LNBH24

Dual LNB supply and control IC with step-up and I²C interface

Features

■ Complete interface between LNBS and I²C bus

■ Built-in DC-DC converter for single 12 V supply

operation and high efficiency (typ. 93%@0.5 A)

■ Selectable output current limit through external

resistor

■ Compliant with main satellite receivers output

voltage specification

■ New accurate built-in 22 kHz tone generator

meets 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

N-MOS allow low power losses

■ Two output pins suitable for bypassing the

output R-L filter and avoiding 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

Description

Intended for analog and digital DUAL Satellite

receivers/Sat-TV, sat-PC cards, the LNBH24 is a

monolithic voltage regulator and interface IC,

assembled in PowerSSO-36 ePad, specifically

designed to provide the 13/18 V power supply and

the 22 kHz tone signalling for two independent

LNB down-converters in the antenna dishes

and/or multi-switch box. In this application field, it

offers a dual tuner STBs with extremely low

component count, low power dissipation together

with simple design and I2C standard interfacing.
