AMC promotes Polarity-Free and Low-Power RS485 in water, gas and heat meters application
Water, gas, and heat meters need low power consumption as their first priority. The lower quiescent current of interface chip is the more saver meter’s power consumption. AMC promotes the low power RS485 chip, named AZRS6487, which reduced the quiescent current to 60μA and built polarity-free function into the chip. As long as the chip power-on, it immediately completes the polarity detection and judgment, and then executes the polarity correction. When constructing, it doesn’t pay attention to the polarity of the signal line on the bus. Therefore greatly enhances the ease of wiring.
Furthermore, the chip includes a full ESD protection design. Each pin of the chip meets the best ESD protection specifications and has built-in TVS protection at interface pins. Such that, customers’ products can achieve the system-level contact discharge protection to 15kV without additional components.
High Reliable/High Robust RS485 Transceiver IC in Amazing
Amazing dedicated in the professional design for interface IC so as to promote the series of the RS485 transceiver IC embedded with high ESD/high EFT/high Surge/ /digital isolator /low power consumption. Amazing’s RS485 transceiver IC can perform highest surge immunity to ±30A by IEC61000-4-5 (8/20µs) to prevent the RMA. To reduce the failure rate in the process of the production, the HBM (Human Body Model), MM (Machine Model) and Charge Device Model (CDM) of the component level ESD can achieve the military specification in the series of the RS485 transceiver IC. Therefore, Amazing provide the high robust RS485 transceiver IC to reduce the RMA and to improve the yield rate of product.
Amazing RS485 also has 1/8 unit load to connect 256 devices on the bus to perform high-quality communication. Moreover, both the wide common mode range (Vcm = -7V ~ +12V) and high EFT (Electrical Fast Transient) noise immunity are the key features of Amazing RS485 transceiver.
Amazing provide high reliable and high performance RS485 solutions to efficiently simplify the system of the customer.
