NCS5650

2 Amp PLC Line Driver
The NCS5650 is a high efficiency, Class A/B, low distortion power
line driver. Its design is optimized to accept a signal from a Power Line
Carrier modem. The output stage is designed to drive up to 2 A peak
into an isolation transformer or simple coil coupling to the mains. At
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. Power
supply options are single−sided 6 V to 12 V and dual balanced
$3.0 V to $6.0 V. The input stage contains an operational amplifier
which can be configured as a unity gain follower buffer or used to
provide the first stage of a 4−pole low pass filter. In addition the
NCS5650 offers a current limit programmable with a single resistor,
R−Limit, 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. In shutdown mode the NCS5650
output goes into a high−impedance state. The NCS5650 comes in a 20
lead QFN package (4x4x1mm) with an exposed thermal pad for
enhanced thermal reliability.
