10.2 Typical Application

For industrial applications, the ISOM871x devices can be used with a Texas Instruments mixed signal microcontroller, digital-to-analog converter, transformer driver, CAN transceiver, buffer, and voltage regulator to create an isolated CAN communication system. The different components of this typical schematic, like the microcontroller, transceiver, optional buffer, and power supply, can be replaced to create isolated RS-485, UART, SPI, GPIO, and other isolated signal communication systems. Additionally, ISOM871x devices can be used to isolate other signals within its Recommended Operating Conditions, including PWM power supply feedback signals.
