TLV3231QDCKRQ1

Comparators Overview

The TLV3231QDCKRQ1 is an AEC-Q100 qualified single-channel analog comparator designed for automotive applications. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes 200 µA per channel. The device features a propagation delay of 20 ns, an input offset voltage of ±4 mV maximum, and internal hysteresis of 1.55 mV. It utilizes a push-pull output stage and includes a power-on reset circuit. The component is housed in a SC-70 (DCK) package with five pins.

Comparators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for temperature grade 1
• Integrated power-on reset circuit ensures known startup conditions
• Push-pull output stage capable of sourcing and sinking milliamps of current
• Input voltage range extends 300mV beyond either supply rail

Comparators Applications

• Telematics eCall systems
• Automotive head units
• Instrument clusters
• On-board chargers and wireless chargers

Comparators Procurement Notes

Verify the specific ordering suffix 'Q1' confirms automotive qualification status. Confirm the 'DCK' suffix corresponds to the SC-70-5 package variant. Ensure the datasheet revision matches the design requirements. Validate that the operating temperature range aligns with system specifications.

Comparators Selection Notes

Select this component when high-speed response is required alongside low power consumption. The push-pull output eliminates the need for external pull-up resistors. Verify input signal levels remain within the extended common-mode voltage range. Consider the internal hysteresis value for noise immunity requirements.

Comparators Part Context

This part belongs to the TLV323x-Q1 family of high-speed comparators. It shares functional characteristics with other members like the TLV3232-Q1 but differs in channel count and package options. The family targets automotive environments requiring robust performance under varying thermal conditions.

Comparators Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify that any substitute maintains the same AEC-Q100 qualification level. Ensure the replacement supports the required 20ns propagation delay and 200µA supply current.
