The TSS521DR from Texas Instruments is a single-chip transceiver specifically developed for Meter-Bus standard (EN1434-3) applications. This device acts as an interface circuit, adjusting different potentials between a slave system and the Meter-Bus master. The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers.
Key electrical specifications include a 3.3V operating voltage and the ability to operate up to 9600 Baud in half duplex for UART protocol. The transceiver features receiver logic with dynamic level recognition and a constant-current sink that is adjustable by resistor. It also includes a power-fail function and a 3.3-V constant voltage source.
Packaged in a 16-SOIC (0.154", 3.90mm Width) surface mount package, the TSS521DR is rated for an operating temperature range of -25°C to 85°C. The device is supplied by the master through the bus, offering no additional load for the slave battery. A power reserve is integrated for delayed switch-off at bus fault.
