The ULN2003AN is a high-voltage, high-current Darlington transistor array. It consists of seven NPN Darlington pairs that feature high-voltage outputs (up to 50V) and high-current outputs (up to 500mA). Each Darlington pair is also equipped with an internal suppression diode for inductive loads, making it ideal for driving relays, motors, and other high-power devices. The ULN2003AN is designed to provide a simple solution for driving inductive loads with microcontrollers and other low-power control systems. With its versatile and reliable performance, the ULN2003AN is widely used in various applications, including motor control, LED displays, stepper motor drivers, and more. Its compact 16-pin package and low power consumption make it suitable for a wide range of electronic designs. Whether you are designing a new project or replacing existing components, the ULN2003AN offers a cost-effective and efficient solution for driving high-voltage and high-current loads.
