ULQ2003ADR Description

Short technical summary and product information.

The ULQ2003ADR from Texas Instruments is a high-voltage, high-current Darlington transistor array designed for automotive applications. Each device contains seven npn Darlington pairs, each equipped with common-cathode clamp diodes for effective switching of inductive loads. The collector current rating for a single Darlington pair is 500mA.

This array is designed for direct operation with TTL or 5V CMOS devices, featuring a 2.7kΩ series base resistor for each pair. The switching voltage is rated up to 50V, with a peak output current of 0.5A per channel. The operating temperature range is from -40°C to 125°C.

Available in TSSOP, SOIC, and SOT-23 packages, the ULQ2003ADR is qualified for automotive applications and includes ESD protection exceeding 200V. Its high-voltage outputs and input compatibility make it suitable for relay-driver applications and other switching tasks requiring robust performance.

Key electrical characteristics include a typical delay time of 1000ns, a typical voltage at the lowest specified current of 900mV, and a typical output current off of 100µA. The device is designed to handle demanding switching requirements in automotive environments.
