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.
SB0410主要特性:
•Operating voltage 6.0V to 36V
•Four valves control
•Four current regulated valves up to 2.25 A(5.0 kHz)
•Pump motor pre-driver up to16 kHz PWM
•16-bit SPI interface
•Three 10-bit ADC channels..
