LNBH23LQTR ST Power Management IC | 32-VFQFN Exposed Pad | 2.5V-5.5V, 800mA

Product Overview

The LNBH23LQTR is a monolithic voltage regulator and interface IC designed for satellite LNB (Low Noise Block) power supply and control. Manufactured by STMicroelectronics, this device integrates a boost converter, linear regulator, and DiSEqC (Digital Satellite Equipment Control) interface in a compact 32-VFQFN package with exposed pad for enhanced thermal performance. It operates from a 2.5V to 5.5V input and delivers a regulated output voltage selectable between 13V and 18V, with a maximum output current of 800mA. The device supports both 22kHz tone and DiSEqC 2.x protocols for LNB switching and control.
