The ISOW1050(V) family of devices are galvanically isolated CAN transceivers with a built-in isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs. The high-efficiency of the integrate power converter allows for operation at a wide operating ambient temperature range of –55°C to 125°C. The ISOW1050(V) family of device has been designed with enhanced protection features in mind, including soft-start to limit inrush current, over-voltage and under-voltage lock out, overload and short-circuit protection, and thermal shutdown.

Two variants are available for ISOW1050(V) family of devices: ISOW1050 and ISOW1050V. See details of all variants and orderables in Table 1-1. The ISOW1050V an can operate from a single supply voltage of 4.5V to 5.5V by connecting VDDL and VDD1 together on PCB. If lower logic levels are required, 2.25V to 5.5V logic supply (VDDL) can be separated and supplied independent from the power converter supply (VDD1) of 4.5V to 5.5V.
