原标题：Freescale SB0410液压和气动阀门控制方案

　　freescale公司的MC34SB0410是4通道阀门和泵控制器片上系统(SoC), 包含4个经过调节的低边驱动器和1个用于控制DC电机的高边驱动器,非常适合用于驱动不带“智能电子装置”的液压或气动阀门.本文介绍了SB0410主要特性,框图,5.0V应用框图,工业型液压和气动控制单元简化框图以及阀门控制器评估板KITVALVECNtleVM主要特性和电路图.

　　The SB0410 device is a SMARTMOS valve and motor controller system designed for use in harsh industrial environments.

　　It has four high-current low-side drivers for use with solenoid valves, and high-side gate pre-driver to control a DC motor through an inexpensive external N-channel MOSFETs. Alongside this, the SB0410 has three analog to digital converters, plus two low-side driver allowing to drive resistive charges. The digital I/O pins can be configured for both 5.0 V and 3.3 V levels for easy connection to any microprocessor. The SB0410 uses standard SPI protocol communication.

　　The SB0410 is a perfect solution for hydraulic and pneumatic applications.

　　阀门控制器评估板KITVALVECNTLEVM

　　The KITVALVECNTLEVM Evaluation Board facilitates the development of hydraulic and pneumatic systems that use either the SB0800 Octal Valves Controller SoC or the SB0410 Quad Valves Controller SoC. The EVB allows designers to evaluate the MC34SB0800 and the MC34SB0410 separately or in unison. Designers monitor and control, through the MCU, the Valve Controller SoC functions using a downloadable Windows-based Graphical User Interface (GUI.) The KITVALVECNTLEVM communicates with the PC through an on-board FTDI to USB port. The board comes preloaded with firmware, but users can download their own firmware using a program connector provided on the board. (Use the S12 Multilink Programmer/Debugger to perform the programming.) The board also contains an SPI connector that allows direct access to the MC34SB0800 and MC34SB0410 SPI pins.
