Comparators datasheet and documents for TLV1821LQDBVRQ1
Comparators Overview
The TLV1821LQDBVRQ1 is an automotive-grade, single-channel analog comparator from the TLV182x-Q1 family. It features a wide supply voltage range of 2.4V to 40V and operates within an ambient temperature range of -40°C to +125°C. The device utilizes rail-to-rail inputs and provides an open-drain output capable of being pulled up to 40V independent of the supply voltage. Key electrical characteristics include a quiescent current of 7µA, an input offset voltage of 500µV, and a typical propagation delay of 420ns at 100mV overdrive.
Comparators Feature Summary
- Qualified for automotive applications with AEC-Q100 Grade 1 certification
- Features an open-drain output stage allowing pull-up voltages up to 40V
- Includes internal Power-On Reset (POR) circuitry for known start-up states
- Supports rail-to-rail input voltage ranges extending beyond supply rails
Comparators Applications
- HEV/EV and power train systems
- Infotainment and cluster modules
- Body control module circuits
Comparators Procurement Notes
Verify the specific 'L' suffix indicates the alternate pinout configuration compatible with legacy devices like LMC7211. Confirm the DBVR package designation corresponds to the SOT-23-5 form factor. Ensure the Q1 suffix matches the required automotive qualification standards for the target application environment.
Comparators Selection Notes
Select this component when an open-drain output is required for logic level translation or wired-OR configurations in high-voltage environments. The wide 40V supply capability distinguishes it from standard low-voltage comparators. Consider the alternate pinout if replacing older LMC72xx series parts without board redesign.
Comparators Part Context
This part belongs to the TLV181x-Q1 and TLV182x-Q1 family of micro-power comparators. While the TLV181x series offers push-pull outputs, the TLV182x series specifically provides open-drain options. The 'L' variant denotes a specific pinout arrangement designed to facilitate upgrades from previous generation Texas Instruments comparator families.
