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 (PLC) 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-Limit, together with a current limit flag. The device provides two independant 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 (4x4x1 mm3) with an exposed thermal pad for enhanced thermal reliability.
Features
 
  • Rail-to-rail : drop of only +/-1 V with Iout = 1.5A
  • VBB supply voltage 6-12 V
  • Flexible 4th-order filtering
  • Current-limit set with one resistor
  • Diagnostic flags level shitfted to VCC to simplify interface with external MCU - thermal warning flag with flexible threshold setting - thermal error flag and hutdown - overcurrent flag
  • Enable/shutdown control
  • Extended junction temperature range : -40 °C to +125 °C
  • Small package : 20-pin 4x4x1 mm3 NQFP with exposed thermal pad
  • Optimized for operation in the Cenelec A to D frequency band
  • This is a Pb-free device
Applications
  • Smart and renewable energy controls
  • Solar panel control
  • Smart street lighting control
  • In-home display for split metering
  • Home and building automation
  • Transmission of alerts (fire, gas leak, water leak)
  • Electricity metering
  • Industrial control
