TLV1824QDRQ1

Comparators Overview

The TLV1824QDRQ1 is an automotive-grade analog comparator featuring four channels in a 14-pin SOIC package. It operates on a supply voltage range of 2.4 V to 40 V with a quiescent current of 5 μA per channel. The device utilizes rail-to-rail inputs and provides open-drain outputs capable of pulling up to 40 V independent of the supply voltage. Key electrical specifications include a typical propagation delay of 420 ns, an input offset voltage of 3 mV, and a power supply rejection ratio of 100 dB.

Comparators Feature Summary

• Qualified for automotive applications meeting AEC-Q100 standards
• Features open-drain output stage allowing pull-up to 40 V independent of supply
• Includes internal Power-On Reset (POR) circuitry for known start-up states
• Supports rail-to-rail input voltage ranges across the full supply spectrum

Comparators Applications

• HEV/EV and power train systems
• Infotainment and cluster modules
• Body control module circuits

Comparators Procurement Notes

Verify the specific ordering suffix 'DRQ1' corresponds to the SOIC-14 package variant. Confirm that the open-drain output configuration aligns with system logic requirements, as this differs from push-pull alternatives. Ensure design documentation accounts for the absence of shutdown functionality inherent to this component family.

Comparators Selection Notes

Select this component when high-voltage tolerance up to 40 V is required alongside low power consumption. The open-drain output necessitates an external pull-up resistor; verify the resistor value meets rise-time and leakage current constraints. Consider the TLV1814QDRQ1 if active sourcing capability is preferred over open-drain sinking.

Comparators Part Context

This part belongs to the TLV18xx-Q1 family of micro-power comparators designed for automotive environments. It shares core architectural features with the TLV181x-Q1 series but distinguishes itself through its open-drain output topology. The device is optimized for applications requiring robust operation across wide temperature ranges and varying supply conditions.

Comparators Replacement Considerations

TLV1814QDRQ1 offers identical electrical performance but utilizes a push-pull output stage instead of open-drain.
