The high-reliability Gimbal Control Electronics System controls the motion of two

or more motors, such as used in solar array actuators and antenna gimbals.

FEATURES

• Use pulsed discretes to turn on active side

• Spacecraft Interface via dual redundant Mil-STD-1553B buses

• Uses +5 V and ±15 V DC/DC Converters with separate EMI Filter

• Motor drive has micro-stepping capabilities

• Motor uses half Bridge driver and QuadPower Mosfet to drive the motor

• Provides 8 Iset power points for each motor

• Provides Encoder LED bias current selectable 20 mA or 35 mA

• Provides SOH Monitoring circuit, 12 bit ADC (internal  voltages and motor current)

• Provides 1 mA constant current for PRTs and Thermistors (8)
