Description

The ISOFACE™ 4DIRx4xxHA quad-channel digital isolator family is AEC-Q100 qualified for automotive

applications. It supports data rates up to 40 Mbps and ensures robust data communication over a wide ambient

operating temperature range (-40°C to +125°C). Infineon’s robust Coreless Transformer (CT) technology

provides high immunity against system noise (CMTI of min. 100 kV/µs) and withstands up to 5700 Vrms isolation

voltage (VISO). Four data channels in a PG-DSO-16 wide-body 300 mil package allow simplified and high power

density designs and improve system efficiency with low power consumption. Product variants with different

channel configurations and fail-safe default output states are available.
