Novosense announces quad-channel digital isolators for industrial and automotive applications

Novosense Microelectronics has expanded its family of digital isolators with quad-channel devices that provide the performance and protection demanded by the latest industrial and automotive applications. The new NSI824xWx high-reliability digital isolators provide compact and efficient protection and level shifting in applications ranging from solar inverters and energy storage to industrial automation and electric vehicles.

UL1577-qualified for safety, the ultra-wide body NSI824xWx industrial and automotive grade isolators combine robust EMC performance with high levels of protection against system-level electrostatic discharge (ESD), electrical fast transients (EFTs) and voltage surges. Each device offers an insulation voltage up to 8kVrms, chip-level ESD HBM protection to ±8kV and common-mode transient immunity (CMTI) up to 200kV/μs.

The isolators are available with options for four forward channels, three forward and one reverse channel or two forward and two reverse channels. Default output state on power loss can be set to low or high. Channel speeds up to 150Mbps are supported, while a wide input voltage range of 2.5V to 5.5V simplifies level shift operations by ensuring compatibility with a wide variety of digital interfaces. A low power consumption of 1.5mA per channel (at speeds of 1Mbps) helps designers to meet system efficiency targets.

As with all members of the range, the latest NSI824x devices employ an adapted capacitive isolator technology in which the digital signal undergoes modulation by an RF carrier generated on the transmitter side and is then demodulated on the receiver side. Subsequently, the signal is transmitted via a capacitive isolator and demodulated on the receiver side. Use of Novosense’s proprietary Adaptive OOK modulation technology is key to robust performance, which includes high noise resistance and low EMI.

The devices are supplied in an SOWW16 package, can support 15mm creepage distance and operate across a wide temperature range of -55℃ to 125℃, and are fully compliant with all relevant UL, CQC, CSA and VDE safety standards. In industrial automation systems, they can be used for industrial control, industrial motor drive applications, industrial transportation, instrumentation, industrial field instruments, isolated SPI, RS232, and RS485 applications, universal multi-channel isolators, and motor control. Automotive targets will include automobile sensors, electric drives and power supplies and battery management systems.

Next-Gen ethernet switches from Microchip feature time sensitive networking and scalable port bandwidths

The growth of the industrial automation market encompasses innovative technologies like Machine Learning (ML) and robotic systems. Embedded solutions with deterministic communication are essential for industrial automation applications to control, monitor and process data. To provide designers with a reliable and robust network solution with deterministic communication, Microchip has announced its next-generation of LAN969x Ethernet switches with Time Sensitive Networking (TSN), scalable bandwidths from 46 Gbps to 102 Gbps and a powerful 1 GHz single-core Arm® Cortex®-A53 CPU.

For applications that require greater redundancy, the LAN969x Ethernet switches can be configured with High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP). HSR and PRP are hardware protocols that provide zero-loss redundancy in Ethernet networks. The LAN969x Ethernet switches support multiple HSR and PRP Redundancy Box (RedBox) instances that can operate in parallel and in series, as well as at Ethernet port speeds from 10 Mbps to 10 Gbps.

The LAN969x can implement a QuadBox, which is a function that connects two HSR networks to each other. This feature is particularly useful in applications where high reliability and zero downtime are critical. Alternative solutions that implement a QuadBox typically require multiple different components that can drive up design complexity and system costs.

“Prior to the introduction of Microchip’s LAN969x Ethernet switches, customers who wanted to implement TSN and HSR/PRP features required multiple ICs. Microchip’s new LAN969x solution is a single chip that can reduce the number of components and system level costs,” said Charles Forni, vice president of Microchip’s USB and networking business unit. “These devices are also supported with our VSC6817SDK IStaX Linux® application software package that can enable designers to quickly bring products to market.”

The LAN969x Ethernet switches are highly configurable with options of up to 30 ports. The Ethernet ports support multiple interfaces including RGMII, SGMII, QSGMII, USGMII, and USXGMII. The LAN969x family targets secure and safety-critical applications where high- port-count 10M/100M/1G/2.5G/10G switching links are required.

The LAN969x family is available with security add-ons such as secure boot and secure firmware execution based on the customer’s root-of-trust manufacturing process. Security is provided through Ternary Content Addressable Memory (TCAM)-based frame processing using a Versatile Content Aware Processor (VCAP), Arm Trusted Firmware methodology for fast secure boot, crypto libraries and hardware security accelerators for boot and code encryption, and one-time programmable immutable key storage.

The new family of LAN969x mid-range Ethernet switches rounds out Microchip’s portfolio of TSN switches. The SparX-5i family supports up to 64-ports and 200 Gbps of switching bandwidth, while the LAN9662 and LAN9668 support from 4 to 8 ports and 4 to 11 Gbps of switch bandwidth.

The LAN969x family of Ethernet switches is supported by the EV23X71A Evaluation Board. Other resources include the IStaX VSC6817SDK Linux Application Software Package to support TSN standards and HSR/PRP redundancy.
