NCS5651
2 Amp PLC Line Driver
Description 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, RLIM, together with a current limit flag. The device provides
two independent 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 150В°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 (4 Г— 4 Г— 1 mm3) with an exposed
thermal pad for enhanced thermal reliability.
