ULQ2003AD Description

Short technical summary and product information.

The ULQ2003AD from Texas Instruments is a high-voltage, high-current Darlington transistor array. Each device consists of seven NPN Darlington pairs, each capable of handling 500mA collector current and featuring high-voltage outputs up to 50V. Common-cathode clamp diodes are integrated for switching inductive loads.

 

This array is designed for direct operation with TTL or 5V CMOS devices, featuring a 2.7kΩ series base resistor for each Darlington pair. The input compatibility includes CMOS and TTL logic levels. The device operates over a temperature range of -40°C to 85°C.

 

Applications for the ULQ2003AD include relay drivers, hammer drivers, lamp drivers, and display drivers. The ULQ2003AD is supplied in a 16-SOIC package, suitable for surface mount applications. Its output configuration is low-side, and it has an inverting input type.

 

Key electrical characteristics include a switching voltage of 50V, peak output current of 0.5A, and an output current per channel of 500mA. The typical delay time is 1000ns, and the voltage at the lowest specified current is 900mV.
