uln2003a

The ULN2003A is a high-voltage, high-current Darlington transistor array. It consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. Each pair is capable of a maximum load rating of 500mA and a maximum voltage rating of 50V. The ULN2003A is commonly used in applications such as driving unipolar stepper motors, relays, and other high-current/high-voltage loads. It is ideal for interfacing between low-level logic signals and driving higher loads, making it suitable for use in a wide range of industrial and consumer electronics applications. With its high-voltage and high-current capabilities, along with built-in protection diodes, the ULN2003A is a versatile and reliable solution for driving a variety of loads. Its compact and efficient design makes it a popular choice for designers looking for a cost-effective and space-saving solution for their driving needs.
