Applications
TLV7042QDGKRQ1 is designed for automotive body control modules, battery management systems, and in-vehicle power supply monitoring where AEC-Q100 reliability is required. Its dual open-drain comparators are ideal for over-voltage and under-voltage detection on multi-cell battery packs and power rails in EVs and hybrid vehicles. The ultra-low 2-nA bias current also makes it suitable for high-impedance voltage divider sensing networks where quiescent current budget is tight.

Frequently Asked Questions
What qualification standard does TLV7042QDGKRQ1 meet, and what temperature range is it rated for?
TLV7042QDGKRQ1 is AEC-Q100 qualified, the industry standard for automotive integrated circuits, and is rated to operate from -40 degrees C to 125 degrees C. This wide temperature range and automotive qualification make it suitable for under-hood and body-control module designs that experience extreme thermal cycling over the vehicle lifetime.
How does the open-drain output of TLV7042QDGKRQ1 benefit a battery over-voltage protection circuit?
The open-drain output of TLV7042QDGKRQ1 allows multiple comparators or fault signals to be wired directly together on a shared alert line pulled up to the logic supply. In a battery management system monitoring 4 cells, all 4 over-voltage flags can share a single GPIO interrupt pin on the MCU, and the 2-nA input bias current minimizes error on high-impedance resistive dividers used to scale cell voltages down to the reference level.
What is the input offset voltage specification of TLV7042QDGKRQ1, and how does it affect threshold accuracy?
The maximum input offset voltage is 8000 µV, equivalent to 8 mV. For a comparator monitoring a 3.3 V power rail with a 10 kohm to 1 kohm resistive divider, this 8 mV offset translates to a threshold error of approximately 88 mV referred back to the monitored rail, which engineers must include in their worst-case over-voltage window budget for the automotive power supply.
Can TLV7042QDGKRQ1 replace a dual comparator in an existing 8-pin SOIC automotive design?
TLV7042QDGKRQ1 is housed in an 8-pin VSSOP package, which has a smaller footprint than a standard 8-pin SOIC. While pin functions are generally compatible with common dual comparator pinouts, the package change requires a PCB layout revision. However, the AEC-Q100 grade and 2-nA bias current make it a strong upgrade candidate in new designs where a smaller 8-pin package is acceptable.
