PR97743
SHANGHAI, Sept. 9, 2022 /PRNewswire=KYODO JBN/ --
IC design company NOVOSENSE Microelectronics (hereinafter as NOVOSENSE)
announced the launch of 6 new industrial and automotive-qualified chip series,
including isolated sampling, isolated driver, gate driver, non-isolated
high-voltage half-bridge driver, silicon microphone conditioning chip, and
gauge pressure sensor, used in new energy vehicle,industrial, consumer
electronics, medical fields.
1, Driver IC:
Single-channel isolated driver NSi6801 series
NSi6801 single-channel isolated driver is compatible with the optocoupler
input. Compared with the traditional optocoupler gate driver, it has excellent
performance and longer working life, which can work in a higher temperature
environment with shorter propagation delay and less pulse width distortion. It
can be used to drive such power tubes as SiC, IGBT and MOSFET.
The first generation of NSi6801 series was officially launched in early 2021
which could be applied in industrial motor, servo, solar inverter, energy
storage and other fields. With its excellent performance exceeding the
international leading level, it has received positive feedback from markets and
large volume orders from customers. In order to assist customers to reduce
system costs and increase efficiency, the second generation was launched in
August 2022 which is more cost-effective.
Single-channel isolated gate driver NSi66x1A/NSi6601M series
NSi66x1A and NSi6601M single-channel isolated gate drivers launched in 2022 are
suitable for driving SiC, IGBT and MOSFET with both automotive (AEC-Q100
standard) and industrial qualification. They are both widely used in new energy
vehicles, A/C, power supply, solar inverter.
NSi66x1A is a kind of smart driver, providing up to 10A source and sink current
and can directly drive high-power devices without additional Buffer circuits
which is essential for conventional solutions. In addition, NSi66x1A is
equipped with DESAT overcurrent protection, soft-turn-off and Miller clamp,
supporting separate output.
NSi6601M integrates Miller clamp function and is in high isolated withstand
voltage which is more suitable for high frequency, high voltage and high
reliability applications.
Non-isolated high-voltage half-bridge driver NSD1624 series
NSD1624 is a series of non-isolated high-voltage half-bridge drivers launched
recently which could be used to drive power devices such as MOSFET/IGBT.
NOVOSENSE innovatively applies the isolation solution to the high-voltage
half-bridge driver, enabling the high voltage output side to withstand up to
1200V DC voltage, while SW pin can meet the requirements of high DV/DT and
negative pressure peak resistance. It could be widely applied in high
frequency, high voltage and high reliability applications like high-voltage
half-bridge, full-bridge and LLC power topologies.
2, Isolated Sampling IC:
Isolated Sigma-Delta modulator NSi1303/NSi1305 series
The isolated Sigma-Delta modulator NSi1303 and NSi1305 series IC by
NOVOSENSEhas very low offset voltage and temperature drift, high common mode
transient immunity of up to 150kV/us, and 5000Vrms insulation voltage certified
by UL1577. These technologies are applicable to typical applications in the
industrial and automotive markets for current sampling in complex high-voltage
systems. NSi1303 incorporates an internal clock and comes in both manchester
coded (NSi1303Ex) and uncoded (NSi1303M/Dx) versions, while the NSi1305 outputs
data to synchronize with the falling edge of external clock, which fully meets
the different timing requirements from customers.
The NSi1303 is an isolated Sigma-Delta modulator with the internal clock, which
has two options: 10MHz and 20MHz. The output data stream is synchronized with
the internal clock. The corresponding linear differential input signal range of
NSi1303 is ±50mV (full scale ±64mV) or ±250mV (full scale ±320mV). The ±50mV
input range corresponds to 4.9K differential input impedance, and the ±250mV
input range corresponds to 22K differential input impedance.
The NSi1305 is an isolated Sigma-Delta modulator whose output data is
synchronized with the external clock falling edge, and the frequency ranges
from 5MHz to 21MHz. The corresponding linear differential input signal range of
NSi1305 is ±50mV (full scale ±64mV) or ±250mV (full scale ±320mV). The ±50mV
input range corresponds to 4.9K differential input impedance, and the ±250mV
input range corresponds to 22K differential input impedance.
3, Signal chain and sensor:
I2S interface silicon microphone conditioning chip NSC6364
NSC6364 is an I2S interface silicon microphone conditioning chip developed by
NOVOSENSE for wearable devices, smart home appliances and the Internet of
Things. Combining with specific MEMS transducer, the SNR can reach more than
63dB, and it has 3 power modes: sleep, low power, and performance modes, which
can meet the needs of Always Listening to the system in real time. Compared
with the traditional PDM microphone with audio ADC solution, this product can
significantly reduce the system cost and power consumption of acoustic
acquisition channel.
NSC6364 mainly consists of the low noise input buffer, analog-to-digital
converter, digital signal processor, interface circuit, MEMS bias voltage
generation circuit, OTP tuning and power control module. The NSC6364 supports
BIAS and Gain trimming and can be used with mainstream MEMS transducer on the
market. This trimming circuits can tune the final MEMS microphone to tight
+/-1dB as customer requirement.
Gauge pressure sensor NSPGS5 series
Gauge pressure sensor NSPGS5 series of NOVOSENSE adopts CMOS mixed signal
conditioning chip to amplify, calibrate and compensate the MEMS die output,
which can convert the pressure signal from -10kpa to +10kPa into analog signal
with customizable output range (0-5V) and digital I2C signal. In addition, the
built-in MEMS differential pressure die is designed based on the highly
sensitive monocrystal silicon piezoresistive effect and adopts the advanced
silicon-silicon bonded CSOI MEMS micro-machining process. The precision and
stability of the MEMS die during its life cycle are better than 1%F.S..
This series of products is mainly used in ventilator, oxygen generator,
anesthesia instrument, pulmonary function detector, sphygmomanometer and
biosafety cabinet and other medical fields, as well as gas flow detection,
pressure switch and industrial control.
Construction of a complete analog chip product matrix with rapid growth in scale
According to the 2022 semi-annual report released by NOVOSENSE, the company
achieved operating revenue of RMB 793 million in the first half of 2022, a
year-on-year increase of 132.96%.During the reporting period, there was strong
growth in all types of chip products, and the company is now able to offer more
than 1100 models for sale.
