TLV6700QDSERQ1

Comparators Overview

The TLV6700QDSERQ1 is an automotive-grade micropower window comparator from Texas Instruments. It operates on a supply voltage range of 1.8 V to 18 V and features two high-accuracy comparators with an internal 400-mV reference. The device provides open-drain outputs rated up to 18 V, capable of sinking 40 mA. It includes built-in hysteresis for noise immunity and meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Comparators Feature Summary

• AEC-Q100 qualified for automotive environments with extended temperature support
• High threshold accuracy with low quiescent current consumption
• Open-drain outputs allow flexible pull-up voltage selection independent of supply
• Integrated hysteresis prevents false triggering from input glitches

Comparators Applications

• Emergency call (eCall) systems
• Automotive head unit monitoring
• Instrument cluster voltage supervision
• On-board charger and wireless charger protection

Comparators Procurement Notes

Verify the specific package variant against the datasheet orderable addendum, as the Q1 suffix denotes automotive qualification while the DSE suffix indicates the WSON-6 package. Confirm that the required operating temperature range aligns with the specified -40°C to +125°C junction limit. Ensure design compatibility with the 1.8 V minimum supply requirement and 18 V output rating before finalizing procurement.

Comparators Selection Notes

Select this component when designing circuits requiring precise window detection for voltages exceeding the supply rail via resistor dividers. The wide input common-mode range allows monitoring signals up to 6.5 V regardless of the VDD level. Consider the low input bias current if utilizing high-value resistors in the divider network to minimize power loss.

Comparators Part Context

This part belongs to the TLV6700-Q1 family of micropower comparators designed specifically for automotive applications. It serves as a robust solution for overvoltage and undervoltage detection in vehicle electronics where reliability and low power consumption are critical constraints.

Comparators Replacement Considerations

The TLV6700-Q1 industrial version shares identical electrical characteristics but lacks automotive qualification. Verify package pinout compatibility when substituting other window comparers within the TLV67xx series.
