ULQ2004A is a high-voltage, high-current Darlington transistor array manufactured by Allegro MicroSystems.

The ULQ2004A is a high-voltage, high-current Darlington transistor array manufactured by Allegro MicroSystems. Below are the factual specifications, descriptions, and features from the Manufactor Datasheet:

Specifications:

  • Configuration: Seven NPN Darlington pairs with common emitters.
  • Output Voltage Rating: 50V (max).
  • Output Current Rating: 500mA (per channel, max).
  • Input Voltage Compatibility: 3V to 15V (TTL, CMOS compatible).
  • Clamp Diodes: Integrated for inductive load protection.
  • Package Options: DIP-16, SOIC-16.
  • Operating Temperature Range: -20°C to +85°C.

Descriptions:

  • The ULQ2004A is designed for interfacing low-voltage logic circuits with high-voltage/high-current loads such as relays, solenoids, and lamps.
  • Each of the seven Darlington pairs includes suppression diodes for inductive transient protection.
  • Suitable for automotive, industrial, and consumer applications.

Features:

  • High-Voltage Outputs: Up to 50V.
  • High-Current Drive: 500mA per channel.
  • Logic-Compatible Inputs: Works with 3V to 15V control signals.
  • Integrated Suppression Diodes: Eliminates the need for external diodes when driving inductive loads.
  • Wide Operating Temperature Range: Suitable for harsh environments.
  • Industry-Standard Pinout: Compatible with similar Darlington arrays.

This information is based solely on Allegro's datasheet for the ULQ2004A.
