ISOW784x/ISOW784x-Q1 Reinforced Digital Isolators

Texas Instruments ISOW784x/ISOW784x-Q1 Reinforced Digital Isolators are high-performance, quad-channel reinforced digital isolators with an integrated high-efficiency power converter. The integrated DC-DC converter provides up to 650mW of isolated power at high efficiency and can be configured for various input and output voltage configurations. These devices eliminate the need for a separate isolated power supply in space-constrained isolated designs. The ISOW784x/ISOW784x-Q1 provides high electromagnetic immunity and low emissions while isolating CMOS or LVCMOS digital I/Os. The signal isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO₂) insulation barrier. Power isolation uses on-chip transformers separated by thin-film polymer as the insulating material. The Texas Instruments ISOW784x-Q1 devices are AEC-Q100 qualified for automotive applications.
