Linear Chip - ASL622S

It is used in the antenna pointing mechanism to accurately control the antenna pointing; the load mechanism drives the filter wheel switching of the spectrometer, etc.; the control moment gyro controls the high-speed rotating gyro to produce greater control torque; the momentum wheel/reaction flywheel controls the satellite attitude by changing the flywheel speed; the electric servo system controls the engine nozzle swing to achieve thrust vector control; the electric propulsion system controls the ion or Hall thruster for long-term orbit maintenance and maneuvering of the satellite. Provides a complete set of commercial aerospace-grade motor drive series chips such as motor control, pre-drive, MOSFET, etc., adapted to mainstream commercial satellite motors, provides system solution reference design and motor control algorithms, and quickly realizes the design and application of radiation-resistant commercial aerospace-grade motor drive systems.

It is used in commercial aerospace laser communication modules such as EDFA and optical modules, helping commercial aerospace EDFA modules to accurately monitor parameters, real-time signal processing and fast fault response, accurately regulate the power of pump light sources, and have strong anti-irradiation ability in the face of complex radiation environments in space to ensure long-term reliable operation of EDFA. Realize communication and control management and power supply in optical modules, and provide commercial aerospace-grade series chips.

It is used in satellite data management subsystems, measurement and control subsystems, thermal control subsystems, propulsion subsystems, attitude control systems (star sensors, gyroscopes, solar sensors, etc.), execution propulsion systems (electric thrust, reaction flywheels, magnetic torques, etc.), communication payloads, remote sensing payloads, navigation payloads, scientific exploration payloads, etc., providing communication interconnection between key components in satellite platforms and payloads, and providing commercial aerospace-grade series communication interface chips.

Used in nuclear power plant intelligent robots, intelligent inspection equipment, circulating water systems, three waste treatment systems, chemical and volume control systems, equipment cooling water systems, ventilation and air conditioning systems, radioactive waste treatment systems, etc. Provides MCU main controller, DCDC and LDO power chips, communication interfaces and other anti-total dose series chips.
