Texas Instruments  XISOW7841AQDWERQ1

The ISOW7841A-Q1 is an automotive qualified high-performance, quad-channelreinforced digital isolator with an integrated high-efficiency power converter. The low emissionsintegrated DC-DC converter provides up to 650 mW of isolated power at high efficiency and can beconfigured for various input and output voltage configurations. Therefore this device eliminatesthe need for a separate isolated power supply in space-constrained isolated designs.

The ISOW7841A-Q1 device provides high electromagnetic immunity and lowemissions while isolating CMOS or LVCMOS digital I/Os. The signal-isolation channel has a logicinput and output buffer separated by a double capacitive silicon dioxide(SiO2) insulation barrier, whereas, power isolation uses on-chiptransformers separated by thin film polymer as insulating material. If the input signal is lost,the default output is high for the ISOW7841A-Q1 without the F suffix and low for the device withthe F suffix.

These devices help prevent noise currents on data buses, such as CAN, orother circuits from entering the local ground and interfering with or damaging sensitive circuitry.Through innovative chip design and layout techniques, electromagnetic compatibility of the devicehas been significantly enhanced to ease system-level ESD, EFT, surge and emissions compliance. Thehigh-efficiency of the power converter allows operation at a higher ambient temperature. The deviceis available in a 16-pin SOIC wide-body (SOIC-WB) DWE package.
