13xx

series chip has the common-mode transient immunity (CMTI) of 150kV/(MU)s, with

good accuracy and compact package design, which is suitable for motor drive,

photovoltaic inverter, uninterrupted power supply and other industrial

applications, as well as high voltage side current and voltage sampling in

onboard charger (OBC), traction inverter and other automotive applications.

Power Drive: In 2022, NOVOSENSE has launched a series of automotive-qualified

chips. NOVOSENSE automotive-qualified LDO NSR31/33/35 series chips are

specially designed for the application scenarios where automotive batteries

power the system. With ultra-low static power consumption of 5uA and low

drop-out voltage, they are suitable for the automotive applications with high

standby power consumption requirements, e.g., to power MCU and CAN/LIN

transceivers in systems to save power and prolong battery life. The series

chips can be used in such application scenarios as IVI and autonomous driving,

body electronics and lighting, inverter and motor control, as well as OBC/DCDC

and BMS. Designed for driving high-reliability load applications, the NSE11409

series intelligent low-side switches can be widely used to drive load elements

such as relays, actuator valves, lighting and heating resistance wires in

automotive and industrial scenarios.

With the rise of the third-generation semiconductor SiC MOSFET, systems with

higher voltage, higher frequency and higher power density are becoming new

development trends. However, in the applications with high voltage and high

frequency, the Power FET in the system is exposed to the risk of damage due to

high dv/dt interference. The high-reliability single-channel isolated gate

driver NSi6601M with the miller clamp protection can solve this problem well.

It can be widely applied to ESS, OBC/DCDC and compressor/inverter and other

applications. In addition, the NOVOSENSE single-channel smart isolated gate

driver NSi661/51 with 10A driving current is also suitable for driving SiC,

IGBT, MOSFET and other power FET, which can be applied to such applications as

NEV traction inverter, generator and boost DCDC.
