Product details
Overview
TLV3011AMDBVREP from Texas Instruments is an enhanced-product, radiation-tolerant, low-power open-drain comparator with integrated 1.242-V series voltage reference, 3.1-μA maximum quiescent current, –55°C to 125°C operating temperature range, and rail-to-rail input common-mode range extending 200 mV beyond supply rails. It enables precision battery-level detection in space-grade power management systems.
For engineers reviewing the TLV3011AMDBVREP datasheet, TLV3011AMDBVREP pinout, TLV3011AMDBVREP application, or TLV3011AMDBVREP equivalent, key selection criteria include its open-drain output architecture, integrated reference accuracy (±1%), ultra-low IQ, extended temperature qualification, and SOT-23-6 package compatibility with high-reliability PCB layouts.
Technical Context
The TLV3011AMDBVREP implements a single-channel, rail-to-rail input comparator core with uncommitted open-drain output stage and a buffered 1.242-V series reference output. Its input stage supports common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V, enabling direct sensing across supply rails without external level-shifting.
The integrated reference delivers ±1% initial accuracy, 40–100 ppm/°C max drift over –55°C to 125°C, and sustains ±0.5 mA sourcing/sinking capability while maintaining stability with up to 10-nF capacitive load - enabling direct driving of ADC reference inputs or bias networks in isolated sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.8 V to 5.5 V - supports single-supply operation in 2.0-V to 5.0-V system domains including Li-ion battery monitoring and 3.3-V industrial I/O. |
| Quiescent Current | 2.8–5 μA at 5 V - enables multi-year battery life in always-on fault-detection circuits with sub-μA sleep-state leakage. |
| Reference Voltage | 1.242 V ±1% - provides stable, factory-trimmed threshold for precision window comparators or ADC reference scaling. |
| Input Offset Voltage | 0.5–15 mV - ensures ≤10-mV detection error in 1.2-V reference-based level-sensing applications. |
| Propagation Delay | 6–13.5 μs (100-mV overdrive) - delivers deterministic response for fast-fault shutdown in power converters and motor drives. |
| Common-Mode Range | (V–) – 0.2 V to (V+) + 0.2 V - allows direct connection to battery terminals or rail-sensing nodes without external resistive dividers. |
| Output Type | Open-drain - supports wired-OR logic, level translation to higher-voltage domains, and flexible pull-up configuration for noise-immune digital interfacing. |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm body), surface-mount, thermally enhanced for high-reliability aerospace and defense applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Comparator Output | Open-drain NMOS drain - requires external pull-up; sinks current when IN+ < IN−; used for interrupt assertion or latch enable. |
| V− (Pin 2) | Negative Supply Voltage | Ground or negative rail connection - defines lower reference for input common-mode and output swing. |
| IN+ (Pin 3) | Non-Inverting Input | High-impedance (10¹³ Ω ∥ 4 pF) node - accepts direct sensor output or filtered voltage without loading. |
| IN− (Pin 4) | Inverting Input | High-impedance (10¹³ Ω ∥ 4 pF) node - configured as threshold reference via resistor divider or internal 1.242-V REF. |
| REF (Pin 5) | Reference Voltage Output | Buffered 1.242-V source - supplies external circuitry (e.g., ADC ref, op-amp bias) with ≤1-mV/mA load regulation. |
| V+ (Pin 6) | Positive Supply Voltage | Primary power rail - powers both comparator core and reference; supports 1.8–5.5 V with full spec compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.242-V Reference | Eliminates external reference IC or precision resistor network, reducing BOM count and layout area in compact satellite subsystems. |
| –55°C to 125°C Extended Temp | Qualified per V62/07604-01XE for operation in orbital thermal vacuum and deep-space probe environments without derating. |
| 3.1-μA Max Quiescent Current | Enables continuous monitoring in energy-constrained payloads where average current must remain below 5 μA over mission lifetime. |
| Rail-to-Rail Input with 200-mV Beyond Rails | Permits direct connection to battery anode/cathode or DC-link capacitors without attenuation or clamping diodes. |
| Open-Drain Output | Supports multi-comparator wired-OR fault buses and interface to 1.8-V, 3.3-V, or 5-V logic families using a single pull-up resistor. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012AMDBVREP | Push-pull output, integrated hysteresis (2–8 mV), power-on reset, 1.65–5.5 V supply range. | Preferred for self-contained reset generation or noise-prone environments requiring built-in hysteresis. | Select when push-pull drive and automatic POR are required; not pin-compatible due to different output stage behavior. |
| LMV331M5X/NOPB | No integrated reference; 1.65–5.5 V supply; 120-ns propagation delay; 80-μA IQ; SOT-23-5 package. | Requires external reference or resistor divider; suited for high-speed, low-cost industrial monitoring where reference integration is optional. | Choose when speed >100 ns and cost sensitivity outweigh reference integration benefits; differs in pin count and lacks REF pin. |
Compared with TLV3012AMDBVREP, TLV3011AMDBVREP offers open-drain flexibility for bus arbitration but lacks hysteresis and POR; versus LMV331M5X/NOPB, it trades higher unit cost for reduced BOM count, lower IQ, and guaranteed reference performance across extreme temperatures.

FAQ
What is the maximum allowable supply voltage for TLV3011AMDBVREP?
The absolute maximum supply voltage for TLV3011AMDBVREP is 7 V, as specified in Section 6.1 of the datasheet. However, functional operation is guaranteed only within the recommended range of 1.8 V to 5.5 V. Exceeding 5.5 V may cause permanent damage or parametric shift, especially under extended temperature stress.
Does TLV3011AMDBVREP include hysteresis, and how is it implemented?
No, TLV3011AMDBVREP does not include internal hysteresis. Unlike the TLV3012-EP variant, this device relies on external hysteresis networks (e.g., positive feedback resistor from OUT to IN+) for noise immunity. The absence of built-in hysteresis preserves design flexibility for custom threshold control in precision monitoring applications.
Can the REF pin of TLV3011AMDBVREP drive an external ADC reference input?
Yes, the REF pin of TLV3011AMDBVREP can directly drive typical SAR ADC reference inputs (e.g., ADS8860, ADS7886) with ≤10-nF capacitance. Its 0.36–1 mV/mA sourcing load regulation and 100-ppm/°C max drift ensure stable reference performance across temperature and load variations encountered in flight electronics.
What is the input common-mode voltage range specification for TLV3011AMDBVREP?
The input common-mode voltage range for TLV3011AMDBVREP is (V–) – 0.2 V to (V+) + 0.2 V, verified across –55°C to 125°C. This rail-to-rail-plus margin enables direct connection to battery terminals or unregulated supply nodes without external level-shifting components.
Is TLV3011AMDBVREP qualified for space applications, and what certifications apply?
Yes, TLV3011AMDBVREP is an enhanced-product device qualified per VID V62/07604-01XE, featuring controlled baseline, single assembly/test/fab site, extended lifecycle support, and screening for space-grade reliability. It meets MIL-PRF-38535 Class V requirements and is rated for total ionizing dose (TID) up to 100 krad(Si).
