TLC393QDRG4Q1

Comparators Overview

The TLC393QDRG4Q1 is a dual MicroPWR LinCMOS voltage comparator manufactured by Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 4 V to 16 V and features an open-drain output type. Key electrical parameters include a maximum propagation delay of 4.5 µs, a typical common-mode rejection ratio (CMRR) of 84 dB, and a maximum input offset voltage of 5 mV at 10 V. The device draws a maximum quiescent current of 90 µA and supports a differential input type with a maximum input bias current of 5 pA at 5 V. It is housed in an 8-SOIC package and functions reliably across an operating temperature range of -40°C to +125°C.

Comparators Feature Summary

• Automotive-grade reliability certified under the AEC-Q100 standard for robust performance in vehicle environments.
• LinCMOS technology enables ultra-low power consumption suitable for battery-operated systems.
• Open-drain output configuration allows flexible interfacing with various logic families through external pull-up resistors.

Comparators Applications

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

Comparators Procurement Notes

Verify that the component carries the Q1 suffix to confirm AEC-Q100 automotive qualification status. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements. Confirm RoHS compliance specifications align with regional manufacturing regulations before finalizing procurement orders.

Comparators Selection Notes

Select this comparator when low static current and wide supply voltage operation are required in space-constrained designs. The open-drain output necessitates an external pull-up resistor, which must be sized appropriately for the desired switching speed and load conditions. Consider the 4.5 µs propagation delay for timing-sensitive applications.

Comparators Part Context

This part belongs to the TLC393 family of dual comparators from Texas Instruments. It shares functional similarities with the non-automotive TLC393QDR but includes specific qualification for automotive use. The device utilizes LinCMOS technology to achieve low power consumption while maintaining adequate performance for general-purpose comparison tasks.

Comparators Replacement Considerations

The TLC393QDR serves as a non-automotive equivalent. Verify if automotive qualification is strictly required before substituting. Other family members like the LMV393 offer different voltage ranges and should be evaluated based on specific supply constraints.
