Product details
Overview
LMV331M5X-TI from Texas Instruments is a single, low-voltage, rail-to-ground input comparator in a 5-pin SOT-23 package, delivering 60 µA supply current per channel, 200 ns propagation delay at 5 V, and input common-mode range extending to ground - enabling precise threshold detection in battery-powered sensor interfaces and portable power management circuits.
For engineers reviewing the LMV331M5X-TI datasheet, LMV331M5X-TI pinout, LMV331M5X-TI application, or LMV331M5X-TI equivalent, key selection considerations include open-collector output compatibility with mixed-voltage logic, −40°C to +85°C industrial temperature operation, ground-sensing input capability, and verified performance at both 2.7 V and 5 V supply rails.
Technical Context
The LMV331M5X-TI implements a bipolar-input, open-collector output architecture optimized for low-voltage analog-to-digital decision-making. Its input stage supports common-mode voltages down to −0.1 V (below ground) and up to 4.2 V (at 5 V supply), while the output stage sinks up to 10 mA with 200 mV saturation voltage at 4 mA load.
It operates across 2.7 V–5 V single-supply rails and features internal ESD protection (±800 V HBM), ensuring robustness in handheld and embedded systems. Propagation delay varies with overdrive: 200 ns typical at 100 mV overdrive (5 V), rising to 600 ns at 10 mV overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct integration into Li-ion (3.0–3.7 V) and USB-powered (5 V) systems without level-shifting. |
| Input Offset Voltage | 1.7 mV (min), 7 mV (typ) - enables accurate threshold detection within ±10 mV windows without external trimming. |
| Supply Current per Channel | 60 µA (typ) at 5 V - allows continuous operation for >1 year on a 200 mAh coin cell in wake-up monitoring applications. |
| Propagation Delay | 200 ns (typ, high-to-low, 100 mV overdrive, 5 V) - suitable for sub-1 MHz signal conditioning and fast-response power sequencing. |
| Input Common-Mode Range | −0.1 V to 4.2 V (at 5 V supply) - permits direct sensing of signals referenced to system ground, including battery voltage monitoring. |
| Output Configuration | Open-collector - enables wired-OR logic, level translation to 1.8/3.3 V domains, and interface with TTL/CMOS loads via external pull-up. |
| Saturation Voltage | 200 mV (max, ISINK = 4 mA) - ensures reliable low-state recognition by downstream logic even under moderate load. |
Pinout & Package
LMV331M5X-TI is housed in a 5-pin SOT-23 package (2.90 mm × 1.6 mm body size), optimized for space-constrained PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - +IN | Noninverting Input | Accepts analog input signals; supports common-mode range down to −0.1 V for ground-referenced sensing. |
| 2 - GND / V− | Negative Supply / Ground Reference | Return path for supply and input signals; serves as reference for input common-mode and output saturation. |
| 3 - −IN | Inverting Input | Receives reference or feedback voltage; used with +IN to define switching threshold in comparator configurations. |
| 4 - OUT | Open-Collector Output | Sinks current only; requires external pull-up resistor (1–10 kΩ) to VCC or another logic rail for proper HIGH/LOW states. |
| 5 - V+ | Positive Supply | Single-supply rail (2.7–5 V); powers internal circuitry and defines upper limit of input common-mode and output swing. |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Input common-mode extends to −0.1 V below ground, enabling direct measurement of signals tied to system ground (e.g., battery voltage dividers). |
| Low quiescent current | 60 µA typical per channel at 5 V - reduces standby power in always-on monitoring circuits such as lid-open detection or battery fuel gauging. |
| Fast propagation response | 200 ns typical (100 mV overdrive, 5 V) - supports real-time overvoltage/undervoltage lockout in DC-DC converter supervision. |
| Open-collector output | Compatible with 1.8 V, 3.3 V, and 5 V logic families via configurable pull-up; enables wired-OR for multi-threshold alarm aggregation. |
| Industrial temperature range | −40°C to +85°C operation - validated for use in automotive cabin modules, industrial handhelds, and outdoor IoT edge nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV331IDBVR | Lower supply current (55 µA typ), higher input bias current (1 pA vs. 25 nA), same SOT-23-5 package and open-collector output. | Better suited for ultra-low-power, high-impedance sensor interfaces where input leakage must be minimized. | Choose TLV331IDBVR when input bias current <1 pA is critical and supply current reduction justifies slightly higher cost. |
| LM393DGKR | Wider supply range (2–36 V), higher supply current (250 µA/ch), SOIC-8 package - not pin-compatible with SOT-23-5. | Designed for industrial 12/24 V systems; lacks ground-sensing input (common-mode starts at 0 V, not −0.1 V). | Choose LM393DGKR only for legacy 5–30 V designs requiring drop-in replacement of LM393; not suitable for space- or low-voltage-constrained layouts. |
Compared with LMV331M5X-TI, TLV331IDBVR offers superior input bias performance for high-Z sources but shares identical pinout and functional behavior, whereas LM393DGKR provides broader voltage tolerance at the expense of quiescent power and package compatibility - making LMV331M5X-TI the optimal balance for modern 2.7–5 V portable systems.

FAQ
What is the operating supply voltage range for the LMV331M5X-TI?
The LMV331M5X-TI operates from 2.7 V to 5 V on a single supply. It is fully specified and tested across this range, with electrical characteristics guaranteed at both 2.7 V and 5 V per the SNOS018H datasheet. Operation outside this range may result in undefined behavior or damage.
Does the LMV331M5X-TI support input voltages below ground?
Yes, the LMV331M5X-TI features a ground-sensing input stage with an input common-mode voltage range extending to −0.1 V below ground (V−) at 5 V supply. This allows direct interfacing with signals referenced to system ground, such as resistive divider outputs from battery terminals.
What is the maximum output sink current for the LMV331M5X-TI?
The LMV331M5X-TI can sink up to 10 mA while maintaining output saturation voltage ≤400 mV (max) at 5 V supply and 25°C. At 4 mA load, saturation voltage is guaranteed ≤200 mV, enabling reliable interfacing with standard TTL and CMOS logic inputs.
Is the LMV331M5X-TI pin-compatible with other comparators in the LMV3xx-N family?
No - the LMV331M5X-TI (SOT-23-5) is not pin-compatible with LMV393-N (SOIC-8/VSSOP-8) or LMV339-N (SOIC-14/TSSOP-14). However, its 5-pin SOT-23 layout matches the LMV331-N variants and shares identical pin functions (V+, −IN, +IN, OUT, V−) across all SC70/SOT-23 packaged versions.
Can the LMV331M5X-TI drive a 3.3 V logic input directly?
Yes, the LMV331M5X-TI's open-collector output can drive 3.3 V logic when its external pull-up resistor is connected to a 3.3 V rail. The output will pull low to ≤200 mV (ensured) and float high to 3.3 V, satisfying VIH/VIL thresholds for standard 3.3 V CMOS inputs without additional level-shifting circuitry.
