ULQ2003ATDRQ1 Description

Short technical summary and product information.

The ULQ2003ATDRQ1 from Texas Instruments is a high-voltage, high-current Darlington transistor array designed for automotive applications. Each device contains seven npn Darlington pairs, each rated for a 50V switching voltage and 500mA peak output current. The outputs are equipped with common-cathode clamp diodes, making them suitable for switching inductive loads.

 

This array features a 2.7kΩ series base resistor for each Darlington pair, enabling direct operation with TTL or 5V CMOS devices. The typical delay time is 1000ns, and the input is compatible with CMOS and TTL logic levels. The operating temperature range is from -40°C to 125°C.

 

The ULQ2003ATDRQ1 is available in multiple package options including TSSOP (16 pins, 32 mm²), SOIC (16 pins, 59.4 mm²), and SOT-23-THN (16 pins, 8.4 mm²). Its design includes ESD protection exceeding 200V (machine model) and high-voltage outputs up to 50V.

 

This component is qualified for automotive applications and is well-suited for relay-driver applications and other high-power switching tasks where robust performance and high voltage handling are required.
