NOVOSENSE’s comprehensive analog chip product portfolio contributes to the rapid development of NEVs

SHANGHAI, August 9, 2022 /PRNewswire/ — To meet the challenge of global climate change and achieve the goal of reducing carbon emissions and improving energy efficiency, the application of renewable energy and new energy technologies has rapidly developed in the fields of industry and automotive, which also greatly expands the processing and transmission scenarios of analog chips, especially in the application area of ​​NEVs.

Since 2016, NOVOSENSE Microelectronics (hereinafter referred to as NOVOSENSE) began to plan the automotive qualified products. The current three product directions cover signal detection, system interconnection and electric drive respectively, with products meeting AEC-Q100 reliability test standards, providing complete automotive electronic solutions.

Signal detection: To meet the requirements for complete combustion and reduced emissions to comply with upgraded environmental regulations and emissions standards, it is often necessary to install a Temperature Manifold Absolute Pressure (TMAP) sensor on the automobile/motorcycle engine intake manifold to quickly and precisely control the air-fuel ratio and achieve a balance between power performance, fuel economy and emissions. NOVOSENSE NSP163x series is a kind of MEMS absolute pressure wafer based on the piezoresistive effect of high-sensitivity single-crystal silicon, and is designed with advanced CSOI MEMS silicon-silicon bonding micromachining technology, whose manufacturing platform has been certified by IAFTF16949, and all wafers (100%) passed AOI and CP testing. NOVOSENSE NSPAS3 is an automotive integrated absolute pressure sensor based on the 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 array, which can convert pressure signals from 10 kPa to 400 kPa to analog output signals with customized output range ( 0 to 5V). NSP163X and NSPAS3 series are mainly used for automotive intake manifold pressure detection and motorcycle intake path pressure detection, as well as HEV/EV vacuum boosting system (VBS) and detecting battery pack pressure. NOVOSENSE NSPAS1 is also an absolute pressure sensor calibrated for gasoline vehicle manifold pressure, NEV boost and motorcycle TMAP market, which meets AEC-Q100 reliability standard.

System interconnection: Signal conversion between strong and weak circuits in NEVs has greatly increased the demand for digital transmission isolation chips. Due to the requirements of safety regulations, common ground and performance of NEVs, digital isolation chips are required for motor, power battery and electrical 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 isolation and withstand voltages (3.75 kVrms, 5 kVrms). The wide supply voltage range of the components in this series allows direct connection to most digital interfaces for easy level switching. NOVOSENSE Automotive qualified universal LIN transceiver chip NCA1021 can be widely used in automotive electronic subsystem bus interface design, such as electric door lock, electric window, electric seat, electric rearview mirror, windshield wiper and seat heating modules, with the advantages of small interference between lines, less wiring harness, long transmission distance and lower cost.

In high voltage current sensing for automotive applications, there are generally 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 a shunt plus an isolated amplifier/modulator has higher accuracy and lower nonlinearity, and the offset voltage and temperature drift are lower, and it is not not easy to be interfered by external magnetic field, which is preferred by engineers. NOVOSENSE NSi13xx Series The chip has the common mode transient immunity (CMTI) of 150kV/μs, 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 on-board charger (OBC), traction inverter and other automotive applications.

Electric drive: In 2022, NOVOSENSE launched a series of automotive qualified chips. Automotive qualified NOVOSENSE LDO NSR31/33/35 series chips are specifically designed for application scenarios where automotive batteries power the system. With ultra-low static power consumption of 5uA and low dropout voltage, they are suitable for automotive applications with high standby power consumption requirements, for example, to power MCU and CAN transceivers /LIN in systems to save power and extend battery life. The series chips can be used in application scenarios such as IVI and autonomous driving, body electronics and lighting, inverter and motor control, as well as OBC/DCDC and the BMS. Designed to drive high reliability load applications, the NSE11409 series Low-side smart switches can be widely used to drive load elements such as relays, actuator valves, lighting and heating resistor wires in automotive and industrial scenarios.

With the rise of the third generation semiconductor SiC MOSFET, higher voltage, higher frequency and higher power density systems are becoming new development trends. However, in high voltage and high frequency applications, the system power FET is at risk of damage from high dv/dt interference. The high-reliability single-channel isolated gate driver NSi6601M with 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 insulated gate driver NSi661/51 with 10A drive current is also suitable for driving SiC, IGBT, MOSFET and other power FETs, which can be applied to applications such as NEV traction inverter, generator and DCDC boost.
