The EVALSTISO62XV1 is available from ST and distributors for $25.00. CMOS digital isolator with giant magnetoresistive (GMR) technology for high speed performance and excellent transient immunity specifications. The STISO621 and STISO621W are both in production, priced from $0.97 for orders of 1000 pieces. High performance level is guaranteed from -40☌ to 125☌ temperature range. The STISO621W in the SO8 wide-body package with 8mm creepage and clearance has VIOTM of 6000V. In the SO8 narrow-body package with 4mm creepage and clearance, the STISO621 has VIOTM of 4800V. With a maximum working isolation voltage (VIOWM) of 1200Vpeak, and high impulse-withstand voltage (VIOTM), galvanic insulation integrity is maintained over time and during any system faults. An X-ray image of an optocoupler, taken from a Silicon Labs document entitled CMOS Digital Isolators Supersede Optocouplers in Industrial Applications. It combines the STISO621 to separate high voltage domains with ST’s high-accuracy STPMS2 metering front-end IC and specific firmware running on an STM32 microcontroller to compute three-phase metrology and power-quality data. An optocoupler is a straightforward device consisting of an LED, an insulating barrier, and a photosensitive semiconductor device (i.e., a photodiode or a phototransistor). The EVALSTPM-3PHISO reference design, specifically designed for three-phase isolated metering-systems use cases, is also available. The IL710-3E is a high-speed CMOS Digital Isolator created by integrating active circuitry and our GMR-based and patented IsoLoop technology. The EVALSTISO62XV1 product evaluation board is available to help accelerate design completion in multiple applications. The design is tested in accordance with VDE0884-10 and UL 1577, the specifications typically applied to isolation devices for high-voltage applications. The STISO621 is suited to a wide range of industrial and consumer applications in power supplies, motor drives, meters, inverters, battery monitors, appliances, fieldbus isolators, size-critical multichannel isolation adapters, and general isolation throughout industrial-automation systems. Typical common-mode transient immunity (CMTI) of 65kV/µs protects the low-voltage side against high switching transients in harsh environments. tegrated’s MAX1493x and MAX1293x family of CMOS digital isolators are specifically designed to meet these requirements and ensure that the circuit arrangement can be implemented successfully, to provide isolation in high-speed SPI communi-cations (Figure 5). 3,0 to 5,5V) with a high isolation voltage. digital isolators for low power operations (2,7 to 5,5V resp. Each has a wide voltage range, allowing level translation between 3.3V and 5.5V circuitry. Analog Devices digital isolator series ADUM. The supply voltages to the two mutually galvanically isolated sides of the STISO621 are independent of each other. Schmitt-trigger inputs to each channel ensure high noise immunity. With two independent unidirectional channels, the device performs as a UART interface handling data in both directions. The STISO621 transfers data between two isolated domains at up to 100Mbit/s, with pulse distortion below 3ns, leveraging ST’s 6kV thick-oxide galvanic-isolation technology. STMicroelectronics has begun volume production of the STISO621 dual-channel digital isolator, launching a new series of high-performance ICs for industrial applications and general optocoupler replacement.
