TLV1824PWR

Comparators Overview

The TLV1824PWR is a quad-channel analog comparator from the Texas Instruments TLV182x family, housed in a TSSOP-14 package. It features rail-to-rail inputs and open-drain outputs capable of pulling up to 40V independent of the supply voltage. The device operates on a wide supply range of 2.4V to 40V with a quiescent current of 5µA per channel. Key electrical parameters include a typical propagation delay of 420ns, an input offset voltage of ±0.5mV, and an input bias current of 150fA. It includes a Power-On Reset (POR) feature and supports operation from -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail input capability extending beyond supply rails for flexible signal interfacing
• Open-drain output stage allowing logic level translation and pull-up to 40V independent of supply
• Integrated Power-On Reset (POR) ensures known output state during power transitions
• Micro-power consumption with 5µA quiescent current per channel across the full voltage range

Comparators Applications

• Appliances
• Factory automation and control
• Motor drives
• Infotainment and cluster systems

Comparators Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-14 package variant when sourcing. Confirm that the open-drain output configuration meets system requirements, as it necessitates an external pull-up resistor for high-level signaling. Ensure the selected pull-up voltage does not exceed the 40V absolute maximum rating for the output pin.

Comparators Selection Notes

Select this component for applications requiring high-voltage tolerance with low power consumption. The open-drain output is suitable for interfacing with different logic families or driving capacitive loads like MOSFET gates via external pull-ups. Consider the 420ns propagation delay for timing-critical paths and verify that the 5µA per channel current draw fits the total budget for multi-channel designs.

Comparators Part Context

The TLV1824PWR belongs to the TLV18xx family of comparators, which offers both push-pull (TLV181x) and open-drain (TLV182x) output options. This family is designed for portable, automotive, and industrial applications due to its wide supply range and micro-power characteristics. The quad-channel version provides four independent comparators in a single compact package.

Comparators Replacement Considerations

The TLV1824DR is a functional equivalent in the SOIC-14 package. For single-channel replacements, consider the TLV1821 series. Verify pinout compatibility if substituting with alternate pinout variants like the TLV1821L.
