TLV1812QPWRQ1

Comparators Overview

The TLV1812QPWRQ1 is an automotive-grade dual-channel analog comparator from Texas Instruments, housed in an 8-pin TSSOP package. It operates within a supply voltage range of 2.4 V to 40 V and consumes 5 µA per channel. Key electrical specifications include a typical input offset voltage of 3 mV, a maximum input bias current of 0.15 pA, and a typical propagation delay of 420 ns. The device features rail-to-rail inputs and push-pull outputs, with an operating temperature range of -40°C to +125°C.

Comparators Feature Summary

• Qualified for automotive applications with AEC-Q100 Grade 1 certification
• Features rail-to-rail input capability extending beyond supply rails
• Includes internal Power-On Reset (POR) circuitry for known start-up states
• Provides push-pull output stage capable of sourcing and sinking milliamps

Comparators Applications

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

Comparators Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-8 package variant required for your design. Confirm that the Q1 suffix aligns with your automotive qualification requirements. Ensure the component meets RoHS standards for your target market. Cross-reference the datasheet revision date against your manufacturing timeline to ensure documentation currency.

Comparators Selection Notes

Select this component when high-voltage operation up to 40 V is required alongside low quiescent current consumption. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Verify that the 420 ns propagation delay meets your system timing constraints. Consider the thermal performance of the TSSOP package if multiple channels are heavily loaded.

Comparators Part Context

This part belongs to the TLV181x-Q1 family of micro-power comparators. It shares core specifications with single-channel (TLV1811-Q1) and quad-channel (TLV1814-Q1) variants. The primary distinction lies in the number of integrated comparator channels and the corresponding package pin count. All family members share the same 40 V rating and 5 µA per channel power profile.

Comparators Replacement Considerations

Direct functional replacements within the same package include other TLV1812-Q1 variants with different suffixes, such as TLV1812IDRQ1 (SOIC-8). Verify pinout compatibility before substitution. Alternative packages like VSSOP or WSON exist but require layout changes.
