STMicroelectronics LNBP13SP-TR

The STMicroelectronics LNBP13SP-TR is a highly integrated voltage regulator and interface IC designed for analog and digital satellite receiver systems. It serves as a complete solution for controlling and powering low-noise block converters (LNBs) in satellite applications, ensuring stable operation and efficient power delivery. This device supports two LNBs with selectable supply and standby modes, making it ideal for set-top boxes and satellite receivers that require flexible and reliable LNB management. The built-in 22 kHz tone oscillator, precisely factory-trimmed, enables seamless DiSEqC™ signal transmission for satellite communication control, while its fast oscillator start-up enhances performance and command accuracy.

The LNBP13SP-TR incorporates multiple protection and diagnostic features to ensure safe and consistent operation. It includes short-circuit and over-temperature protection, backward current protection, and a cable length compensation function to maintain optimal signal and power quality across different installation environments. Two separate supply inputs allow for efficient power management and reduced heat dissipation, while the auxiliary modulation input extends functionality for customized system designs. Packaged in a 10-lead PowerSO format, this IC offers robust electrical performance in a compact footprint, making it suitable for modern satellite receiver architectures.
