This design reduces isolated channels and leverages analog integration for industrial control and automation applications. These savings reduce power by 16%, solution size by 38%, and cost by 23%. Maxim’s devices used in Corona are designed specifically for harsh industrial environments with operating temperature ranges from -40°C to +125°C, so they are ideal for use in PLCs and other automation applications.
Tony Partow, Senior Business Manager at Maxim, comments: “The MAX31911 incorporated in Corona uses up to 80% less supply current compared to the competition. This demonstrates our expertise in analog integration, coupled with our state-of-the-art high-voltage semiconductor process technologies. Corona is one example of how our reference designs accelerate the design process, while also providing innovative solutions.”
Key advantages:
- Analog integration: reduces isolation channels to four while Maxim’s digital isolator eliminates the need for optoisolators; optimized for 16, 24, and 32 input channel designs, the digital input serializer’s SPI busses can be daisy-chained to further reduce isolation channel count, leading to increased savings,
- Lower power: best-in-class power consumption; uses 16% less power than the traditional design approach,
- Lower cost: uses 38 fewer parts than a traditional design to create a less expensive integrated solution,
- Smaller size: provides 51% fewer components than a traditional design.
Corona’s integrated products:
- MAX31911: industrial, octal, digital input translator/serializer delivers best-in-class power consumption and reduces component count on the board,
- MAX14850: 6-channel digital isolator enables low power consumption and stable high-temperature performance; UL1577, CSA, IEC 60747-5-2 safety certified. Replaces optoisolators, which have limited LED lifespan, with a 5x longer life solution,
- MAX13256: 36V H-bridge transformer driver simplifies isolated power designs.
