Product details
Overview
LMV331M7X/NOPB from Texas Instruments is a single, low-voltage, rail-to-ground input comparator with open-collector output, 60 µA typical supply current per channel, 200 ns propagation delay at 5 V, and operation from 2.7 V to 5 V - used in battery-powered voltage monitoring and portable power management circuits.
For engineers reviewing the LMV331M7X/NOPB datasheet, LMV331M7X/NOPB pinout, LMV331M7X/NOPB application, or LMV331M7X/NOPB equivalent, key selection criteria include input common-mode range extending to ground, low saturation voltage (200 mV @ 4 mA), SC70-5 package footprint, and compatibility with CMOS/TTL logic interfaces via external pull-up.
Technical Context
The LMV331M7X/NOPB implements a bipolar-input, BiCMOS-output comparator architecture optimized for low-voltage operation. Its input stage supports common-mode voltages down to −0.1 V (below ground) and up to 4.2 V at 5 V supply, enabling direct sensing of signals referenced to system ground.
The open-collector output requires an external pull-up resistor (1–10 kΩ) and enables wired-OR configurations, level translation across voltage domains ≤ V+, and direct interfacing with TTL/CMOS inputs - all while maintaining 200 ns propagation delay and 200 mV saturation voltage under 4 mA sink load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-cell Li-ion (3.0–3.7 V) and dual-cell alkaline (3.0–3.2 V) systems without regulation |
| Supply Current (Typ) | 60 µA - enables multi-year operation in always-on battery monitors and wake-up comparators |
| Propagation Delay | 200 ns (5 V, 100 mV overdrive) - suitable for fast threshold detection in power sequencing and fault response |
| Input Offset Voltage | 7 mV (typ) - defines minimum detectable differential voltage without trimming |
| Saturation Voltage | 200 mV @ ISINK = 4 mA - ensures reliable low-level logic '0' drive into standard CMOS loads |
| Input Common-Mode Range | −0.1 V to 4.2 V (5 V supply) - allows direct ground-referenced signal comparison without level shifters |
| ESD Rating (HBM) | ±800 V - meets basic handling robustness requirements for consumer electronics assembly |
Pinout & Package
LMV331M7X/NOPB is housed in a 5-pin SC70 package (2.00 mm × 1.25 mm), offering ~50% area reduction versus SOT-23-5. The SC70 footprint supports high-density portable PCB layouts while maintaining thermal resistance (RθJA = 478°C/W) appropriate for low-power operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+IN) | Noninverting Input | Accepts analog signal to be compared against reference; supports common-mode down to −0.1 V |
| 2 (V−) | Negative Supply | Ground connection in single-supply operation; must be tied to system GND |
| 3 (−IN) | Inverting Input | Receives reference voltage or threshold; matched bias current minimizes offset error |
| 4 (OUT) | Open-Collector Output | Sinks current only; requires external pull-up to define logic HIGH level and interface voltage |
| 5 (V+) | Positive Supply | Connects to main system rail (2.7–5 V); powers internal circuitry and sets output swing ceiling |
Key Features
| Feature | Design Value |
|---|---|
| Ground-sensing input stage | Enables direct comparison of signals referenced to system ground - eliminates need for level-shifting resistors in battery voltage monitoring |
| Open-collector output | Permits wired-OR logic, mixed-voltage interfacing (e.g., 3.3 V comparator driving 5 V TTL), and flexible pull-up selection (1–10 kΩ) |
| Low quiescent current | 60 µA typical draw allows integration into ultra-low-power wake-up circuits without compromising battery life |
| Fast propagation response | 200 ns delay at full overdrive supports real-time fault detection in DC-DC converter OVP/UVP protection |
| Industrial temperature range | −40°C to +85°C operation ensures reliability in handheld, automotive accessory, and industrial sensor nodes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV331DBVR | Lower supply current (55 µA typ), same SC70-5 package, but 360 ns propagation delay at 5 V | Preferred for ultra-low-power sleep-mode monitoring where speed < 300 ns suffices | Select TLV331DBVR when minimizing µA per hour outweighs need for sub-250 ns response |
| LM393DR | Wider supply range (2–36 V), SOIC-8 package, higher supply current (500 µA), slower (1.3 µs delay) | Suitable for industrial 24 V systems requiring robustness over portability | Choose LM393DR only when legacy 24 V compatibility or board-level drop-in replacement is mandatory |
Compared with TLV331DBVR, LMV331M7X/NOPB delivers 200 ns speed at modest current cost; versus LM393DR, it trades wide-VCC support for 87% lower current and 85% faster response - making it optimal for space-constrained, battery-operated 3–5 V designs.

FAQ
What is the maximum supply voltage for LMV331M7X/NOPB?
The absolute maximum supply voltage for LMV331M7X/NOPB is 5.5 V, but the recommended operating range is 2.7 V to 5 V. Operation above 5 V risks permanent damage, and performance parameters like propagation delay and input offset are only specified and ensured within the 2.7–5 V range per the SNOS018H datasheet.
Does LMV331M7X/NOPB support rail-to-rail input?
LMV331M7X/NOPB does not support full rail-to-rail input - its input common-mode range extends from −0.1 V to 4.2 V at 5 V supply, meaning it accepts signals down to 0.1 V below ground and up to 0.8 V below V+, but not to the positive rail. This ground-sensing capability is sufficient for most single-supply applications without requiring level shifting.
Can LMV331M7X/NOPB drive a MOSFET gate directly?
No, LMV331M7X/NOPB cannot drive a MOSFET gate directly because its open-collector output only sinks current - it lacks a pull-up structure to source voltage. To drive a MOSFET gate, an external pull-up resistor to VGS is required, and gate capacitance must be considered; for high-speed switching, a dedicated gate driver is recommended instead.
What pull-up resistor value is recommended for LMV331M7X/NOPB?
Texas Instruments specifies a recommended pull-up resistor range of 1 kΩ to 10 kΩ for LMV331M7X/NOPB. A 4.7 kΩ resistor is commonly used to balance rise time (with typical load capacitance < 20 pF) and power dissipation (< 0.5 mW at 5 V), while ensuring sufficient drive strength for CMOS/TTL logic thresholds.
Is LMV331M7X/NOPB pin-compatible with other comparators in the LMV33x family?
LMV331M7X/NOPB is not pin-compatible with LMV339-N or LMV393-N due to differing channel counts and pinouts - it uses a 5-pin SC70 layout (V+, −IN, +IN, OUT, V−), whereas LMV393-N uses 8-pin SOIC/VSSOP and LMV339-N uses 14-pin packages. However, its SC70 pinout matches other single comparators like TLV331DBVR, enabling direct PCB substitution in that footprint.
