NJM45001

NJM45001 Analog Front-End IC for Power Line Communication ■ FEATURES ●Higher Integration ・Power line driver with Thermal protection and current limit and low noise receiver amplifier ●Higher transmit performance ・High output current : 3A(typical) output current provide high transmission power even under lower power line impedance circumstance ・Low distortion (THD ≤ -60dB(typical) ) It gives designer easier design for circuit under all of regulations (Cenerec/ARIB/FCC) ●Flexible receive gain control -18dB/-6dB/0dB/+12dB ●Power supply 8V to 22V (Typical usage 12V/15V) ●Small package HTSSOP24 ■ APPLICATION ●Smart Meter ●Lighting system ●HEMS system ■ GENERAL DESCRIPTION The NJM45001 is an integrated, Powerline commu- nications (PLC) analog front-end (AFE) device that is capable of capacitive- or transformer-coupled connecttions to the powerline while under the control of a Renesas Electronics Corporation Modem IC (e.g. uPD809508K8). The integrated driver is able to drive low-impedance line that require up to 3.0A (typical) into reactive road. The integrated receiver is able to select gain that is -18dB, -6dB, 0dB and +12dB. The NJM45001 operates from a single power supply in the range of 8V to 22V. At maximum output current, a wide range output swing provides an 11-Vpp capability with a nominal 15V supply. The NJM45001 is internally protected against overtemperature conditions. It also provides an adjustable current limit. An interrupt output is provided that indicates therma...
