Product details
Overview
LMV7239QM7X/NOPB from Texas Instruments is an automotive-grade, ultra-low-power, rail-to-rail input comparator with 75 ns propagation delay, 65 µA supply current at 5 V, and dual-output capability (push-pull + open-drain configurable via external pull-up). It operates from 2.7 V to 5.5 V and supports ground- and supply-sensing in battery-powered automotive sensor interfaces.
For engineers reviewing the LMV7239QM7X/NOPB datasheet, LMV7239QM7X/NOPB pinout, LMV7239QM7X/NOPB application, or LMV7239QM7X/NOPB equivalent, key selection criteria include propagation delay vs. overdrive, rail-to-rail input common-mode range extending −0.2 V to VCC + 0.2 V, push-pull output eliminating external pull-up requirements, and AEC-Q100 Grade 1 qualification for −40°C to +125°C ambient operation.
Technical Context
The LMV7239QM7X/NOPB uses a complementary PNP/NPN input stage enabling > rail-to-rail common-mode operation (−0.2 V to VCC + 0.2 V), critical for direct ground- and VCC-referenced sensing. Its push-pull output delivers ±4 mA sinking/sourcing capability without external components, unlike open-drain comparators requiring pull-up resistors.
Propagation delay remains stable across capacitive loads up to 15 pF and varies only 10 ns (75–85 ns) from 20 mV to 100 mV input overdrive at 5 V - confirming high-speed decision-making under low-signal conditions typical in zero-crossing and window detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 75 ns at 100 mV overdrive, 5 V supply, 15 pF load - enables sub-13 MHz sampling in high-speed threshold detection |
| Supply Current | 65 µA typical at 5 V - supports multi-year battery life in always-on automotive body electronics |
| Input Common-Mode Range | −0.2 V to VCC + 0.2 V - allows direct sensing of signals below ground (e.g., shunt current monitoring) and above supply rail |
| Output Type | Push-pull - eliminates need for external pull-up resistor, reducing BOM count and PCB area in space-constrained modules |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with 3.3 V microcontrollers and legacy 5 V automotive systems |
| Input Offset Voltage | ±1 mV typical at 5 V - ensures accurate threshold detection in precision window comparators |
| ESD Rating | HBM ±1000 V, CDM ±750 V (DBV package) - meets AEC-Q100 stress requirements for automotive assembly environments |
Pinout & Package

| 3 - IN+ | Non-inverting Input | High-impedance input (400 nA max bias current) accepting signals up to VCC + 0.2 V - used for reference or signal monitoring |
| 4 - IN− | Inverting Input | High-impedance input with identical CMVR - used for feedback or threshold comparison in hysteresis circuits |
| 5 - V+ | Positive Supply | Power pin accepting 2.7–5.5 V - decoupling capacitor required within 2 mm for stable high-speed switching |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Automotive Window Comparator | Battery Voltage Monitor |
|---|---|

| Zero-Crossing Detector | High-Speed Line Receiver |
Use Scenario: Detecting AC waveform zero crossings in automotive alternator field control and regenerative braking feedback loops. IC Role / Device Role / Timing Role: Inverting configuration with hysteresis rejects noise near 0 V crossing point while delivering clean TTL-compatible edges. Use Value: 75 ns propagation delay ensures phase accuracy <0.5° at 1 kHz - critical for synchronous rectification timing. | Use Scenario: Receiving differential CAN FD or LIN bus signals in gateway ECUs where EMI immunity and fast edge detection are essential. IC Role / Device Role / Timing Role: Converts analog bus voltage swings into clean digital logic levels with minimal jitter and no external bias network. Use Value: Rail-to-rail input accepts full 0–5 V bus swing; push-pull output drives FPGA I/O banks directly at >10 Mbps data rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211QDR | Higher supply current (115 µA), slower propagation delay (110 ns), same AEC-Q100 Grade 1 rating | Limited to lower-speed diagnostics due to 110 ns tPD; less suitable for real-time motor control feedback | Select when cost sensitivity outweighs speed/power trade-offs and 110 ns delay is acceptable |
| LMV7271QMF/NOPB | Same 75 ns tPD, but open-drain only output requiring external pull-up; 75 µA supply current | Requires additional resistor and PCB trace; unsuitable for space-constrained modules where SC70 footprint is critical | Select only if open-drain interface is mandatory for wired-OR bus architectures |
Compared with TLV7211QDR and LMV7271QMF/NOPB, LMV7239QM7X/NOPB uniquely combines 75 ns speed, 65 µA ultra-low power, and push-pull output in an AEC-Q100 qualified SC70 package - making it optimal for next-generation automotive sensor signal conditioning where board area, power, and timing margins are simultaneously constrained.

FAQ
What is the maximum operating temperature for LMV7239QM7X/NOPB?
The LMV7239QM7X/NOPB is AEC-Q100 Grade 1 qualified with guaranteed operation from −40°C to +125°C ambient temperature. Junction temperature must not exceed 150°C - thermal design must account for θJA = 478°C/W (SC70) and power dissipation under worst-case load conditions. This rating makes LMV7239QM7X/NOPB suitable for under-hood and transmission control unit applications.
Does LMV7239QM7X/NOPB require an external pull-up resistor?
No, LMV7239QM7X/NOPB features an integrated push-pull output stage capable of sourcing and sinking ≥4 mA, eliminating the need for an external pull-up resistor. This distinguishes it from open-drain comparators like LMV7271QMF/NOPB and reduces BOM count, PCB area, and potential signal integrity issues caused by resistor parasitics - a key advantage in compact automotive modules.
Can LMV7239QM7X/NOPB operate from a 3.3 V supply?
Yes, LMV7239QM7X/NOPB is fully specified for supply voltages from 2.7 V to 5.5 V. At 3.3 V, it maintains 75 ns propagation delay (typical), 65 µA supply current (typical), and rail-to-rail input operation from −0.2 V to 3.5 V - making it ideal for interfacing with 3.3 V microcontrollers in modern automotive domain controllers without level shifters.
What is the input common-mode voltage range of LMV7239QM7X/NOPB?
The LMV7239QM7X/NOPB has a greater-than-rail-to-rail input common-mode voltage range of −0.2 V to VCC + 0.2 V, verified across temperature and supply voltage. This allows direct sensing of signals below ground (e.g., current-sense shunt monitoring) and above the positive rail (e.g., battery voltage tracking), which is essential for robust fault detection in automotive power systems.
Is LMV7239QM7X/NOPB pin-compatible with other comparators in TI's portfolio?
LMV7239QM7X/NOPB uses the standard 5-pin SC70 (DGK) pinout: Pin 1 = VOUT, Pin 2 = V−, Pin 3 = IN+, Pin 4 = IN−, Pin 5 = V+. It shares this pinout with LMV7271QMF/NOPB and TLV7211QDR, enabling drop-in replacement in many layouts - however, functional differences (e.g., push-pull vs. open-drain output) require verification of downstream logic interface compatibility before substitution.
