Texas Instruments TLV3012AIDCKRG4

Overview

TLV3012AIDCKRG4 from Texas Instruments is a push-pull output, low-power comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (–40°C to +125°C), 2–4 μs propagation delay (low-to-high/high-to-low), and rail-to-rail input common-mode range extending 200 mV beyond supply rails. It operates from 1.65 V to 5.5 V and is used in battery management systems for precise voltage threshold detection.

For engineers reviewing the TLV3012AIDCKRG4 datasheet, TLV3012AIDCKRG4 pinout, TLV3012AIDCKRG4 application, or TLV3012AIDCKRG4 equivalent, key selection criteria include its integrated reference accuracy (±0.25% initial), built-in hysteresis (2–8 mV), fail-safe inputs, power-on-reset functionality, and SC-70-6 package compatibility with space-constrained portable electronics designs.

Technical Context

The TLV3012AIDCKRG4 implements a precision comparator core with an on-chip series voltage reference buffered to drive up to 0.5 mA load. Its internal hysteresis eliminates oscillation near threshold crossings without external components, while fail-safe inputs ensure defined output states during undervoltage or floating-input conditions.

Power-on-reset asserts a known output state during supply ramp-up, and the push-pull output delivers rail-swing capability (VOL ≤ 200 mV at 5 mA sink, VOH ≤ 200 mV at 5 mA source) without requiring external pull-up resistors-enabling direct interface with CMOS logic and microcontroller GPIOs.

FAQ

What is the reference voltage accuracy of TLV3012AIDCKRG4 over temperature?

The TLV3012AIDCKRG4 reference voltage has ±0.25% initial accuracy at 25°C and maintains ±1.5% total accuracy over –40°C to +125°C, with a maximum temperature coefficient of 100 ppm/°C. This ensures stable thresholding in automotive and industrial environments where ambient temperature varies widely, and the 1.242 V reference remains usable for precision voltage monitoring without recalibration.

Does TLV3012AIDCKRG4 require external hysteresis components?

No, TLV3012AIDCKRG4 includes built-in hysteresis of 2–8 mV depending on supply voltage and temperature, eliminating the need for external positive-feedback resistors. This simplifies PCB layout, reduces BOM count, and guarantees consistent noise immunity across operating conditions-critical in battery-powered systems where board space and component count are tightly constrained.

Can TLV3012AIDCKRG4 operate from a 1.65 V supply?

Yes, TLV3012AIDCKRG4 is fully specified to operate from 1.65 V to 5.5 V, making it compatible with single-cell lithium batteries (nominal 3.0–3.7 V) and even partially discharged cells down to ~1.7 V. Its 3.1 μA max quiescent current at 1.65 V enables multi-year operation in always-on monitoring applications such as smart tags and remote sensors.

What is the purpose of the REF pin on TLV3012AIDCKRG4?

The REF pin on TLV3012AIDCKRG4 provides a buffered 1.242 V output capable of sourcing or sinking up to 0.5 mA. It can serve as a stable reference for external ADCs, other comparators, or bias networks-reducing system-level component count and improving overall measurement accuracy by avoiding resistor-divider drift and tolerance stacking.

How does the fail-safe input feature work in TLV3012AIDCKRG4?

The fail-safe input feature in TLV3012AIDCKRG4 ensures the output defaults to a known logic state (high for TLV3012x) when either IN+ or IN– is disconnected, shorted to V–, or driven below (V–) – 0.3 V. This prevents undefined behavior in fault conditions-such as broken sensor wiring or connector disengagement-making TLV3012AIDCKRG4 suitable for automotive and industrial safety-monitoring functions.
