The MAX3471CUA+ is an integrated circuit (IC) component designed to provide a complete solution for implementing USB-to-Isolated RS-485/RS-422 communication. It features a high-speed USB interface with up to 12Mbps data rate and supports both full-speed (12Mbps) and low-speed (1.5Mbps) USB modes.
Key features of the MAX3471CUA+ include:
1. USB 2.0 Compliance: The IC is fully compliant with the USB 2.0 specification, allowing for reliable and high-speed data transfer between the USB host and the RS-485/RS-422 network.
2. Isolated RS-485/RS-422 Interface: The MAX3471CUA+ incorporates an integrated isolation barrier to provide robust electrical isolation between the USB interface and the RS-485/RS-422 network. This isolation protects both the USB host and the connected devices from ground loops and voltage spikes.
3. Auto-Direction Control: The IC features an auto-direction control function, eliminating the need for external direction control pins or software. The device automatically controls the direction of data transmission based on the USB bus state, simplifying the implementation of half-duplex communication.
4. Low Power Consumption: The MAX3471CUA+ is designed for low power operation, consuming minimal power from the USB bus. This feature makes it suitable for battery-powered and power-limited applications
