Texas Instruments TLV3012BIDCKR

Overview

TLV3012BIDCKR from Texas Instruments is a push-pull output, low-power comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current, 2–4 μs propagation delay (low-to-high/high-to-low), and operation down to 1.65 V supply - used in battery-critical systems like toll tags and asset tracking.

For engineers reviewing the TLV3012BIDCKR datasheet, TLV3012BIDCKR pinout, TLV3012BIDCKR application, or TLV3012BIDCKR equivalent, this page delivers verified electrical specs, SC-70 package details, fail-safe input behavior, power-on-reset timing, and real-world comparator selection guidance for ultra-low-power sensing designs.

Technical Context

The TLV3012BIDCKR implements a rail-to-rail input comparator core with built-in hysteresis (2–8 mV), fail-safe inputs that prevent undefined output during power ramp-up, and a dedicated reference output (REF) pin delivering 1.242 V ±0.25% initial accuracy with 40–100 ppm/°C drift.

Its push-pull output drives logic directly without external pull-up, supports 5 mA sink/source, and operates across –40°C to +125°C with input common-mode range extending 200 mV beyond rails - enabling direct interface with sensors and ADC references in single-supply industrial and automotive subsystems.

FAQ

What is the reference voltage accuracy of TLV3012BIDCKR over temperature?

The TLV3012BIDCKR provides a 1.242 V 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. Its drift is bounded at 40–100 ppm/°C, making it suitable for precision threshold detection without calibration in most applications.

Does TLV3012BIDCKR require an external pull-up resistor on the output?

No. TLV3012BIDCKR features a push-pull output stage, so it actively drives both HIGH and LOW states without needing an external pull-up resistor - unlike open-drain comparators such as TLV3011B. This simplifies BOM and improves rise/fall time consistency.

How does the power-on-reset (POR) function in TLV3012BIDCKR?

The TLV3012BIDCKR includes an internal POR circuit that holds the output in a known HIGH state until the supply voltage (V+ − V−) rises above ~1.65 V and stabilizes. This prevents undefined output during power ramp-up - critical for systems where spurious interrupts must be avoided at startup.

Can TLV3012BIDCKR operate from a 1.8 V supply?

Yes. TLV3012BIDCKR is fully specified for operation from 1.65 V to 5.5 V. At 1.8 V, it maintains 3.1 μA max quiescent current, 2–4 μs propagation delay, and functional hysteresis - enabling compatibility with modern ultra-low-voltage microcontrollers and energy-harvesting systems.

What is the maximum load current the REF pin can source or sink?

The REF pin of TLV3012BIDCKR can source or sink up to 0.5 mA while maintaining reference accuracy within specification. Load regulation is 0.36–1 mV/mA when sourcing and 6.6 mV/mA when sinking - values confirmed in Section 6.9 Electrical Characteristics.
