Texas Instruments TLV3012AIDCKR

Overview

TLV3012AIDCKR from Texas Instruments is a low-power, push-pull output comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (B-version), 2–4 μs propagation delay, and operation from 1.65 V to 5.5 V supply. It features fail-safe inputs, power-on-reset, and built-in hysteresis - enabling reliable threshold detection in battery-constrained systems like toll tags and asset trackers.

For engineers reviewing the TLV3012AIDCKR datasheet, TLV3012AIDCKR pinout, TLV3012AIDCKR application, or TLV3012AIDCKR equivalent, key selection considerations include its SC-70-6 package footprint, integrated reference accuracy (±0.25% initial), input common-mode range extending 200 mV beyond rails, and guaranteed hysteresis (2–8 mV) across –40°C to +125°C.

Technical Context

The TLV3012AIDCKR implements a rail-to-rail input comparator core paired with a precision series voltage reference, both monolithically integrated. Its push-pull output stage delivers defined logic-high and logic-low states without external pull-up, simplifying interface design in microcontroller-based sensing nodes.

As a "B" variant, it includes dedicated POR circuitry that ensures known output state during power ramp-up, fail-safe input protection that prevents erroneous outputs when inputs exceed supply rails, and fixed internal hysteresis to suppress noise-induced oscillation - all while maintaining ultra-low IQ across full temperature and supply range.

FAQ

What is the reference voltage accuracy specification for TLV3012AIDCKR?

The TLV3012AIDCKR features a factory-trimmed 1.242 V series reference with ±0.25% initial accuracy at 25°C and ±1.5% over temperature (–40°C to +125°C). This tight tolerance enables precise threshold setting without external calibration, directly supporting applications such as battery end-of-life detection and regulated power-good signaling in the TLV3012AIDCKR.

Does TLV3012AIDCKR support operation below 1.8 V supply?

Yes - the TLV3012AIDCKR is rated for operation from 1.65 V to 5.5 V, unlike the non-B versions (TLV3012) which require minimum 1.8 V. This lower limit allows direct interfacing with partially discharged single-cell Li-ion batteries (down to ~1.65 V) while maintaining full functionality including reference stability and hysteresis, as confirmed in the TLV3012AIDCKR datasheet Section 6.6.

How does the built-in hysteresis function in TLV3012AIDCKR?

The TLV3012AIDCKR incorporates fixed internal hysteresis of 2–8 mV (typical 6 mV), implemented via internal feedback that shifts the effective trip point after output transition. This eliminates external resistor networks, reduces sensitivity to noise on analog inputs, and ensures clean switching in applications like overvoltage detection - a feature exclusive to the "B" version and explicitly verified in TLV3012AIDCKR's Electrical Characteristics table (Section 6.9).

What is the meaning of "fail-safe inputs" in TLV3012AIDCKR?

Fail-safe inputs in the TLV3012AIDCKR allow IN+ and IN– pins to tolerate voltages from –0.5 V to 7 V independent of supply rails (V+ and V–), preventing damage or undefined behavior during overvoltage, reverse-bias, or hot-swap events. This capability is documented in Absolute Maximum Ratings (Section 6.2) and enables robust interfacing with unregulated sensors or legacy analog sources without external clamping diodes - a key differentiator of the TLV3012AIDCKR.

Can TLV3012AIDCKR drive a 10 kΩ load directly from its REF pin?

Yes - the TLV3012AIDCKR REF pin can source or sink up to 0.5 mA while maintaining reference voltage accuracy within ±1 mV (load regulation ≤1 mV/mA). Driving a 10 kΩ load at 1.242 V draws only 124 µA, well within spec; however, output voltage will drop slightly (≤0.124 mV) due to sourcing load regulation - a value confirmed in Section 6.9's dVOUT/dILOAD parameter for the TLV3012AIDCKR.
