ULQ2003AQDRQ1 Description

Short technical summary and product information.

The ULQ2003AQDRQ1 from Texas Instruments is a high-voltage, high-current Darlington transistor array designed for driving inductive loads. Each of the seven NPN Darlington pairs includes common-cathode clamp diodes, providing essential protection.

 

This device offers a 50V switching voltage and a peak output current of 500mA per channel, with a typical delay time of 1000ns. It is compatible with CMOS and TTL logic inputs and features a 2.7kΩ series base resistor for direct operation with TTL or 5V CMOS devices. The output configuration is low-side, and the input type is inverting.

 

Packaged in a 16-SOIC surface-mount package, the ULQ2003AQDRQ1 operates within a temperature range of -40°C to 105°C (TA). Its design makes it suitable for applications such as relay drivers and solenoid drivers.

 

Qualified for automotive applications, this array provides ESD protection exceeding 200V using the machine model. The Darlington pairs can be paralleled for increased current capability when needed.
