Inquiry Add To Bom

LNBH23LQTR General Description

Intended for analog and digital satellite receivers, the LNBH23L is a monolithic voltage regulator and interface IC, assembled in QFN32 5 x 5 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.


Key Features

  • Complete interface between LNB 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 by external resistor
  • Compliant with main satellite receivers output voltage specification
  • Auxiliary modulation input (EXTM pin) facilitates DiSEqC? 1.X encoding
  • Accurate built-in 22 kHz tone generator suits widely accepted standards
  • Low-drop post regulator and high efficiency step-up PWM with integrated power NMOS allow low power losses
  • Overload and over-temperature internal protections with I2C diagnostic bits
  • LNB short circuit dynamic protection
  • ± 4 kV ESD tolerant on output power pins
