Product details
Overview
TLV3012AIDBVR 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 (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 TLV3012AIDBVR datasheet, TLV3012AIDBVR pinout, TLV3012AIDBVR application, or TLV3012AIDBVR equivalent, this page delivers verified electrical specs, package mapping, functional role in sensing and monitoring circuits, and validated alternative options for low-voltage, high-accuracy comparator designs.
Technical Context
The TLV3012AIDBVR implements a precision comparator core with built-in series voltage reference and push-pull output stage-eliminating external pull-up requirements. Its architecture supports fail-safe inputs, power-on-reset, and integrated 2–8 mV hysteresis, enabling robust operation in noisy environments without external components.
It features dual functionality: the comparator compares signals referenced to its internal 1.242 V source (±0.25% initial accuracy), while the reference output supplies up to 0.5 mA with ≤100 ppm/°C drift and stability under 10 nF capacitive load-making it suitable as a compact, self-contained threshold generator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct use with single-cell Li-ion (2.7–4.2 V), coin cell (1.8–3.0 V), and 3.3 V/5 V systems without level shifting. |
| Quiescent Current | 3.1 μA max at 25°C - supports multi-year battery life in always-on asset tracking and toll tag applications. |
| Propagation Delay | 2–4 μs (low-to-high & high-to-low) - provides fast response for real-time overvoltage/undervoltage detection in BMS. |
| Reference Voltage | 1.242 V ±0.25% (initial), ≤100 ppm/°C drift - delivers stable, factory-trimmed threshold without external resistor dividers. |
| 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., battery cell monitoring. |
| Hysteresis | 2–8 mV (temperature-dependent) - prevents oscillation on slow-moving or noisy inputs without external feedback. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cluster and under-hood industrial sensor interfaces. |
Pinout & Package
SOT-23-6 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Comparator output | Push-pull digital output; drives high/low actively - no external pull-up required; compatible with 1.65 V logic thresholds. |
| 2 - V− | Negative supply rail | Ground or negative reference node; all voltages referenced to this pin; supports true single-supply operation. |
| 3 - IN+ | Non-inverting input | Accepts input signals from (V−) − 0.2 V to (V+) + 0.2 V; high-impedance (10¹³ Ω) minimizes loading on sensor sources. |
| 4 - IN− | Inverting input | Same common-mode range as IN+; differential input pair enables flexible threshold configuration (e.g., IN− = REF, IN+ = sensed voltage). |
| 5 - REF | Reference output | Stable 1.242 V source; supplies up to 0.5 mA; used directly as comparator reference or external analog reference. |
| 6 - V+ | Positive supply rail | Maximum 5.5 V; powers both comparator core and reference; low dropout design ensures regulation down to 1.65 V total supply. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.242 V reference | ±0.25% initial accuracy and ≤100 ppm/°C drift - eliminates external voltage divider and trimming, reducing BOM count and layout area. |
| Fail-safe inputs | Guaranteed defined output state when inputs float or exceed supply rails - prevents undefined logic states in open-sensor fault conditions. |
| Power-on-reset (POR) | Ensures known output state during power ramp-up - critical for reliable startup in battery-powered toll tags and cluster displays. |
| Internal hysteresis | 2–8 mV programmable via supply voltage and temperature - suppresses chatter on marginal thresholds without external resistors. |
| Rail-to-rail input with 200 mV beyond rails | Supports direct connection to battery terminals or shunt monitors without level-shifting circuitry - simplifies high-side sensing. |
Applications
| Lane Departure Warning | Cluster Display Monitoring |
|---|---|

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 | Identical pinout, same SOT-23-6 package, but specified with tighter 1.223–1.260 V reference range and enhanced ESD (±2000 V HBM). | Preferred for new designs requiring higher reference accuracy (±0.25% vs ±1%) and extended ESD robustness in manufacturing. | Select TLV3012BIDBVR if reference tolerance and HBM rating are critical; TLV3012AIDBVR remains valid for cost-sensitive legacy BOMs. |
| MAX9062ASA+ | Higher quiescent current (12 μA), no integrated reference, requires external 1.25 V source; SO-8 package (larger footprint). | Used where higher speed (150 ns) or dual-channel integration is needed, but adds external reference and increases board area. | Choose MAX9062ASA+ only when >10× faster response is required and space/layout constraints allow SO-8; not drop-in compatible. |
Compared with TLV3012BIDBVR, the TLV3012AIDBVR offers lower cost and proven field reliability but trades ±1% reference accuracy and slightly reduced ESD margin; versus MAX9062ASA+, it saves board space and external components at the expense of speed and channel count.

FAQ
What is the reference voltage accuracy of the TLV3012AIDBVR?
The TLV3012AIDBVR features a factory-trimmed 1.242 V series voltage reference with ±1% initial accuracy over temperature (−40°C to +125°C), and typical drift of ≤100 ppm/°C. This specification is confirmed in Section 6.9 of the SBOS300C datasheet under "Voltage Reference" parameters, and applies directly to the TLV3012AIDBVR variant.
Does the TLV3012AIDBVR have built-in hysteresis?
Yes, the TLV3012AIDBVR includes integrated hysteresis of 2–8 mV, which varies with supply voltage and temperature. This feature is explicitly documented in the "Features" section and Electrical Characteristics table (Section 6.9) of the datasheet for the "B" version family, and TLV3012AIDBVR is a member of that family.
Can the TLV3012AIDBVR operate from a 1.8 V supply?
Yes, the TLV3012AIDBVR supports a minimum supply voltage of 1.65 V and is fully specified 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 full functionality of its reference and comparator stages - confirmed in Recommended Operating Conditions (Section 6.6) and Electrical Characteristics (Section 6.9).
What is the output type of the TLV3012AIDBVR?
The TLV3012AIDBVR has a push-pull output stage, meaning it actively drives both high and low states without requiring an external pull-up resistor. This is clearly differentiated from the open-drain TLV3011x variants and is stated in the "Description" section and Pin Functions table of the SBOS300C datasheet.
Is the TLV3012AIDBVR pin-compatible with other devices in the TLV301x family?
Yes, the TLV3012AIDBVR shares the identical SOT-23-6 (DBV) pinout with TLV3011AIDBVR, TLV3012BIDBVR, and TLV3011BIDBVR - confirmed in Figure 5-1 and Table 5-1 of the datasheet. All use the same pin numbering: OUT, V−, IN+, IN−, REF, V+ - enabling direct substitution within the same package variant.
