The MAX13448E is a ±80V fault-protected, full-duplex RS-485 transceiver.
This device eliminates the need for external fault-protection circuitry, typically polyswitch limiters and zener diodes.
The MAX13448E integrates fault protection on the RS-485 interface pins allowing it to recover from shorts up to ±80V.
The MAX13448E is ideal for architectures such as USB and CAN in which data and power are transmitted along the same cable. Typical applications include industrial, HVAC, and motor-driver control systems.
SUNNYVALE, CA—August 13, 2008—Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the MAX13448E ±80V fault-protected, full-duplex RS-485 transceiver. Capable of withstanding shorts up to ±80V on the RS-485 interface pins, this device 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.
This robust transceiver is slew-rate limited to reduce EMI and reflections on the data bus. It thus allows error-free data transmission at up to 500kbps with a +5V supply, and 250kbps with a +3.3V supply, in environments with high levels of radiated noise. Additionally, hot-swap capability eliminates false transitions on the bus during power-up or hot insertion. It offers ±8kV ESD protection per the Human Body Model.
The MAX13448E operates from a +3.3V to +5V supply. Fully specified over the -40°C to +85°C extended temperature range, it is available in a 14-pin SO package. Pricing starts at $2.20 (1000-up, FOB USA).
