The ULN2003ADR is a high-voltage, high-current Darlington transistor array integrated circuit (IC) commonly used for driving inductive loads such as relays, stepper motors, and solenoids. Manufactured by Texas Instruments and other semiconductor companies, it typically contains seven Darlington transistor pairs, each capable of handling loads with up to 500mA of current and 50V of voltage. The ULN2003ADR simplifies interfacing between low-voltage control signals from microcontrollers or logic circuits and higher-voltage loads, providing isolation and protection for the controlling circuitry. This IC is widely used in various applications where reliable and efficient control of inductive loads is required, such as automotive electronics, industrial automation, and robotics.
