Typical Application

The ISOM8610 can be used in numerous industrial applications. For instance, the device can be used on a CAN node design. The ISOM8610 enables a software configurable termination on the CAN bus, needed in networks where new nodes can be continually added. This design can enable or disable termination across CANH-CANL by driving TERM high or low (with appropriate current limiting series resistor on LED emulator pins) through GPIO of the MCU. The farthest terminals on the CAN Bus must be driving TERM = High to enable 120 ohm resistor across the bus, while all other nodes drive TERM = Low. ISOM8610DFG can easily support ±12V common mode with no distortion of CAN signals on the bus. The ISOM8610 also does not require a bulky secondary side isolated power supply, to perform the switching operation. TERM control is galvanically isolated from the CAN lines for reliable system protection. With this architecture, 60 ohm effective termination across the CAN bus can be achieved with flexibility on enabling/disabling a node, with no hardware change. The Top Design Questions About Isolated CAN Bus Design application note contains top answers to design questions about Isolated CAN Bus designs. Finally, the ISOM8610 can be used as an 80V isolated switch when used within the Recommended Operating Conditions.
