The MAX13448E ±80V fault-protected, full-duplex RS-485 transceiver is capable of withstanding shorts up to ±80V on the RS-485 interface pins. It eliminates the need for external fault-protection circuitry, typically polyswitch limiters and zener diodes. The transceiver prevents data from being transmitted during a fault condition, and then resumes normal operation after the fault condition has been removed. This integrated fault protection is useful in architectures such as USB and CAN in which power and data are transmitted along the same cable. The MAX13448E is ideal for industrial, HVAC, and motor-driver control systems.
