Product details
Overview
TLV3012BIDBVR 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. 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 TLV3012BIDBVR datasheet, TLV3012BIDBVR pinout, TLV3012BIDBVR application, or TLV3012BIDBVR equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in automotive and industrial sensing, and two confirmed alternative comparators with documented functional trade-offs.
Technical Context
The TLV3012BIDBVR integrates a precision 1.242 V series reference with ±0.25% initial accuracy and ≤100 ppm/°C drift, stable under 10 nF capacitive load and capable of sourcing/sinking up to 0.5 mA. Its comparator core supports rail-to-rail input common-mode range (–0.2 V to V+ + 0.2 V) and delivers fast, deterministic switching via push-pull output with 10 ns rise/fall times (CL = 10 pF).
Power-on-reset ensures known output state at power-up; fail-safe inputs prevent undefined behavior during undervoltage conditions; and built-in hysteresis (2–8 mV, temperature-dependent) eliminates oscillation near threshold. All functions operate across –40°C to +125°C with supply voltage as low as 1.65 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct integration into single-cell Li-ion (2.5–4.2 V), coin-cell (1.8–3.0 V), and 3.3/5 V systems without LDO. |
| Quiescent Current | 3.1 μA max (TA = 25°C) - extends battery life in always-on monitoring nodes beyond 10 years on CR2032. |
| Reference Voltage | 1.242 V ±0.25% - provides stable, factory-trimmed threshold for precision window or overvoltage detection without external components. |
| Propagation Delay | 2–4 μs (TPD-LH/HL, CL = 10 pF) - supports response to fast transients in motor fault detection or battery cell balancing. |
| Input Common-Mode Range | –0.2 V to V+ + 0.2 V - allows direct sensing of signals below ground (e.g., shunt current monitoring) or above supply rail. |
| Hysteresis | 2–8 mV (TA = –40°C to +125°C) - suppresses noise-induced chatter on slow-moving analog inputs like thermistor outputs. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor drives, and outdoor IoT deployments. |
Pinout & Package
SOT-23-6 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant. Thermal resistance RθJA = 162.5°C/W (DBV), suitable for high-density PCB layouts with minimal copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Comparator output | Push-pull active-high/active-low drive - eliminates need for external pull-up resistor; sinks/source up to 5 mA. |
| 2 - V– | Negative supply | Ground or negative rail reference - all input/output 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 DACs without loading; CM range extends 200 mV beyond rails. |
| 4 - IN– | Inverting input | High-impedance (10¹³ Ω) node - used for reference comparison; fail-safe logic holds output high if IN– floats or drops below V– – 0.3 V. |
| 5 - REF | Reference output | Stable 1.242 V source - supplies bias to external circuitry (e.g., ADC reference, sensor excitation); load-regulated to ±1 mV/mA. |
| 6 - V+ | Positive supply | Main power rail - supplies both comparator core and reference; PSRR ≥100 μV/V ensures immunity to supply ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe inputs | Guarantees high output when IN– falls below V– – 0.3 V - prevents false triggering during power ramp-up or sensor disconnect. |
| Power-on-reset (POR) | Asserts defined output state within 1.9 ms of V+ crossing 1.65 V - eliminates boot-time glitches in safety-critical latches. |
| Built-in hysteresis | 2–8 mV internal threshold offset - removes need for external positive feedback resistors in noisy environments (e.g., motor control feedback). |
| Integrated 1.242 V reference | ±0.25% initial accuracy, ≤100 ppm/°C drift - replaces discrete reference ICs and reduces BOM count in space-constrained designs. |
| Ultra-low IQ | 3.1 μA max at 25°C - enables continuous monitoring in energy-harvesting systems where average power budget is <10 μW. |
Applications
| Lane Departure Warning | Asset Tracking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012IDBVR | No POR, no fail-safe inputs, no hysteresis, 5 μA max IQ, min supply 1.8 V | Requires external hysteresis and POR circuitry; less robust in undervoltage or noisy conditions | Choose when lowest cost is critical and system already implements reset supervision and noise filtering. |
| TLV7012DBVR | Lower IQ (350 nA), no integrated reference, open-drain output, 1.6 V min supply | Needs external reference and pull-up; better for ultra-low-power sleep modes but adds design complexity | Prefer when >10-year battery life is mandatory and board space allows external reference + resistor network. |
Compared with TLV3012IDBVR, TLV3012BIDBVR adds critical reliability features (POR, fail-safe, hysteresis) at modest IQ increase; versus TLV7012DBVR, it trades ultra-low IQ for integrated reference and push-pull drive-reducing BOM and layout risk in mid-power sensing nodes.

FAQ
What is the minimum supply voltage required for TLV3012BIDBVR to operate correctly?
The TLV3012BIDBVR operates down to 1.65 V, as specified in its Recommended Operating Conditions table. At this voltage, the internal voltage reference remains stable at 1.242 V ±0.25%, and the comparator maintains full functionality including power-on-reset and fail-safe inputs. Operation below 1.65 V may result in undefined output states or reference instability.
Does TLV3012BIDBVR require external hysteresis components?
No, TLV3012BIDBVR includes built-in hysteresis of 2–8 mV across –40°C to +125°C, eliminating the need for external positive feedback resistors. This internal hysteresis is factory-trimmed and temperature-compensated, providing consistent noise immunity without additional passive components or layout area.
How does the power-on-reset (POR) function behave in TLV3012BIDBVR?
The TLV3012BIDBVR asserts a defined output state (high for push-pull configuration) within 1.9 ms after V+ crosses 1.65 V. This POR circuit ensures predictable startup behavior independent of input conditions, preventing spurious transitions during power ramp-up-critical for latch-based safety circuits and microcontroller wake-up signaling.
Can the REF pin of TLV3012BIDBVR supply current to external circuitry?
Yes, the REF pin delivers a stable 1.242 V output capable of sourcing or sinking up to 0.5 mA while maintaining ±1 mV/mA load regulation. It is commonly used to bias sensor bridges, set ADC reference points, or drive low-current logic thresholds-replacing discrete reference ICs and reducing total solution size.
Is TLV3012BIDBVR pin-compatible with TLV3012IDBVR?
Yes, TLV3012BIDBVR and TLV3012IDBVR share identical SOT-23-6 (DBV) pinout and footprint. However, the "B" version adds POR, fail-safe inputs, and hysteresis-functions that are not present in the non-B variant. No PCB changes are required for drop-in replacement, but system-level validation of timing and startup behavior is recommended.
