Infineon extends its ISOFACE product portfolio with quad-channel digital isolators for industrial and automotive purposes


Fashionable digital techniques in automotive and industrial purposes require strong, environment friendly, and exact information communication capabilities to make sure optimum efficiency. To fulfill these wants, Infineon Applied sciences is introducing its ISOFACE quad-channel digital isolators, emphasizing a broader portfolio of isolation applied sciences.

The ISOFACE quad-channel digital isolators can be found in two classes. The ISOFACE 4DIRx4xxHA household with AEC-Q100 qualification is designed for automotive purposes corresponding to onboard chargers (OBC), battery administration techniques (BMS), inverters, and motor management. The ISOFACE 4DIRx4xxH household is totally certified in line with JEDEC and is designed for industrial purposes corresponding to renewables, servers, telecom, industrial switch-mode energy provides (SMPS), industrial automation, and remoted serial peripheral interface (SPI). The merchandise are available in a wide-body 300 mil PG-DSO-16 bundle with 4 information channels, offering enhanced isolation and guaranteeing dependable information communications in demanding environments.

The ISOFACE quad-channel digital isolators supply an working provide voltage vary from 2.7 to six.5 V. Even with this vast provide voltage vary, their low present consumption stays environment friendly, capping at 1.6 mA per channel when working at speeds as much as 1 Mbps with a 3.3 V provide voltage and a 15 pF load capacitance. As well as, Infineon’s strong Coreless Transformer (CT) know-how offers excessive immunity in opposition to system noise (widespread mode transient immunity of minimal 100 kV/µs) and withstands as much as 5700 Vrms isolation voltage.

ISOFACE digital isolators are rugged, making them supreme for difficult environments the place excessive temperatures are widespread. For the isolators for automotive purposes, their sturdiness is underscored by their capacity to perform successfully inside Grade I ambient temperature situations, enduring temperatures as little as -40°C and as excessive as +125°C. They will deal with varied environmental challenges, corresponding to voltage transients, electromagnetic interference (EMI), electrostatic discharge (ESD), and electrical disturbances, guaranteeing reliable efficiency. Their exact timing efficiency, owing to low propagation delay and minimal channel-to-channel mismatch, mitigates the chance of corruption and safeguards information integrity. Moreover, their pin-to-pin compatibility provides stability to energy provides, bettering general system reliability.

The isolators are adept at minimising sign noise over a large provide voltage vary, and their exact timing efficiency and compatibility options allow excessive energy density designs. Part-level and system-level certification simplifies security approvals and speeds time-to-market, making ISOFACE digital isolators a precious selection for strong and environment friendly digital techniques.
