Seven Darlington array
Datasheet - production data
Description
The ULN2001, ULN2002, ULN2003 and ULN 2004 are high voltage, high current Darlington arrays each containing seven open collector Darlington pairs with common emitters. Each channel rated at 500 mA and can withstand peak currents of 600 mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.

ULN2003原理
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。

ULN2003输入电压=5V,适用于TTL COMS,由达林顿管组成驱动电路。
通常单片机驱动ULN2003时,上拉2K的电阻较为合适,同时,COM引脚应该悬空或接电源。

uln2004a原理
**ULN2004A原理如下**:
ULN2004A是一种达林顿晶体管阵列,由七个晶体管组成一个达林顿管,其输出电阻非常低,适合驱动继电器,工作温度范围为-40℃至+125℃。
它内部包含有七个独立的恒流电路,每个可以驱动25V/2.5A的继电器。
每个单独的达林顿管都集成了一个大功率晶体三极管,使得每个输出级可以输出更大的电流,因此可以直接驱动一些简单的开关或者控制电路。
其工作原理主要是通过接受控制器的信号,然后控制输出继电器的开关状态。
当控制信号到来时,会进入反相器,然后反相器的输出则控制驱动器,而驱动器则会打开或关闭连接的继电器。
ULN2004A可以将微弱的信号增强到足够的电压来闭合或断开器件。
因此,它常用于复杂的电路中控制开关或通断电路。
对于用户来说,其具体的应用场景主要取决于系统的需要以及设备本身的能力。
如果需要控制大电流的场合,需要选择适合的大功率型芯片。
如果需要扩展输出的驱动电流或电压的能力,可能需要使用到其他的外部元件。
在设计PCB时,需要考虑到电源噪声的问题,可能需要添加去耦电容等。
以上内容仅供参考,建议查阅厂家提供的技术手册或咨询相关专家,以获取更全面和准确的信息。

DESCRIPTION
The ULN2001A, ULN2002A, ULN2003 and ULN2004A are high voltage, high current darlington arrays each containing seven open collector darlington pairs with common emitters. Each channel rated at 500mA and can withstand peak currents of 600mA. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout.
