TLV1812QDGKRQ1

Comparators Overview

The TLV1812QDGKRQ1 is an automotive-grade dual-channel analog comparator from Texas Instruments, housed in a VSSOP-8 package. It operates on a supply voltage range of 2.4V to 40V with a quiescent current of 7µA per channel. The device features rail-to-rail inputs and push-pull outputs, delivering a typical propagation delay of 420ns at 100mV overdrive. It includes a Power-On Reset (POR) circuit for known startup states and meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Comparators Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• Push-pull output stage capable of sourcing and sinking milliamps of current
• Integrated Power-On Reset (POR) ensures defined output states during power transitions
• Rail-to-rail input capability extending beyond the negative supply rail

Comparators Applications

• Hybrid electric vehicle (HEV) and electric vehicle (EV) power trains
• Infotainment systems and instrument clusters
• Body control modules

Comparators Procurement Notes

Verify that the component matches the specific Q1 suffix indicating automotive qualification and DGKRQ1 suffix confirming the VSSOP-8 package type. Confirm the datasheet revision aligns with your design requirements. Ensure ESD handling procedures are followed as the device is sensitive to electrostatic discharge despite internal protection structures.

Comparators Selection Notes

Select this part when high-voltage operation up to 40V is required alongside low power consumption. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Verify that the 420ns propagation delay meets system timing constraints and that the rail-to-rail input range accommodates the signal levels present in the application environment.

Comparators Part Context

This device belongs to the TLV181x-Q1 family of micro-power comparators. It shares core electrical characteristics with single-channel and quad-channel variants within the same series. The primary distinction lies in the number of channels provided; this specific model integrates two independent comparators into a compact eight-pin surface-mount package suitable for space-constrained automotive designs.

Comparators Replacement Considerations

The TLV1822QDGKRQ1 serves as a functional substitute within the same family, offering identical pinout and electrical performance but utilizing an open-drain output configuration instead of push-pull.
