Line driver targets PLC communciations tasks
ON Semiconductor
NCS5650 line driver
ON Semiconductor has introduced the NCS5650 line driver device targeted at power line carrier (PLC) communications applications such as smart metering, industrial control and street lighting.
The NCS5650 is a high-efficiency, Class AB, low-distortion driver, specifically designed to drive power line mains and capable of accepting a signal from any PLC modem.
It contains an operational amplifier, which can be configured as a unity gain follower buffer, or alternatively used to provide the first stage of a four-pole low-pass filter.
The output stage has the capacity to drive up to 2.0A peak into an isolation transformer or simple coil coupling to the mains.
At an output current of 1.5A, the output voltage is guaranteed to swing within 1.0V or less on either rail, ensuring optimal signal-to-noise (SNR) in harsh environments.
The NCS5650 draws 150uA while in shutdown mode.
Power supply options are single-sided 6V to 12V and dual-balanced +/- 3.0V to +/- 6.0V.
With its full power bandwidth, the NCS5650 can operate in any region of the world while complying with local PLC frequency band regulations such as CENELEC.
The devices have an extended junction temperature range of -40C to +125C.
They are offered in a compact QFN package with an exposed thermal pad for enhanced heat dissipation and increased thermal reliability.
The NCS5650 is offered in a compact 20-pin, 4 x 4 x 1 mm, Pb-free, QFN package.
