Renesas Electronics Corporation introduced the RAA78815x Family of 5V differential RS-485/422 transceivers with electrical fast transient (EFT) immunity ±5000V and ESD protection up to ±16,000V, making these products the ideal solution for noise-sensitive industrial communication networks. The six new full and half duplex ruggedized devices meet both the RS-485 and RS-422 communication standards and are ideally suited for a variety of industrial network, process control network, building automation, long-haul network, and security camera network applications. The new devices build on Renesas current ISL315x 5V RS-485 transceiver family with additional immunity for EFT. In addition to the industrys highest EFT immunity, the RAA78815x family delivers exceptional differential output voltages, featuring 3.1V into the RS-485-required 54? load. The new high-speed transceivers also feature bus leakage currents of maximum 125 µA, representing a true 1/8 unit load to the RS-485 bus. Developers can connect up to 512 transceivers on the same bus without using repeaters and without compromising the RS-485 network standards 32-unit load maximum. As a result of these changes, the RAA78815x family can lower implementation and downtime costs, since a single network can support more nodes with lower likelihood of communications issues due to ESD and EFT overvoltage transients. Key Features of the RAA78815x Family: ±5000V EFT immunity. ±16,000V ESD immunity. 3.1V (typ) into Rd = 54O. Low 125 µA bus current, 550 µA supply current, and 70nA shutdown current. Ultra-small 3x5 mm MSOP and 6 x 8.6 mm SOIC package. Support for multiple data rates and both full (RAA788150, RAA788153, and RAA788156) and half (RAA788152, RAA788155, and RAA788158) duplex modes. The new RAA78815x transceivers are optimal solutions for high-reliability systems. Renesas has designed multiple system architectures using complementary power, analog, and microcontroller offerings to create comprehensive solutions for a variety of applications, including the 48V Position Control Solution and AC Servo Motor Control with Industrial Network Connections, among many others. Renesas Winning Combinations are vetted solutions engineered to help customers accelerate designs and get to market faster.
