CIRCUITO INTEGRADO LNBH23PPR

CIRCUITO INTEGRADO  LNBH23PPR

 ■ Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% @ 0.75 A), with integrated NMOS

■ Selectable output current limit by external resistor

■ Compliant with main satellite receiver systems specifications

■ New accurate built-in 22 kHz tone generator suits widely accepted standards (patent pending)

■ Fast oscillator start-up facilitates DiSEqC™ encoding

■ Built-in 22 kHz tone detector supports bidirectional DiSEqC™ 2.0

■ Very low-drop post regulator and high efficiency step-up PWM with integrated power NMOS allow low power losses

■ Two output pins suitable to by-pass the output R-L filter and avoid any tone distortion (R-L filter as per DiSEqC™ 2.0 specs, see typ. application circuits)

■ Overload and over-temperature internal protections with I²C diagnostic bits

■ Output voltage and output current leveldiagnostic feedback by I²C bits

■ LNB short circuit dynamic protection

■ ± 4 kV ESD tolerant on output power pins
