Product details
Overview
TLV3012AIDBVRG4 from Texas Instruments is a low-power, push-pull output 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 from 1.65 V to 5.5 V supply. It delivers fail-safe inputs, power-on-reset, and built-in hysteresis for robust sensing in battery-constrained systems such as toll tags and asset trackers.
For engineers reviewing the TLV3012AIDBVRG4 datasheet, TLV3012AIDBVRG4 pinout, TLV3012AIDBVRG4 application, or TLV3012AIDBVRG4 equivalent, this page provides verified functional specifications, package mapping to SOT-23-6, thermal performance data, and real-world use context for low-voltage, high-reliability comparator selection.
Technical Context
The TLV3012AIDBVRG4 implements a rail-to-rail input stage with 200 mV beyond-rail common-mode range and a precision internal series voltage reference (1.242 V ±0.25% initial accuracy, 40–100 ppm/°C drift). Its push-pull output drives logic directly without external pull-up, supporting fast switching (≤4 μs) into 10 pF loads.
As a "B" version device, it integrates power-on-reset (1.9 ms tON), fail-safe inputs that remain valid during undervoltage, and 2–8 mV hysteresis-enabling reliable threshold detection in noisy, low-supply environments like automotive cluster displays and battery management systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct operation from single-cell Li-ion (2.7–4.2 V), coin cell (1.8–3.0 V), or 3.3/5 V rails without regulation. |
| Quiescent Current | 3.1 μA max at 25°C - supports >10-year battery life in always-on asset tracking nodes drawing <10 μA average. |
| Propagation Delay | 2–4 μs (tPLH/tPHL) - ensures timely response to fast-changing sensor signals in lane departure warning systems. |
| Reference Accuracy | ±0.25% initial, ±1.5% over temperature - eliminates need for external trimming in cost-sensitive toll tag voltage monitoring. |
| 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 battery current measurement. |
| Hysteresis | 2–8 mV - suppresses chatter on slow-moving analog inputs like thermistor outputs in industrial temperature monitors. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial edge-sensing applications. |
Pinout & Package
TLV3012AIDBVRG4 is packaged in a 6-pin SOT-23 (DBV) case measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts in portable electronics and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Comparator output | Push-pull digital output capable of sourcing/sinking 5 mA - drives CMOS logic or small LEDs directly without external components. |
| 2 - V− | Negative supply | Ground or negative rail connection; all input/output voltages referenced to this node. |
| 3 - IN+ | Non-inverting input | High-impedance (1013 Ω) input accepting signals up to 0.2 V beyond V+ - enables direct connection to resistive divider networks. |
| 4 - IN− | Inverting input | Identical impedance and voltage range as IN+; used for threshold comparison against reference or sensor signal. |
| 5 - REF | Reference output | Stable 1.242 V source with ≤100 ppm/°C drift and 0.5 mA drive - powers external sensors or sets precise comparator thresholds. |
| 6 - V+ | Positive supply | Main power input; supplies both comparator core and reference circuitry - decoupling capacitor required near this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.242 V reference | Eliminates external reference IC or resistor divider, reducing BOM count and layout area in compact toll tag designs. |
| Fail-safe inputs | Guarantees defined output state during brownout or startup - prevents spurious activation in battery management system fault detection. |
| Power-on-reset (POR) | Ensures clean output initialization within 1.9 ms of power application - critical for deterministic behavior in automotive cluster wake-up circuits. |
| Built-in hysteresis | Reduces sensitivity to noise-induced switching without external positive feedback resistors - simplifies design of asset tracker low-battery alerts. |
| Push-pull output | Drives high/low actively - avoids pull-up resistor power loss and timing uncertainty in always-on IoT sensor nodes. |
Applications
| Lane Departure Warning | Cluster Display |
|---|---|
Use Scenario: Detecting vehicle drift across lane markings using analog camera or radar signal thresholds. IC Role / Device Role / Timing Role: Comparator comparing sensor output to reference voltage to generate digital alert flag. Use Value: 2–4 μs response time enables real-time reaction; 1.65 V minimum supply supports integration into low-power ADAS domain controllers. | Use Scenario: Monitoring battery voltage or backlight enable status in automotive instrument clusters.

IC Role / Device Role / Timing Role: Low-power comparator generating interrupt to microcontroller upon voltage drop. Use Value: Push-pull output directly interfaces with MCU GPIO; hysteresis prevents repeated wake-ups due to load transients. |
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, identical electrical specs; G4 suffix denotes tape-and-reel packaging per TI standard - no functional difference. | No application impact; both support same operating conditions and pinout. | Select TLV3012BIDBVR if standard TI packaging (non-G4) is preferred for procurement or legacy BOM alignment. |
| MAX9062ASA+ | Higher quiescent current (12 μA), no integrated reference, requires external 1.25 V source; 70 ns propagation delay. | Suitable only where speed outweighs power; not drop-in due to missing reference and different pinout. | Choose MAX9062ASA+ only when sub-100 ns response is mandatory and board space allows external reference. |
Compared with TLV3012AIDBVRG4, TLV3012BIDBVR offers identical functionality in standard packaging, while MAX9062ASA+ trades ultra-low power and integrated reference for higher speed and external reference flexibility - making TLV3012AIDBVRG4 optimal for space- and energy-constrained sensing nodes.

FAQ
What is the reference voltage accuracy of TLV3012AIDBVRG4 over temperature?
The TLV3012AIDBVRG4 features a 1.242 V integrated reference with ±0.25% initial accuracy at 25°C and ±1.5% total accuracy over the full −40°C to +125°C operating range. This specification is confirmed in Section 6.9 of the SBOS300C datasheet and enables stable threshold setting without calibration in automotive and industrial applications.
Does TLV3012AIDBVRG4 require an external pull-up resistor on its output?
No, TLV3012AIDBVRG4 does not require an external pull-up resistor because it uses a push-pull output stage. Unlike open-drain comparators (e.g., TLV3011 variants), the TLV3012AIDBVRG4 actively drives both high and low states - confirmed by its VOH/VOL specifications (90–200 mV from rails at 5 mA) in Section 6.9 of the datasheet.
What is the minimum supply voltage for TLV3012AIDBVRG4?
The TLV3012AIDBVRG4 operates down to 1.65 V, as specified in the "B" version Recommended Operating Conditions (Section 6.6) and Electrical Characteristics (Section 6.9). This enables compatibility with single alkaline cells (1.5 V nominal) and low-voltage LiFePO₄ batteries, distinguishing it from non-"B" versions that require ≥1.8 V.
How does the built-in hysteresis of TLV3012AIDBVRG4 improve noise immunity?
The TLV3012AIDBVRG4 provides 2–8 mV of internal hysteresis (Section 6.9), creating separate upper and lower switching thresholds. This prevents rapid output toggling caused by input noise near the decision point - particularly valuable in asset tracking units where battery voltage measurements may exhibit ripple or EMI coupling.
Is TLV3012AIDBVRG4 pin-compatible with TLV3011AIDBVRG4?
No, TLV3012AIDBVRG4 is not pin-compatible with TLV3011AIDBVRG4 despite sharing the same package and pinout numbering. The TLV3011 variant has an open-drain output requiring a pull-up, while TLV3012AIDBVRG4 uses push-pull - resulting in different output behavior and incompatible drive requirements in existing designs.
