A8296SESTR-T Description

Short technical summary and product information.

The Allegro Microsystems A8296SESTR-T is a monolithic linear and switching voltage regulator designed for analog and digital satellite receivers. It provides power and interface signals to an LNB down converter via coaxial cable, requiring few external components.

Key features include integrated boost MOSFET, current sensing, and compensation. It supplies up to 500 mA continuously with an adjustable LNB output current limit ranging from 300 to 500 mA. The device supports 8 programmable LNB output voltage levels and includes an LNB overcurrent limiter with a shutdown timer. A tracking boost converter minimizes power dissipation, and LNB transition times are configurable.

For DiSEqC communications, a tone control pin gates an internally-generated 22 kHz tone. The regulator includes extensive protection features such as UVLO, OCP, TSD, and CPOK. It communicates via a 2-wire bidirectional serial interface compatible with the I2C standard, operating up to 400 kHz.

The A8296SESTR-T is supplied in a 16-lead QFN/MLP (3x3) package, surface mounted, and operates within a temperature range of -20°C to 85°C.
