The ULN2803A from UMW (Youtai Semiconductor) is a high-voltage, high-current Darlington driver IC. It comprises 8 NPN Darlington pairs, each with an open-collector output and a series 2.7KΩ resistor, making it compatible with TTL and 5V CMOS logic levels without requiring a buffer.
This device is capable of sinking up to 500mA of current per channel and has a withstand voltage of 50V. It is suitable for driving high-load currents and provides solutions for various interface applications. The ULN2803A operates over a wide voltage range and includes clamp diodes for switching inductive loads.
Key electrical characteristics include an output voltage up to 50V and an output current up to 500mA per channel. The IC has a typical Vce Saturation of 1.3V at 350mA and 250uA input current. It operates within a temperature range of -40°C to 85°C.
The ULN2803A is available in an 18-SOP (Surface Mount) package, measuring 18-SOIC (0.295", 7.50mm Width). Its applications include relay drivers, clamp drivers, stepper motor drivers, and driving magnet valves or DC brushless motors.
