Freescale's new highly integrated valve controller SoCs, the SB0410 and SB0800 offer high precision current measurement, SPI connectivity and sophisticated functional safety management features for hydraulic and pneumatic systems control. The SoCs are single-chip analog controllers engineered to simultaneously manage up to eight valves, regulating current in real-time and running the motor. The devices are suitable for loads with high inrush current and allow driving to high frequency (up to 5 kHz). Target applications include hydraulic and pneumatic systems, oxygen concentrators, medical equipment, 3D printers, drink dispensers, farming and factory equipment as well as water control for irrigation. When connected to a network, the integrated SoCs enable predictive maintenance and diagnostics designed specifically for harsh environments, allowing operators in industrial, medical and agricultural applications to know when maintenance is needed and where. The diagnostic capability also allows the controllers to detect bad connections, high temperatures or other safety concerns, and then shut down automatically. The devices incorporate both motor pump and valve control functionalities, and include self-recovery features.
The SB0410 and the SB0800 are available now for suggested resale prices of $4.65 and $6.90 each/10,000, respectively. Demonstrating the key features of the SoCs through a USB connection, the KITVALVECNTLEVM evaluation board minimizes software development cycles and is also available now for $265.00.
