The AFE031AIRGZT is an integrated, Powerline Communications (PLC) Analog Front End that is capable of capacitive- or transformer-coupled connections to the powerline while under the control of a DSP or microcontroller. It is ideal for driving low-impedance lines that require up to 1.5A into reactive loads. This monolithic integrated circuit provides high reliability in demanding powerline communications applications. The AFE031 is internally protected against overtemperature and short-circuit conditions. It also provides an adjustable current limit. An interrupt output is provided that indicates both current limit and thermal limit. There is also a shutdown pin that can be used to quickly put the device into its lowest power state. Through the four-wire serial peripheral interface or SPI™, each functional block can be enabled or disabled to optimize power dissipation.
