Texas Instruments TLV9024DR

Overview

TLV9024DR from Texas Instruments is a quad-channel precision comparator with open-drain outputs, rail-to-rail fault-tolerant inputs (–0.2 V to 5.7 V), 300 µV max input offset voltage, and 100 ns typical propagation delay at 5 V supply. It operates from 1.65 V to 5.5 V and supports industrial temperature range (–40°C to +125°C), enabling use in motor drive voltage monitoring and factory automation threshold detection.

For engineers reviewing the TLV9024DR datasheet, TLV9024DR pinout, TLV9024DR application, or TLV9024DR equivalent, key selection factors include its open-drain output architecture for flexible level-shifting, ultra-low 16 µA per-channel quiescent current, 5 pA input bias current, and fault-tolerant input capability up to 6 V beyond V–.

Technical Context

The TLV9024DR implements a high-speed, low-power comparator core with internal ESD clamps and snapback protection on inputs, allowing safe operation when inputs exceed V+ or fall below V– by up to 0.3 V. Its open-drain output stage requires an external pull-up resistor and supports sinking up to 100 mA while maintaining <125 mV VOL at 4 mA load.

Designed for precision voltage monitoring in noisy environments, the device features 70 dB CMRR at 5 V supply and 95 dB PSRR for open-drain variants, with input common-mode range extending 0.2 V beyond both rails - critical for detecting overvoltage/undervoltage events in battery-powered or multi-rail systems.

FAQ

What is the maximum input voltage the TLV9024DR can tolerate without damage?

The TLV9024DR inputs are fault-tolerant up to –0.3 V below V– and up to 6 V above V–, regardless of V+ supply level. This allows direct connection to signals like 12 V battery lines or 5 V logic buses without external protection components. The specification is validated across the full –40°C to +125°C temperature range and applies to all four input pairs in TLV9024DR.

Does TLV9024DR support operation from a 1.8 V supply?

Yes, TLV9024DR is fully specified for operation from 1.65 V to 5.5 V, including 1.8 V. At 1.8 V, it maintains 100 ns propagation delay (high-to-low), ±0.3 mV typical input offset, and 16 µA per-channel quiescent current. Input common-mode range extends from (V–) – 0.2 V to (V+) + 0.2 V, ensuring reliable operation even with tight supply margins.

Can TLV9024DR outputs be wire-OR'd together?

Yes - all four outputs of TLV9024DR are open-drain, enabling direct wired-OR connection to a shared pull-up resistor. This configuration is commonly used to aggregate multiple fault signals (e.g., overvoltage, overtemperature, overcurrent) into a single system interrupt line. No additional logic or diodes are required, preserving signal integrity and minimizing board space.

What is the recommended pull-up voltage for TLV9024DR outputs?

TLV9024DR outputs support pull-up voltages up to 6 V, independent of V+. This allows interfacing with higher-voltage logic families (e.g., 3.3 V or 5 V MCU GPIOs) while powered from a lower supply like 1.8 V. The output leakage current remains ≤100 pA at 25°C, ensuring minimal power loss and compatibility with high-value pull-ups (e.g., 100 kΩ) in battery-sensitive applications.

How does TLV9024DR handle input overdrive conditions?

TLV9024DR maintains output phase stability under severe input overdrive: when either input exceeds the opposite rail by ≥100 mV, propagation delay remains tightly controlled at 100 ns (high-to-low) with no output oscillation or latch-up. This behavior is guaranteed across –40°C to +125°C and supports robust operation in noisy motor control or switching power supply feedback paths.
