Texas Instruments TLV3011AIDCKRG4

Overview

TLV3011AIDCKRG4 from Texas Instruments is a low-power, open-drain output comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (B-version), input common-mode range extending 200 mV beyond rails, and operation from 1.65 V to 5.5 V. It serves as a precision threshold detector in battery-constrained systems such as toll tags and asset trackers.

For engineers reviewing the TLV3011AIDCKRG4 datasheet, TLV3011AIDCKRG4 pinout, TLV3011AIDCKRG4 application, or TLV3011AIDCKRG4 equivalent, key selection criteria include its guaranteed 4 μs max propagation delay (low-to-high), ±0.25% reference accuracy, fail-safe inputs, power-on-reset functionality, and SC-70-6 package compatibility for space-constrained PCB layouts.

Technical Context

The TLV3011AIDCKRG4 implements a rail-to-rail input comparator core paired with a buffered, low-drift series voltage reference. Its internal hysteresis (2–8 mV) and POR circuit eliminate external components required for stable startup and noise immunity in low-voltage sensing paths.

Designed for single-supply operation, it supports true beyond-the-rails input operation (–0.2 V to V+ + 0.2 V) and delivers open-drain output compatible with mixed-voltage logic interfaces. The reference output provides up to 0.5 mA sourcing/sinking capability with ≤100 ppm/°C drift over –40°C to +125°C.

Key Specifications

FAQ

What is the reference voltage accuracy of TLV3011AIDCKRG4 over temperature?

The TLV3011AIDCKRG4 reference voltage is specified at 1.242 V with ±0.25% initial accuracy and ≤100 ppm/°C temperature drift over –40°C to +125°C. This yields a maximum total reference error of ±1.5 mV across the full operating range, enabling reliable threshold setting without external trimming.

Does TLV3011AIDCKRG4 require external hysteresis components?

No. TLV3011AIDCKRG4 includes built-in hysteresis of 2–8 mV, eliminating the need for external feedback resistors. This simplifies design, reduces PCB area, and ensures consistent noise immunity across temperature and supply voltage variations - a key advantage over basic comparators like LM393.

Can TLV3011AIDCKRG4 operate from a single 1.8 V supply?

Yes. TLV3011AIDCKRG4 operates from 1.65 V to 5.5 V, making it fully functional at 1.8 V. At this supply, it maintains 3.1 μA max quiescent current, 4 μs max propagation delay, and full reference accuracy - ideal for energy-harvesting or single-cell battery systems.

What is the maximum output sink current of TLV3011AIDCKRG4's open-drain OUT pin?

The TLV3011AIDCKRG4 open-drain output can sink up to 5 mA while maintaining VOL ≤ 200 mV at V+ = 5 V and TA = –40°C to +125°C. This supports direct interface with standard logic-level pull-up resistors (e.g., 10 kΩ to 3.3 V) and drives moderate capacitive loads without buffering.

How does the power-on-reset (POR) function in TLV3011AIDCKRG4 improve system reliability?

The POR circuit in TLV3011AIDCKRG4 holds the output in a known state (high-impedance for open-drain) until the internal reference and comparator bias networks stabilize. This prevents spurious output transitions during power ramp-up - critical in safety-critical applications like automotive cluster alerts or battery cutoff signals.
