NCS5651: Power Line Communcation (PLC) Driver, 2 Amp
The NCS5651 is a high efficiency, Class A/B, low distortion power line driver. It is optimized to accept a signal from a Power Line Carrier modem. The device consists of two Operational Amplifiers (opamps). The output opamp is designed to drive up to 2 A peak into an isolation transformer or simple coil coupling to the mains. At an output current of 1.5 A, the output voltage is guaranteed to swing within 1 V or less of either rail giving the user improved SNR.
In addition to the output amplifier, a small-signal opamp is provided which can be configured as a unity gain follower buffer or can provide the first stage of a 4-pole low pass filter.
The NCS5651 offers a current limit, programmable with a single resistor, R-Limit, together with a current limit flag. The device provides two independant thermal flags with hysteresis : a thermal warning flag to let the user know the internal junction temperature has reached a user programmable thermal warning threshold and a thermal error flag that indicates the internal junction temperature has exceeded 150 °C.
The NCS5651 has a power supply voltage range of 6-12 V. It can be shut down, leaving the outputs highly-impedant. The NCS5651 comes in a 20-lead QFN package (4x4x1 mm3) with an exposed thermal pad for enhanced thermal reliability.
