Texas Instruments TLV3011BIDCKR

Overview

TLV3011BIDCKR from Texas Instruments is a low-power, open-drain output comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current, ±0.25% reference accuracy, and built-in hysteresis - designed for battery-critical applications such as toll tags and asset tracking where supply voltage may drop to 1.65 V.

For engineers reviewing the TLV3011BIDCKR datasheet, TLV3011BIDCKR pinout, TLV3011BIDCKR application, or TLV3011BIDCKR equivalent, key selection factors include its fail-safe inputs, power-on-reset functionality, 2–4 μs propagation delay (low-to-high/high-to-low), rail-to-rail input range extending 200 mV beyond rails, and SC-70-6 package compatibility with space-constrained PCB layouts.

Technical Context

The TLV3011BIDCKR implements a precision comparator core with an on-chip series voltage reference buffered to drive up to 0.5 mA load while maintaining ≤100 ppm/°C drift. Its internal hysteresis (2–8 mV) eliminates oscillation near threshold without external components.

Fail-safe inputs ensure defined output states during power ramp-up or undervoltage conditions, and power-on-reset guarantees a known initial output state independent of input voltage timing - critical for deterministic system boot in automotive and industrial sensors.

FAQ

What is the reference voltage accuracy of TLV3011BIDCKR over temperature?

The TLV3011BIDCKR features a 1.242 V integrated reference with ±0.25% initial accuracy at 25°C and ±1.5% total accuracy over –40°C to +125°C, as specified in Section 6.9 of the datasheet. This tight tolerance eliminates need for post-assembly calibration in most battery-monitoring designs.

Does TLV3011BIDCKR require external hysteresis components?

No - TLV3011BIDCKR includes factory-trimmed internal hysteresis of 2–8 mV, fully characterized over temperature and supply voltage. This removes the need for external feedback resistors, saving PCB area and eliminating drift-related inaccuracies common with discrete networks.

Can TLV3011BIDCKR operate from a 1.65 V supply?

Yes - TLV3011BIDCKR is explicitly rated for operation down to 1.65 V (Section 6.6), unlike the standard TLV3011 which requires ≥1.8 V. This enables direct use with aging primary cells or low-dropout battery configurations without intermediate regulation.

What is the function of the REF pin on TLV3011BIDCKR?

The REF pin delivers the internally generated 1.242 V reference voltage, capable of sourcing/sinking up to 0.5 mA while maintaining ±100 ppm/°C drift. It can serve as a precision threshold for other comparators, ADC reference, or bias source - all without loading the main comparator's decision path.

How does the fail-safe input feature work in TLV3011BIDCKR?

TLV3011BIDCKR's fail-safe inputs guarantee a defined output state (high-impedance for open-drain OUT) even when either IN+ or IN– is floating, shorted, or driven beyond the supply rails - preventing undefined logic states during power-up, cable disconnect, or ESD events per Section 9.4 of the datasheet.
