在自动化密集的的场合会有很多被控元件如继电器,微型电机,风机,电磁阀,空调,水处理等元件及设备,这些设备通常由CPU所集中控制,由于控制系统不能直接驱动被控元件,这需要由功率电路来扩展输出电流以满足被控元件的电流,电压。ULN2XXXX高压大电流达林顿晶体管阵列系列产品就属于这类可控大功率器件,由于这类器件功能强、应用范围语广。因此,许多公司都生产高压大电流达林顿晶体管阵列产品,从而形成了各种系列产品。838电子ULN2003是什么-
原理:LN2003也是一个7路反向器电路,即当输入端为高电平时ULN2003输出端为低电平,当输入端为低电平时ULN2003输出端为高电平,继电器得电吸合。如图九所示
