The ISOW1050 device is a isolated controller area network (CAN) transceiver with a built-in isolated DC-DC converter that eliminates the need for a separate isolated power supply in space-constrained isolated designs. The low-emissions, isolated DC-DC meets CISPR 32 radiated emissions Class B standard on a simple two-layer PCB.
The device supports both classical CAN and CAN FD networks up to 5 Megabits per second (Mbps) data rate. The device offers ±58V DC bus fault protection and ±12V common-mode voltage range. Both signal and power paths are 5kVRMS isolated per UL1577 and are qualified for reinforced and basic isolation per VDE, TUV and CQC.
The ISOW1050 device can operate from a single supply voltage of 4.5V to 5.5V . This device supports a wide operating ambient temperature range from –55°C to +125°C and are available in 16-pin DWE (SOIC-16 footprint compatible package) offering a minimum of 8mm creepage and clearance.
The ISOW1050 includes protection features like thermal-shutdown (TSD) and TXD dominant time-out (DTO). ISOW1050 has two variants, the part with V Suffix has an extra VDDL pin to supply the Logic Dies. So if MCU logic is at different supply rail from the power converter input then there is no need to add a level shifter just give the VDDL supply same as the MCU logic supply.
