Product details
Overview
LMC6772QMMX/NOPB from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with open-drain outputs, designed for ultra-low-power battery-operated systems. It delivers 10 μA max supply current per comparator, operates from 2.7 V to 15 V, and supports −40°C to +125°C operation with AEC-Q100 qualification. It enables wired-OR logic level shifting in portable metering and monitoring circuits.
For engineers reviewing the LMC6772QMMX/NOPB datasheet, LMC6772QMMX/NOPB pinout, LMC6772QMMX/NOPB application, or LMC6772QMMX/NOPB equivalent, key selection criteria include its rail-to-rail input range exceeding supply rails, 420 ns propagation delay at 5 V/100 mV overdrive, open-drain output compatibility with 15 V pull-up, and automotive-grade temperature rating.
Technical Context
The LMC6772QMMX/NOPB integrates two independent comparators sharing no internal biasing-each draws ≤10 μA quiescent current and features rail-to-rail input common-mode voltage range extending beyond both V+ and V−. Its open-drain NMOS output stage allows flexible pull-up to any voltage ≤15 V, independent of V+, enabling interoperability across mixed-voltage domains.
It implements short-circuit protection limiting sink current to 40 mA, supports operation down to 2.7 V with guaranteed performance, and maintains <1 mV input offset voltage shift over full common-mode range due to 75 dB typical CMRR. The device is specified for −40°C to +125°C junction temperature, validated under AEC-Q100 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 10 μA max per comparator - enables multi-year battery life in always-on sensor monitors. |
| Supply Voltage Range | 2.7 V to 15 V - supports single-cell Li-ion (3.0 V), 5 V logic, and 12 V automotive rails without level-shifting. |
| Input Common-Mode Range | Exceeds V+ and V− by ≥200 mV - permits direct sensing of signals near ground or supply rails in low-voltage power monitoring. |
| Propagation Delay | 420 ns at 5 V, 100 mV overdrive - sufficient for RC timers, window comparators, and multivibrator clock generation up to ~1 MHz. |
| Output Type | Open-drain NMOS - enables wired-OR logic, bidirectional level translation, and pull-up to 15 V regardless of V+. |
| Temperature Range | −40°C to +125°C - qualified per AEC-Q100 Grade 1, suitable for under-hood automotive and industrial environments. |
| Input Offset Voltage | 10 mV max (LMC6772Q) - ensures reliable threshold detection in precision voltage monitoring applications. |

| 3 | IN+A | Non-inverting input of Comparator A - rail-to-rail capable, supports common-mode voltages beyond V+ and V−. |
| 4 | V− | Negative supply terminal - shared reference for both comparators; also serves as logic ground in single-supply use. |
| 5 | IN+B | Non-inverting input of Comparator B - identical electrical characteristics to IN+A. |
| 6 | IN−B | Inverting input of Comparator B - identical electrical characteristics to IN−A. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7012DR | Lower supply current (650 nA), but only 1.8–6 V supply range and −40°C to +125°C rating without AEC-Q100 validation. | Best suited for ultra-low-power IoT nodes where automotive qualification is unnecessary and supply is limited to ≤6 V. | Select TLV7012DR when sub-μA quiescent current dominates over wide-voltage or automotive compliance requirements. |
| LMC6762QMMX/NOPB | Same pinout and specs as LMC6772QMMX/NOPB but with push-pull (not open-drain) output stage; otherwise identical AEC-Q100 qualification and temperature range. | Required where active-high logic drive is needed without external pull-up resistors, e.g., driving microcontroller interrupt pins directly. | Choose LMC6762QMMX/NOPB only when wired-OR capability or external voltage-level translation is not required. |
Compared with TLV7012DR, LMC6772QMMX/NOPB trades higher quiescent current for wider voltage range and certified automotive reliability; compared with LMC6762QMMX/NOPB, it sacrifices push-pull drive for flexible open-drain interfacing-making it uniquely suited for mixed-voltage alarm and level-shifting functions.

FAQ
What is the maximum supply voltage for LMC6772QMMX/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC6772QMMX/NOPB is 16 V, but the recommended operating range is 2.7 V to 15 V. Operation at 15 V is fully characterized across temperature, including propagation delay, output sink current, and input offset voltage. Exceeding 16 V risks permanent damage per the Absolute Maximum Ratings table.
Does LMC6772QMMX/NOPB support rail-to-rail input voltage beyond the supply rails?
Yes, LMC6772QMMX/NOPB supports input common-mode voltages extending at least 200 mV beyond both V+ and V− across all supply voltages (2.7 V, 5 V, and 15 V). This is confirmed in Section 6.2 of the datasheet and enables direct interface to sensors or signals that swing outside the supply domain without clamping diodes or level-shifters.
Can LMC6772QMMX/NOPB outputs be pulled up to 15 V while operating from a 3.3 V supply?
Yes, the open-drain NMOS output stage of LMC6772QMMX/NOPB allows the output to be pulled up to any voltage up to 15 V, regardless of the comparator's own supply voltage. This is explicitly stated in the Description section and enables robust level translation-for example, driving a 12 V relay control line from a 3.3 V microcontroller domain.
Is LMC6772QMMX/NOPB pin-compatible with other variants in the LMC6772 family?
Yes, LMC6772QMMX/NOPB shares identical VSSOP-8 (DGK) pinout with all LMC6772xMMx variants, including LMC6772AIMMX/NOPB and LMC6772BIMMX/NOPB. Pin functions, spacing, and thermal pad configuration are identical-only electrical specifications (offset voltage, temperature grade, and qualification status) differ between variants.
What is the short-circuit current limit of LMC6772QMMX/NOPB?
LMC6772QMMX/NOPB provides short-circuit protection limiting output sink current to 40 mA. This value is specified in the Features list and verified in Section 5.4 (ISC = 45 mA typical at V+ = 15 V). Continuous short-circuit operation is not recommended, especially at elevated ambient temperatures, as it may exceed the 150°C maximum junction temperature.
