Industrial-Strength Full Or Half Duplex Isolated RS-485 Transceivers

Maxim Integrated released their MAX14853/MAX14855 and MAX14943/MAX14949 RS-485 transceivers that include a transformer driver and low drop out (LDO) regulator simplifies power and data isolated designs. The MAX14943 isolated RS-485/PROFIBUS DP transceiver, as well as the MAX14949 transceiver, each provide up to 80% efficiency at 150mA load. Available in full or half duplex isolated RS-485 transceivers, the family supports up to 5kVrms and allows for robust communication up to 25Mbps. The transceivers are ideal for industrial automation, programmable logic controllers (PLC), HVAC, and power meter applications.

Features:

• Ease of design: Simplifies design and provides flexibility through integration; transceivers include a transformer driver and an LDO
• Robust communication: 2.75kVrms and 5kVrms isolation options protect against large differences in ground potential between ports; Robust ±35kV (HBM ESD) on driver outputs/receiver inputs
• High efficiency: Integrated transformer driver provides up to 80% efficiency at 150mA load
• Available in a 16-pin W-SOIC package (11mm x 11mm).
• Specified over the -40-degree Celsius to +105-degree Celsius temperature range.

A Comprehensible Guide to Controller Area Network

A Comprehensible Guide to Controller Area Network by Wilfried Voss represents the most thoroughly researched and most complete work on CAN available in the marketplace. Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications.

The CAN bus is primarily used in embedded systems, and as its name implies, is a network technology that provides fast communication among microcontrollers up to real-time requirements, eliminating the need for the much more expensive and complex technology of a Dual-Ported RAM. This book provides complete information on all CAN features and aspects combined with a high level of readability. Read more...
