Maxim Integrated MAX13085ECPA RS-485/RS-422 Transceiver

The MAX13085ECPA is a high-performance, half-duplex transceiver from Maxim Integrated, designed for RS-485 and RS-422 communication protocols. This device is engineered to provide reliable data transmission over long distances and in electrically noisy environments, making it an ideal choice for industrial, network, and automation applications.

The MAX13085ECPA operates from a single 3.3V supply, which helps to conserve power in portable and power-sensitive systems. It features a proprietary AutoShutdown Plus™ function, which automatically enters a low-power shutdown mode when the transceiver senses that the bus is idle, the receiver inputs are open, or the driver inputs are inactive for more than 30 seconds. This feature significantly reduces power consumption when the transceiver is not in active use.

With its extended ESD protection of ±15kV for both the Human Body Model and the IEC 1000-4-2 Air-Gap Discharge Model, the MAX13085ECPA ensures robust performance and resilience in harsh environments. The device's full fail-safe receiver feature guarantees a logic-high receiver output when the receiver inputs are open or shorted, which enhances data integrity under fault conditions.

Moreover, the transceiver supports data rates up to 16Mbps, allowing for high-speed data communication. It also includes a hot-swap capability that prevents glitches on the data line when the device is inserted into a live backplane. The MAX13085ECPA is equipped with a driver output/receiver input that can withstand voltage faults up to ±60V without damage, offering additional protection against line faults.

The MAX13085ECPA comes in a space-saving 8-pin SO package, making it suitable for compact designs. With its thermal shutdown feature, the device protects itself from excessive power dissipation by disabling the driver outputs when the junction temperature exceeds the thermal shutdown threshold.

In summary, the MAX13085ECPA from Maxim Integrated is a versatile and robust RS-485/RS-422 transceiver that provides reliable communication with advanced protective features, ideal for a wide range of applications where data integrity and device protection are paramount.
