  • Intended for analog and digital satellite receivers/sat-TV, sat-PC cards, the LNBH23 is a monolithic voltage regulator and interface IC, assembled in PowerSSO-24 ePAD and QFN32 (5 x 5 mm.) ePAD, specifically designed to provide the 13/18 V power supply and the 22 kHz tone signalling to the LNB down-converter in the antenna dish or to the multi-switch box. In this application field, it offers a complete solution with extremely low component count, low power dissipation together with simple design and I²C standard interfacing.

    主要特性

    • Complete interface between LNB and I²C bus
    • 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 bi-directional 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 level diagnostic feedback by I²C bits
    • LNB short circuit dynamic protection
    • ± 4 kV ESD tolerant on output power pins
