Description
AI
The AFE031 is a low-cost, integrated, powerline communications (PLC) analog front-end (AFE) device 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 1.5 A into reactive loads. The integrated receiver is able to detect signals down to 20 µVRMSand is capable of a wide range of gain options to adapt to varying input signal conditions. This monolithic integrated circuit provides high reliability in demanding powerline communications applications.
The AFE031 transmit power amplifier operates from a single supply in the range of 7 V to 24 V. At maximum output current, a wide output swing provides a 12-VPP(IOUT= 1.5 A) capability with a nominal 15-V supply. The analog and digital signal processing circuitry operates from a single 3.3-V power supply.
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.
The AFE031 is housed in a thermally-enhanced, surface-mount PowerPAD package (QFN-48). Operation is specified over the extended industrial junction temperature range of –40°C to +125°C.
