onsemi motor driver ULN2003ADR2G Darlington transistor array, relay driver IC Chip Detailed Overview
The ULN2003ADR2G from onsemi is a high-voltage, high-current Darlington transistor array designed for driving inductive loads such as relays, solenoids, stepper motors, and LED displays. It integrates seven NPN Darlington pairs with common emitters, each capable of handling 500mA continuous current and 50V output voltage, making it ideal for interfacing low-power logic circuits with high-power peripherals. The device includes integrated suppression diodes for inductive load protection, ensuring reliable operation in switching applications.
Housed in a 16-pin SOIC package, the ULN2003ADR2G offers a compact and thermally efficient solution for space-constrained designs. It operates with a wide input voltage range (3V to 15V), compatible with TTL, CMOS, and PMOS logic levels, simplifying integration with microcontrollers and digital ICs. The low power consumption and high noise immunity enhance system stability in industrial and automotive environments.
The ULN2003ADR2G is widely used in industrial automation, automotive systems, and consumer electronics, where robust load-driving capabilities are required. Its high current gain and low saturation voltage minimize power dissipation, improving overall efficiency. The device is rated for -20°C to +85°C operation, ensuring reliable performance in moderate environmental conditions.
