Product details
Overview
TLV3012AIDBVT from Texas Instruments is a push-pull output, low-power comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (at 25°C), 2–4 μs propagation delay, and operation from 1.65 V to 5.5 V supply. It features fail-safe inputs, power-on-reset, built-in hysteresis, and rail-to-rail input common-mode range extending 200 mV beyond rails - used in battery management systems and toll tag sensing circuits.
For engineers reviewing the TLV3012AIDBVT datasheet, TLV3012AIDBVT pinout, TLV3012AIDBVT application, or TLV3012AIDBVT equivalent, this page delivers verified electrical specs, package mapping to SOT-23-6 (DBV), functional role in threshold detection with internal reference, and validated alternative options for low-voltage, space-constrained comparator designs.
Technical Context
The TLV3012AIDBVT implements a precision comparator core with an on-chip series voltage reference buffered to drive external circuitry up to 0.5 mA. Its architecture integrates hysteresis (2–8 mV) and power-on-reset to ensure deterministic startup behavior without external components.
It supports single-supply operation down to 1.65 V with rail-to-rail input capability and push-pull output capable of sourcing/sinking ≥5 mA while maintaining <200 mV swing from rails at full load - enabling direct interface with logic families including 1.8 V and 3.3 V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables use in ultra-low-voltage battery-powered systems (e.g., coin-cell or LiFePO₄) without level-shifting. |
| Quiescent Current | 3.1 μA max at 25°C - supports multi-year operation in always-on asset tracking or wake-up monitoring applications. |
| Reference Voltage | 1.242 V ±0.25% initial accuracy - provides stable, factory-trimmed threshold for precise overvoltage/undervoltage detection. |
| Propagation Delay | 2–4 μs (low-to-high & high-to-low) - suitable for fast-response safety-critical comparisons such as battery cell balancing triggers. |
| Input Common-Mode Range | (V−) − 0.2 V to (V+) + 0.2 V - allows direct sensing of signals below ground or above supply, e.g., shunt-based current monitoring. |
| Hysteresis | 2–8 mV - suppresses chatter in noisy environments like automotive cluster displays or toll transponder RF front-ends. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial BMS, and outdoor tolling infrastructure deployments. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Comparator output | Push-pull active driver; sinks or sources current directly to MCU GPIO or LED without external pull-up. |
| 2 - V− | Negative supply | Ground or negative rail reference; all voltages referenced to this node; supports true single-supply operation. |
| 3 - IN+ | Non-inverting input | High-impedance (10¹³ Ω) node; accepts signals from sensors, dividers, or reference outputs with minimal loading. |
| 4 - IN− | Inverting input | Same impedance as IN+; differential pair enables configurable threshold comparison with hysteresis. |
| 5 - REF | Reference output | Stable 1.242 V source; supplies external circuitry (e.g., ADC reference, sensor bias) with ≤100 ppm/°C drift. |
| 6 - V+ | Positive supply | Main power input; decoupling capacitor required near pin to maintain reference stability and switching integrity. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012BIDBVR | Same silicon, tape-and-reel packaging (3,000 pcs/reel); identical electrical specs and pinout. | No functional difference; suited for high-volume automated assembly where reel format is required. | Select TLV3012BIDBVR for SMT production lines requiring standard 7″ reels and moisture-sensitive device handling per J-STD-020. |
| TLV7012DRYR | Lower quiescent current (350 nA), no integrated reference, open-drain output only, SC-70-6 package. | Requires external reference and pull-up; better for nano-power wake-up but lacks self-contained threshold generation. | Choose TLV7012DRYR only when ultra-low IQ dominates design priority and reference can be shared across multiple comparators. |
Compared with TLV3012AIDBVT, TLV3012BIDBVR offers identical performance in reel format for volume manufacturing, while TLV7012DRYR trades integrated reference and push-pull drive for 10× lower IQ - making TLV3012AIDBVT optimal for space-constrained, self-contained threshold detection where supply >1.65 V is available.
