LX7720-DB

The following are key features of the LX7720-DB Daughter Board:

• Supports direct connection to FPGA evaluation boards with an FMC-HPC connector such as RTG4 FPGA DEV-KIT, RT PolarFire FPGA RTPF-DEV-KIT, PolarFire FPGA MPF300-EVAL-KIT, and SmartFusion2 SoC FPGA M2S150-ADV-DEV-KIT
• A 2x20 0.1" pin header provides alternative access to signals for connection to non-FPGA control systems
  
• Linker boards are included to connect to the SAMRH71F20-EK evaluation kit and SAMRH71-TFBGA-EK evaluation kit for the radiation hardened SAMRH71F20 MCU, and the SAMRH707F18-EK evaluation kit for the radiation hardened SAMRH707F18 MCU
• Includes the eight NFETs and output current sensing for the full four half-bridges supported by the LX7720, allowing direct connection to typically 3-phase PMSM and BLDC motors, or 2-phase bipolar stepper motors
• Motor supply can be from the included 24V DC adapter or an external 0V to 60V supply
• On-board regulators generate the 15V VGS gate drive supply and 5V VCC analog supply for the LX7720
• An on-board regulator provides a 3.3V VDD logic supply for typical applications. A different logic supply can be provided from either the FPGA FMC-HPC connector, the 2x20 0.1" pin header, or a 2-pin header if desired
• The LX7720's MOD_CLK clock can be provided by an on-board 27MHz oscillator module, the FPGA FMC-HPC connector, the 2x20 0.1" pin header, or via an SMA connector
• The LX7720's CP_CLK clock is provided externally through the FPGA FMC-HPC connector, the 2x20 0.1" pin header, or via an SMA connector
• A 0.1" pin header provides access to the LX7720's six BLI bi-level comparator inputs. The corresponding six BLO comparator outputs are routed to both the FPGA FMC-HPC connector and the 2x20 0.1" pin header
• The LX7720's resolver/LVDT interface is configured targetting applications using a square drive waveform as used by the available RTG4 demo firmware for driving a BLDC with resolver position feedback
