產(chǎn)品介紹 A8292 Features and Benefits
▪ 2-wire serial I2C™ -compatible interface: control (write) and status (read) ▪ LNB voltages (16 programmable levels) compatible with all common standards ▪ Tracking switch-mode power converter for lowest dissipation ▪ Integrated converter switches and current sensing ▪ Provides up to 500 mA per channel and 750 mA total ▪ Static current limit circuit allows full current at startup and 13→18 V output transition; reliably starts wide load range ▪ Push-pull output stage minimizes 13→18 V and 18→13 V output transition times for highly capacitive loads ▪ Adjustable rise/fall time via external timing capacitor ▪ Built-in tone oscillator, factory-trimmed to 22 kHz facilitates DiSEqC™ tone encoding, even at no-load ▪ Four methods of 22 kHz tone generation, via I2C™ data bits and/or external pin ▪ 22 kHz tone detector facilitates DiSEqC™ 2.0 decoding ▪ Auxiliary modulation input ▪ LNB overcurrent with timer ▪ Diagnostics for output voltage level, input supply UVLO, and DiSEqC™ tone output ▪ Cable disconnect diagnostic |
