The monolithic integrated circuit provides high reliability in demanding power-line – ARIB STD-T84, FCC communication applications. – FSK, SFSK, and NB-OFDM The AFE032 transmit power amplifier operates from a • Conforms To: single supply in the range of 7 V to 24 V. At typical – EN50065-1, -2, -3, -7 load current (IOUT = 1.5 APEAK), a wide output swing – FCC, Part 15 provides a 12-VPP capability with a nominal 15-V supply. – ARIB STD-T84 • Standards: The device is internally protected against overtemperature and short-circuit conditions. The – G3, PRIME, P1901.2, ITU-G.hnem device also provides a selectable current limit. An • Programmable Tx Low-Pass Filters and interrupt output is provided, indicating current limit, Rx Band-Pass Filters thermal limit, and undervoltage. A shutdown pin is • Integrated Power-Line Driver with Thermal and also available, and can be used to quickly place the device into the lowest-power state. Each functional Overcurrent Protection block can be enabled or disabled to optimize power • Low-Power Consumption: dissipation through the serial peripheral interface – 50 mW (Receiver Mode) (SPI), • Receive Sensitivity: 10 μVRMS (Typ) The AFE032 is housed in a thermally-enhanced, • Four-Wire SPI™ Interface surface-mount, PowerPAD, QFN-48 package. Operation is specified over the extended industrial • Three Integrated Zero-Crossing Detectors junction temperature range of –40°C to +125°C. • Package: QFN-48 PowerPAD™ • Extended Temperature Range: –40°C to +125°C APPLICATIONS • eMetering • Home Area Networks • Lighting • Solar • Pilot Wires and EVSEs DESCRIPTION The AFE032 is 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. This device is ideal for driving high-current, low-impedance lines up to 1.9 A into reactive loads. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PowerPAD is a trademark of Texas Instruments. 3 Illinois Capacitor is a trademark of Illinois Capacitor, Inc. 4 SPI is a trademark of Motorola Inc. 5 All other trademarks are the property of their respective owners.
