ON Semiconductor introduces the new NCS5650 line driver device, mainly offered for Power Line Carrier (PLC) communications applications such as smart metering, industrial control and street lighting.

The NCS5650 is an efficient, class AB low distortion driver created to drive power line mains. It is capable of accepting signals from any power line carrier modem and has an operational amplifier that can be configured as a unity gain follower buffer. Alternatively, its amplifier may be used to provide the first stage of a 4-pole low pass filter. The output stage has the capacity drive up to 2A peak into an isolation transformer or simple coil coupling to the mains. At an output current of 1.5A, the output voltage is designed to swing within 1V or less on either rail, ensuring optimal signal-to-noise ratio (SNR) even in harsh environments.

The NCS5650 draws just 150 A during shutdown mode. Furthermore, power supply options are single-sided 6V to 12V and dual balanced ?3.0 V to ?6.0 V.

The device can operate in any region of the world with its unique full power bandwidth, while complying with local PLC frequency band regulations like CENELEC.

These devices have an extended junction temperature range of -40 degrees C to +125 degrees C. These drivers come in a compact QFN package with an exposed thermal pad for improved heat dissipation as well as increased thermal reliability, providing a further bill of materials reduction for cost sensitive designers.

The NCS5650 is provided in a compact 20-pin, 4mm x 4mm x 1mm, Pb-free, QFN package. It is currently priced at US$3.73 per unit, for 10,000-unit quantities.
