TLC393QDRQ1

Comparators Overview

The TLC393QDRQ1 is a dual micro-power LinCMOS voltage comparator designed for automotive applications, holding AEC-Q100 qualification. It operates within a supply voltage range of 4 V to 16 V and draws a typical quiescent current of 40 uA. The device features an open-drain output capable of sourcing 6 mA per channel. Key electrical specifications include a maximum response time of 4.5 us, an input offset voltage (Vos) of 5 mV, and an input bias current (Ib) of 5 pA. It functions reliably across an extended temperature range from -40 C to +125 C and is housed in an SOIC-8 surface-mount package.

Comparators Feature Summary

• Automotive-grade reliability with AEC-Q100 certification for robust performance in vehicle environments.
• Ultra-low power consumption enabled by LinCMOS technology, suitable for battery-operated systems.
• Open-drain output configuration allows flexible interfacing with various logic families and voltage levels.

Comparators Applications

• Automotive sensor signal conditioning
• Battery management system monitoring
• General-purpose voltage threshold detection

Comparators Procurement Notes

Verify the specific suffix QDRQ1 to confirm automotive grade and tape-and-reel packaging. Ensure the design supports the open-drain output requirement with appropriate pull-up components. Confirm that the 4 V minimum supply voltage aligns with the target application's power rails. Check for any recent product change notifications regarding manufacturing site or material composition updates.

Comparators Selection Notes

Select this component when automotive qualification and low static current are primary requirements. The 4.5 us propagation delay may be insufficient for high-speed switching applications; consider faster alternatives if speed is critical. The wide supply voltage range accommodates varying automotive bus conditions. Ensure the PCB layout accounts for the SOIC-8 thermal dissipation characteristics under continuous operation.

Comparators Part Context

This part belongs to the TLC393 family of dual comparators. The 'Q' prefix denotes automotive qualification, while 'RQ1' specifies the reel packaging and automotive grade. It serves as a low-power alternative to standard bipolar comparators in automotive electronics where energy efficiency and reliability are paramount.

Comparators Replacement Considerations

TLC393QDRG4Q1 is a verified equivalent variant within the same family offering identical functional specifications and automotive qualification.
