Texas Instruments AFE032 Power Line Communications Analog Front End
Texas Instruments AFE032 is designed as a low-cost, integrated, power-line communications (PLC), analog front-end (AFE) device capable of transformer-coupled connections to the power-line while under the control of a digital signal processor (DSP) or microcontroller. TI's AFE032 is ideal for driving high-current, low-impedance lines up to 1.9A into reactive loads. Texas Instruments AFE032 detects signals down to 10μVRMS (G3-FCC mode) and is capable of a wide range of gain options to adapt to varying input-signal conditions.
The monolithic integrated circuit provides high reliability in demanding power-line communication applications. AFE032 is internally protected against overtemperature and short-circuit conditions. The device also provides a selectable current limit. An interrupt output is provided, indicating current limit, thermal limit, and undervoltage. A shutdown pin is also available, and can be used to quickly place the device into the lowest-power state. Each functional block can be enabled or disabled to optimize power dissipation through the serial peripheral interface.
