LX7720 Description
The LX7720 is a spacecraft motor driver that is radiationhardened by design and works with either a space FPGA controller such as RTG4, RTAX-S/SL, and RT PolarFire, or a space MCU such as SAMRH71F20, SAMV71Q21RT, and SAM3X8ERT. The LX7720 contains four half-bridge drivers with floating current sense for motor coil driving, six bi-level inputs for sensing Hall effect sensors or rotary encoders, and a resolver or LVDT...
