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, R
LIM
, 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 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 (4
×
4
×
1 mm
3
) with an exposed
thermal pad for enhanced thermal reliability.

Pin Description
1. The principal purpose of pin 2 is to facilitate the implementation of the 4th−order low pass filter when operating on single−sided supply by
providing a virtual common at mid−supply. When operating on dual balanced supplies, Pin 2 must be left floating and the external common
of the dual supplies should be used for the filter implementation
