ULQ2003AQDRQ1 TI Power Distribution Switches, Load Drivers

The ULQ2003A-Q1 is an automotive-grade high-voltage high-current darlington transistor array qualified for AEC-Q100 applications, featuring seven NPN darlington pairs. It operates with output voltage up to 50V and each channel can sink up to 500mA continuous current. Integrated suppression diodes are included for inductive load protection. Inputs are compatible with 5V TTL and CMOS logic, with 2.7kΩ input resistors for direct operation from logic supplies. The 'Q1' designation indicates automotive qualification with extended temperature range. Selection is standard for automotive load driving requiring multiple high-current sinking channels. Applications include relay drivers for automotive body control modules (BCMs), stepper motor drivers for HVAC actuators, LED lamp drivers for lighting systems, solenoid drivers, and industrial load switching requiring AEC-Q100 reliability.
