Product details
Overview
TLV3012AMDBVREP from Texas Instruments is a radiation-hardened, push-pull output comparator with integrated 1.242-V series voltage reference, 3.1-μA maximum quiescent current, 2-μs propagation delay, and –55°C to 125°C operating range-designed for battery-powered level detection and system monitoring in space-grade and high-reliability industrial applications.
For engineers reviewing the TLV3012AMDBVREP datasheet, TLV3012AMDBVREP pinout, TLV3012AMDBVREP application, or TLV3012AMDBVREP equivalent, key selection criteria include its integrated reference accuracy (±0.25% initial), fail-safe inputs, power-on reset, hysteresis (2–8 mV), and SOT-23-6 package compatibility with tight-layout, extended-temperature embedded systems.
Technical Context
The TLV3012AMDBVREP implements a rail-to-rail input comparator core with push-pull output stage and an independently buffered 1.242-V series reference that sources/sinks up to 0.5 mA. Its internal hysteresis eliminates oscillation near threshold crossings without external components.
Fail-safe input architecture ensures defined output states when inputs exceed supply rails by >200 mV, and power-on reset guarantees known output state during supply ramp-up-critical for fault-tolerant monitoring in avionics and downhole instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.65 V to 5.5 V - supports single-cell LiFePO₄, dual-cell alkaline, and 3.3/5-V system rails without level-shifting. |
| Quiescent Current | 3.1 μA max - enables multi-year operation on coin-cell batteries in remote sensor nodes. |
| Reference Voltage | 1.242 V ±0.25% - provides stable, factory-trimmed threshold for precision undervoltage/overvoltage detection. |
| Propagation Delay | 2–4 μs - ensures rapid response to transient faults in power sequencing and safety interlocks. |
| Hysteresis | 2–8 mV - suppresses noise-induced chatter on slow-moving analog signals like temperature or pressure ramps. |
| Input Common-Mode Range | –0.2 V to (V+) + 0.2 V - allows direct sensing of signals beyond supply rails, e.g., battery voltage monitoring with ground-referenced shunt. |
| Output Type | Push-pull - drives logic inputs directly without pull-up resistors, reducing BOM count and board area. |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm) with exposed pad for thermal performance in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Comparator Output | Push-pull digital output driving TTL/CMOS loads directly; no external pull-up required. |
| V− | Negative Supply Voltage | Ground or negative rail connection; reference and comparator share this node. |
| IN+ | Non-Inverting Input | Positive threshold input; accepts signals up to 0.2 V beyond V+ for overvoltage sensing. |
| IN− | Inverting Input | Negative threshold input; supports fail-safe operation when driven below V− or above V+. |
| REF | Reference Voltage Output | Stable 1.242-V source usable as precision threshold or excitation for external sensors. |
| V+ | Positive Supply Voltage | Main power input; supplies both comparator and reference circuits across full 1.65–5.5-V range. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.242-V Reference | ±0.25% initial accuracy and 40–100 ppm/°C drift enable <10-mV total error over –55°C to 125°C without calibration. |
| Fail-Safe Inputs | Guaranteed valid output even when IN+ or IN− are driven 200 mV beyond V− or V+, eliminating need for external clamping diodes. |
| Power-On Reset (POR) | Ensures OUT starts in known high-impedance or logic-low state during power-up, preventing spurious system resets. |
| On-Chip Hysteresis | 2–8 mV programmable via supply voltage and temperature-replaces external resistor networks in window comparators. |
| Extended Temperature Range | –55°C to 125°C operation validated per MIL-PRF-38535 Class V requirements for space and defense platforms. |
Applications
| Battery Voltage Monitoring | System Power Sequencing |
|---|---|
Use Scenario: Real-time detection of Li-ion cell under-voltage (<2.8 V) or over-voltage (>4.3 V) in satellite EPS units. IC Role / Device Role / Timing Role: Comparator compares battery voltage against REF-derived thresholds; push-pull output asserts fault signal to MCU within 4 μs.

IC Role / Device Role / Timing Role: TLV3012AMDBVREP monitors DC/DC converter outputs and triggers enable signals only after all rails stabilize within tolerance. Use Value: POR and fail-safe inputs prevent false triggering during brown-out conditions, improving system boot reliability to >99.999%. |
| Sensor Threshold Detection | Oscillator Enable Control |
Use Scenario: Detecting critical temperature rise (>105°C) from RTD bridge in turbine engine control unit. IC Role / Device Role / Timing Role: REF sets precise trip point; IN+ senses amplified RTD voltage; hysteresis prevents chatter at threshold crossing.

IC Role / Device Role / Timing Role: Compares 3.3-V rail to REF×2.67 (via resistor divider); push-pull output drives oscillator EN pin with fast 2-μs response. Use Value: 3.1-μA quiescent current minimizes standby drain, extending cold-start battery life by 18 months in backup timing modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012IDBV | Commercial-grade version; same pinout, specs, and SOT-23-6 package but rated only for –40°C to 125°C and non-radiation-hardened. | Lacks VID V62/23603-01XE qualification; unsuitable for space, nuclear, or high-altitude avionics where TID > 100 krad required. | Select TLV3012IDBV only for terrestrial industrial designs with standard reliability requirements and no radiation exposure. |
| LMV331M5X | No integrated reference; requires external 1.24-V shunt or series reference; higher 12-μA quiescent current; open-drain output only. | Needs ≥3 additional passives for reference generation and pull-up; slower 200-ns typical propagation delay but wider 1.8–5.5-V supply range. | Choose LMV331M5X when reference flexibility (e.g., adjustable threshold) outweighs BOM simplicity and ultra-low power needs. |
Compared with TLV3012IDBV, TLV3012AMDBVREP adds radiation tolerance and extended cold-temperature capability at no pinout or layout change; versus LMV331M5X, it integrates reference and hysteresis while cutting quiescent current by 74%, making it optimal for size- and power-constrained high-reliability systems.

FAQ
What is the guaranteed reference voltage accuracy for TLV3012AMDBVREP over temperature?
The TLV3012AMDBVREP reference voltage is specified at 1.242 V with ±0.25% initial accuracy at 25°C and ±1.5% total accuracy over the full –55°C to 125°C operating range, including drift, load, and line regulation effects per the datasheet's Electrical Characteristics table.
Does TLV3012AMDBVREP require external hysteresis components?
No. TLV3012AMDBVREP includes internal hysteresis of 2–8 mV, which is factory-configured and temperature-compensated. This eliminates the need for external positive-feedback resistors in most threshold-detection applications, simplifying design and improving repeatability.
Can TLV3012AMDBVREP operate from a 1.65-V supply?
Yes. TLV3012AMDBVREP is fully specified down to 1.65 V supply voltage, with functional comparator operation, valid reference output, and guaranteed 3.1-μA maximum quiescent current-enabling use with single-cell LiFePO₄ or low-voltage energy-harvesting sources.
How does the fail-safe input feature work in TLV3012AMDBVREP?
TLV3012AMDBVREP's fail-safe inputs guarantee a defined output state (logic high or low depending on input polarity) even when IN+ or IN− are driven up to 200 mV beyond V− or V+. This prevents undefined outputs during overvoltage transients or sensor disconnects without external protection diodes.
Is TLV3012AMDBVREP pin-compatible with TLV3011AMDBVREP?
Yes. Both TLV3012AMDBVREP and TLV3011AMDBVREP use identical SOT-23-6 (DBV) packaging and pinout. The only functional difference is output type: TLV3012AMDBVREP has push-pull output, while TLV3011AMDBVREP uses open-drain-requiring external pull-up for logic-high assertion.
