TLV6703QDSERQ1

Comparators Overview

The TLV6703QDSERQ1 is an automotive-grade, single-channel micropower comparator with a wide supply voltage range of 1.8 V to 18 V. It features a high-accuracy internal reference threshold of 400 mV, maintaining 1% accuracy over the operating temperature range of -40°C to +125°C. The device includes built-in hysteresis for noise immunity and utilizes an open-drain output capable of sinking up to 40 mA, which can be pulled up to 18 V independent of the supply voltage. It operates with a typical quiescent current of 5.5 µA and is housed in a leadless WSON-6 package.

Comparators Feature Summary

• Qualified for automotive applications under AEC-Q100 standards
• High-precision voltage detection with integrated 400-mV reference
• Built-in hysteresis for stable operation against input glitches
• Open-drain output rated to 18 V independent of supply voltage

Comparators Applications

• Emergency call (eCall) systems
• Automotive head units
• Instrument clusters
• On-board chargers and wireless chargers

Comparators Procurement Notes

Verify the specific ordering suffix QDSERQ1 matches the required WSON-6 package and tape-and-reel quantity. Confirm that the component meets the AEC-Q100 Grade 1 requirements for your target ambient temperature range. Ensure design compatibility with the specified ESD protection levels before finalizing procurement specifications.

Comparators Selection Notes

Select this component when precise voltage monitoring is required within a wide supply range. The fixed 400-mV rising threshold simplifies external resistor divider calculations. The open-drain output allows flexible interfacing with various logic voltage levels via pull-up resistors. Consider the low quiescent current for battery-powered or energy-efficient automotive subsystems.

Comparators Part Context

This part belongs to the TLV67xx family of high-voltage comparators from Texas Instruments. It shares the same core architecture as the non-automotive TLV6703 but includes extended qualification for automotive environments. The device provides a compact solution for precision sensing tasks where power consumption and voltage tolerance are critical constraints.

Comparators Replacement Considerations

The TLV6703 serves as the commercial equivalent. For window comparator functionality, consider the TLV6700 series. Higher voltage ratings up to 36 V are available in the TLV671x series.
