Description

Features
  • Integrated Circuit DesignFeatures_ULQ2003AQDRQ1

    The ULQ2003AQDRQ1 is an integrated circuit optimized for high-performance switching applications, specifically tailored for automotive environments. It features a 1:1 input-to-output ratio with seven low-side Darlington outputs, each capable of handling a maximum current output of 500mA. This configuration is ideal for driving various loads in automotive systems where reliability and efficiency are crucial.

    High Current Gain and Low Input Current

    This IC utilizes Darlington-connected NPN transistors, providing a very high current gain (β2) that can reach up to 10,000 A/A under specific conditions. This high gain allows this model to deliver significant current to loads while requiring minimal input current. It efficiently converts input signals to the base current through resistors connected to the driver Darlington transistors, ensuring compatibility with low GPIO voltages commonly found in automotive electronics.

    Integrated Protection for Reliable Operation

    This product ensures reliable operation in automotive settings with integrated protection features. Diodes between the output and COM pins suppress voltage spikes from inductive loads, safeguarding the IC against damage when NPN drivers switch off. Reversed-biased diodes on base and collector pins prevent unintended current draw from internal parasitic NPN transistors, ensuring stable performance and signal integrity.
