Product details
Overview
LMV7275MGX/NOPB from Texas Instruments is a single-channel, rail-to-rail input, low-power comparator with open-drain output, specified for 1.8 V to 5.5 V supply operation, delivering 9 µA supply current, 4 mV max input offset voltage, and 880 ns propagation delay (20-mV overdrive at 1.8 V), used in battery-powered voltage monitoring and level-shifting interfaces.
For engineers reviewing the LMV7275MGX/NOPB datasheet, LMV7275MGX/NOPB pinout, LMV7275MGX/NOPB application, or LMV7275MGX/NOPB equivalent, key selection criteria include open-drain output compatibility with mixed-voltage buses, rail-to-rail input range extending 0.1 V beyond rails, ultra-low quiescent current for multi-year battery life, and guaranteed 4 mV VOS for precision threshold detection.
Technical Context
The LMV7275MGX/NOPB uses a BiCMOS process with paralleled PNP/NPN input stages to achieve −0.1 V to V+ + 0.1 V common-mode input range, enabling direct sensing of signals near ground or supply rails. Its bipolar input delivers 10 nA bias current and 200 pA offset current, supporting high-impedance reference networks.
Unlike the push-pull-output LMV7271/LMV7272, the LMV7275MGX/NOPB omits the PMOS pull-up device, resulting in an open-drain output that sinks up to 1.5 mA and exhibits only 2 pA leakage at VO = 5 V - enabling wired-OR logic and level translation up to 5.5 V independent of its own supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct integration into Li-ion, coin-cell, and 3.3/5 V systems without regulation. |
| Supply Current | 9 µA typical at 1.8 V - enables >10-year battery life in always-on wake-up comparators. |
| Input Offset Voltage | Max 4 mV - ensures reliable 10–50 mV hysteresis design without trimming for portable power monitors. |
| Propagation Delay | 880 ns at 20-mV overdrive (1.8 V) - sufficient for slow-speed window detection and brownout response. |
| Input Common-Mode Range | −0.1 V to V+ + 0.1 V - allows direct connection to 0 V-referenced sensors or rail-sensing circuits. |
| Output Leakage | 2 pA at VO = 5 V - preserves high-impedance bus integrity in multi-comparator wired-OR configurations. |
| ESD Rating (HBM) | ±2000 V - meets IEC 61000-4-2 Level 2 for handheld and wearable end-equipment. |
Pinout & Package
SOT-23-5 (DGK) package: 1.60 mm × 2.90 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Noninverting Input | High-impedance node (10 nA IB) accepting signals from 0.1 V below V− to 0.1 V above V+. |
| GND | Negative Supply | Reference return for both input stage and output sink; must be low-impedance for stable VOS. |
| −IN | Inverting Input | Differential partner to +IN; matched bias current enables precision differential sensing. |
| VOUT | Open-Drain Output | Active-low sinking node; requires external pull-up to any voltage ≤5.5 V for level shifting. |
| V+ | Positive Supply | Power input (1.8–5.5 V); bypass capacitor mandatory to suppress shoot-through transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range | Operates with inputs from −0.1 V to V+ + 0.1 V - eliminates need for level-shifting op-amps in supply-monitoring circuits. |
| Open-drain output | Enables wired-OR bus topology and interface to higher-voltage logic (up to 5.5 V) without level translators. |
| Ultra-low supply current | 9 µA typical at 1.8 V - reduces average system power by >95% vs. standard comparators in duty-cycled wake-up designs. |
| Low input bias current | 10 nA typical - preserves accuracy in high-resistance voltage-divider references (e.g., 1 MΩ dividers). |
| Guaranteed 4 mV VOS | Ensures consistent switching thresholds across temperature and supply voltage - critical for battery voltage cutoffs. |
Applications
| Battery Voltage Monitoring | Wearable Device Wake-Up |
|---|---|
Use Scenario: Detecting Li-ion cell voltage drop below 3.0 V to trigger MCU sleep mode exit or charger enable. IC Role / Device Role / Timing Role: Precision threshold detector comparing battery voltage against internal or resistor-divided reference. Use Value: 4 mV VOS tolerance ensures ±15 mV total error budget, enabling accurate 3.0 V cutoff without calibration. | Use Scenario: Monitoring photodiode or accelerometer output to initiate BLE transmission upon motion or light event. IC Role / Device Role / Timing Role: Low-power wake-up comparator driving MCU interrupt pin via open-drain output. Use Value: 9 µA supply current extends coin-cell lifetime beyond 2 years in intermittent-sense applications. |
| Level-Shifting Interface | Multi-Supply System Alert Bus |
Use Scenario: Converting 1.8 V logic-level sensor alert to 3.3 V or 5 V microcontroller input. IC Role / Device Role / Timing Role: Open-drain translator with pull-up to target rail - no direction control or timing skew. Use Value: Output can be pulled to any voltage ≤5.5 V, eliminating discrete MOSFET level shifters in mixed-supply PCBs. | Use Scenario: Combining fault signals (overvoltage, overtemperature, memory error) onto shared system-alert line. IC Role / Device Role / Timing Role: Wired-OR node where any LMV7275MGX/NOPB output low asserts global interrupt. Use Value: 2 pA output leakage prevents false assertion on shared bus; compatible with 10 kΩ pull-up for <1 µs rise time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDBVR | Push-pull output, 11 µA supply current, 6.5 mV VOS max, same SOT-23-5 package. | Cannot perform wired-OR or level shift; requires dedicated pull-up for logic-high assertion. | Select when board space is constrained and open-drain functionality is unnecessary. |
| MAX9021AXK+T | Open-drain output, 12 µA supply current, 5 mV VOS max, SC70-5 package (1.25 × 2.00 mm). | Smaller footprint but lower ESD rating (±1000 V HBM); not qualified for automotive temp range. | Select when PCB area is premium and industrial temp range (−40°C to +85°C) suffices. |
Compared with TLV7211IDBVR and MAX9021AXK+T, the LMV7275MGX/NOPB uniquely combines ultra-low 9 µA current, guaranteed 4 mV VOS, and robust ±2000 V HBM protection in a production-proven SOT-23-5 package - making it optimal for long-life, mixed-voltage, and ESD-sensitive portable systems.

FAQ
What is the maximum supply voltage for LMV7275MGX/NOPB?
The absolute maximum supply voltage for LMV7275MGX/NOPB is 6 V, but the recommended operating range is 1.8 V to 5.5 V per the datasheet. Operation at 5.5 V ensures full specification compliance across temperature, while exceeding 6 V risks permanent damage to the input ESD structures and internal BiCMOS junctions.
Does LMV7275MGX/NOPB support rail-to-rail input at 1.8 V supply?
Yes, LMV7275MGX/NOPB supports rail-to-rail input operation from −0.1 V to V+ + 0.1 V at all supply voltages including 1.8 V. This is achieved via dual PNP/NPN input pairs, allowing direct sensing of signals at ground or near V+ - critical for low-voltage battery monitoring where reference points lie at supply extremes.
Can LMV7275MGX/NOPB drive a 5 V logic input while powered from 1.8 V?
Yes, LMV7275MGX/NOPB's open-drain output allows its VOUT pin to be pulled up to 5 V (≤5.5 V) while operating from 1.8 V. The output transistor sinks current only; no voltage is generated internally. This enables true level shifting without additional components - confirmed by 2 pA leakage spec at VO = 5 V.
What is the typical propagation delay of LMV7275MGX/NOPB at 2.7 V supply?
At 2.7 V supply and 20-mV overdrive, LMV7275MGX/NOPB exhibits 1200 ns typical tPHL (high-to-low) and 1300 ns typical tPLH (low-to-high) propagation delay with 50 pF//5 kΩ load. These values increase versus 1.8 V due to reduced drive strength, but remain suitable for non-critical timing applications like power-good sequencing.
Is LMV7275MGX/NOPB pin-compatible with LMV7271MGX/NOPB?
No, LMV7275MGX/NOPB is not pin-compatible with LMV7271MGX/NOPB despite identical SOT-23-5 packaging and pin numbering. Both share +IN, GND, −IN, VOUT, and V+ pin assignments, but LMV7271MGX/NOPB has a push-pull output while LMV7275MGX/NOPB has open-drain - requiring different external pull-up configuration and preventing direct substitution without schematic revision.
