LX7720, Motor Driver

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

LX7720 Features

* Four half-bridge N-channel MOSFET drivers

* Four floating differential current sensors

* Pulse modulated resolver/LVDT transformer driver

* Three differential resolver/LVDT sense inputs

* Six threshold adjustable bi-level logic inputs for Hall effect sensor/
