Description

The ZLPM8010 is a power management and control solution for satellite set-top boxes (STBs). Based on an efficient boost converter the ZLPM8010 provides the power supply of up to 750mAand all the control signals required by a single port satellite Low Noise Block (LNB). The ZLPM8010 includes an accurate 22kHz tone generator to provide DiSEqC™ control words or continuous tone for band switching control. To provide a reliable DiSEqC™ 2.0 solution the IC includes a DiSEqC™ detector with unwanted signal rejection. Controlled by I2C™ or logic inputs and with the minimal external components the ZLPM8010 provides a high performing cost efficient solution.

Features and Benefits

• Efficient boost converter providing an accurate adjustable power supplies LNBs
• Operates from a single rail supply
• Provides a protected output of up to 750mA
• Adjustable current limit for system flexibility
• Designed for stability with low power LNBs
• Provides standard voltage / tone and DiSEqC™ control signals and allows for regional variations.
• Internal 22kHz generator for DiSEqC™ control and traditional band switching
• 22kHz maintains shape across all load conditions
• Internal reliable tone detector for DiSEqC™ 2.0 systems
• Controlled by I2C™ interface or independent logic control
• Built in multiple diagnostics and protection for IC and LNB protection
• Minimal external components for a simple, reliable and cost effective solution

Applications

• Single / Dual Tuner Satellite Set-Top Boxes
• Satellite PC Cards
• TV’s with Integrated Satellite Tuners
• Hybrid Set-Top Boxes
