Toshiba has launched its first line-up of 10 AEC-Q100 qualified, four-channel digital isolators. The new DCM34xx0<\/strong><\/a> series has been designed to provide common-mode transient immunity (CMTI) of 100kV\/\u03bcs (typ.) at data transmission rates up to 50Mbps in applications like on-board chargers (OBC) and battery management systems (BMS) for hybrid-electric vehicles (HEV) and electric vehicles (EV).<\/p>\n\n\n\n

This new series of digital isolation devices leverages the unique features of Toshiba’s proprietary magnetic coupling technology to deliver high CMTI of 100kV\/\u03bcs (typ.) at supply voltages (VDD1=VDD2) from 3.0 to 5.5V with a common-mode voltage (VCM) of 1500V. This makes them highly resistant to common-mode electrical noise at the input and output nodes, thereby ensuring they can deliver stable equipment control signals for reliable equipment operations.<\/p>\n\n\n\n

These four-channel devices offer flexible configuration options: four forward-only channels, three forward with 1 reverse channel, or two forward with two reverse channels, catering for various design needs. They provide low pulse-width distortion of just 0.8ns (typ.) and are suitable for multi-channel high-speed communication applications, including non-automotive uses such as I\/O interfaces with SPI communications.<\/p>\n\n\n\n

Devices in this series are available in the 16-pin SOIC-16W package and offer stable operation in temperatures ranging from -40\u00b0C to 125\u00b0C.<\/p>\n","protected":false},"excerpt":{"rendered":"
