Product details
Overview
LMC6772AIMM/NOPB from Texas Instruments is a dual micropower rail-to-rail input CMOS comparator with open-drain outputs, 10 μA max supply current per channel, 2.7–15 V supply range, and 420 ns propagation delay at 5 V/100 mV overdrive - deployed in battery-powered metering systems and handheld electronics for ultra-low-power threshold detection.
For engineers reviewing the LMC6772AIMM/NOPB datasheet, LMC6772AIMM/NOPB pinout, LMC6772AIMM/NOPB application, or LMC6772AIMM/NOPB equivalent, key selection criteria include rail-to-rail input common-mode range exceeding supply rails, open-drain output compatibility with mixed-voltage logic interfaces, guaranteed operation down to 2.7 V, and −40°C to +85°C industrial temperature rating.
Technical Context
The LMC6772AIMM/NOPB integrates two independent comparators sharing no internal biasing interdependence, each featuring rail-to-rail input stages that operate with common-mode voltages extending 200 mV beyond both V+ and V− rails - enabling direct sensing of signals near ground or supply in single-supply configurations. Its open-drain NMOS output stage supports wired-OR logic and pull-up to any voltage ≤15 V, independent of the device's own supply.
Each comparator delivers 420 ns (tPLH) and 450 ns (tPHL) propagation delay at 100 mV overdrive and 5 V supply, with input offset voltage ≤8 mV (AI grade), input bias current ≤0.04 pA, and short-circuit protection rated at 40 mA - all while maintaining 12 μA typical supply current per channel at 2.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - enables direct use in 3 V, 5 V, and 12 V systems without level-shifting circuitry. |
| Max Supply Current | 25 μA per channel - ensures multi-year battery life in always-on monitoring circuits. |
| Input Common-Mode Range | Exceeds V+ and V− by ≥200 mV - allows direct interface to sensors or signals referenced outside supply rails. |
| Propagation Delay | 420 ns (tPLH) at 100 mV overdrive, 5 V - supports fast response in RC timers and zero-crossing detection. |
| Output Type | Open-drain NMOS - permits flexible pull-up to higher voltage rails (up to 15 V) and wired-OR bus configurations. |
| Input Offset Voltage | ≤8 mV (LMC6772AI grade) - sufficient for precision window comparators in metering applications. |
| ESD Tolerance | 1.5 kV HBM on output pins, 2 kV on other pins - meets basic handling robustness for industrial assembly. |

| 1 | OUTA | Open-drain output of Comparator A - requires external pull-up; sinks up to 40 mA. |
| 2 | INA− | Inverting input of Comparator A - rail-to-rail capable, <0.04 pA bias current. |
| 3 | INA+ | Non-inverting input of Comparator A - rail-to-rail capable, supports common-mode beyond supplies. |
| 4 | V− | Negative supply terminal - also serves as reference for input common-mode and output low state. |
| 5 | INB+ | Non-inverting input of Comparator B - electrically isolated from Comparator A inputs. |
| 6 | INB− | Inverting input of Comparator B - identical rail-to-rail performance and leakage specs as INA±. |
| 7 | OUTB | Open-drain output of Comparator B - independently controllable; supports wired-OR with OUTA. |

|---|---|
|
Use Scenario: Detecting undervoltage lockout (UVLO) and overvoltage conditions on 3.3 V or 5 V system rails. IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel monitors upper threshold, the other lower threshold. Use Value: Rail-to-rail inputs directly sense rail voltage without resistor dividers; open-drain outputs drive enable lines of PMICs or microcontroller reset inputs. |
Use Scenario: Monitoring remaining charge in single-cell Li-ion batteries (2.8–4.2 V range) for low-battery warnings. IC Role / Device Role / Timing Role: Comparator compares battery voltage against precision reference to trigger alert when voltage drops below 3.0 V. Use Value: 2.7 V minimum supply allows operation down to battery end-of-life; 10 μA quiescent current minimizes self-discharge impact. |
| RC-Based Precision Timers | Zero-Crossing Detection in AC Meters |
|
Use Scenario: Generating fixed-duration pulses using resistor-capacitor timing networks in portable test equipment. IC Role / Device Role / Timing Role: One-shot multivibrator built around LMC6772AIMM/NOPB and external R/C network. Use Value: 420 ns propagation delay ensures sub-microsecond timing accuracy; low input bias current prevents capacitor leakage errors. |
Use Scenario: Detecting AC line zero crossings in energy metering ICs for synchronized sampling and power factor calculation. IC Role / Device Role / Timing Role: Comparator compares scaled AC waveform to ground-referenced threshold with hysteresis. Use Value: Input common-mode range extending below ground enables direct AC coupling; rail-to-rail input rejects common-mode noise on transformer secondaries. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDR | Higher supply current (1.8 μA typical per channel vs. 12 μA typical for LMC6772AIMM/NOPB), faster propagation (1.5 μs), but narrower 1.8–5.5 V supply range. | Optimized for ultra-low-power 1.8–3.3 V systems; not suitable for 12 V industrial monitoring. | Select TLV3702IDR only when operating strictly below 5.5 V and sub-μA quiescent current is critical. |
| LMV393MMX/NOPB | Higher supply current (80 μA per channel), rail-to-rail output (push-pull), no rail-to-rail input - input common-mode limited to V− to V+ −1.5 V. | Better for driving capacitive loads directly; unsuitable for sensing signals near V+ or below V−. | Choose LMV393MMX/NOPB when push-pull output is required and input signals stay within standard CMVR. |
Compared with TLV3702IDR and LMV393MMX/NOPB, the LMC6772AIMM/NOPB uniquely balances ultra-low supply current, rail-to-rail input beyond supplies, wide 2.7–15 V operation, and open-drain flexibility - making it the only option among the three viable for battery-backed metering and mixed-voltage industrial interfaces.

FAQ
What is the maximum supply voltage for the LMC6772AIMM/NOPB?
The LMC6772AIMM/NOPB supports a maximum supply voltage of 16 V absolute maximum rating, with guaranteed operation up to 15 V across its full temperature range. Exceeding 15 V may compromise long-term reliability, especially when sinking output current into loads referenced above V+.
Does the LMC6772AIMM/NOPB have rail-to-rail output capability?
No, the LMC6772AIMM/NOPB features open-drain NMOS outputs only - it does not provide rail-to-rail voltage swing. The output can be pulled high to any voltage ≤15 V via an external pull-up resistor, but cannot actively drive high. For push-pull output, refer to the LMC6762 variant.
Can the LMC6772AIMM/NOPB operate from a 2.7 V single supply?
Yes, the LMC6772AIMM/NOPB is fully specified and guaranteed to operate from a 2.7 V single supply, delivering 420 ns tPLH propagation delay and rail-to-rail input common-mode range extending 200 mV beyond both supply rails - ideal for coin-cell or single-Li-ion powered devices.
What is the input bias current specification for the LMC6772AIMM/NOPB?
The LMC6772AIMM/NOPB exhibits an input bias current of ≤0.04 pA (typical) at 5 V supply, ensuring negligible loading on high-impedance sensor sources such as thermistors, photodiodes, or pH electrodes - critical for precision measurement front-ends.
Is the LMC6772AIMM/NOPB pin-compatible with the LMC6772QMM/NOPB?
Yes, the LMC6772AIMM/NOPB and LMC6772QMM/NOPB share identical VSSOP-8 (DGK) packaging, pinout, and electrical functionality - differing only in temperature rating (−40°C to +85°C vs. −40°C to +125°C) and automotive qualification status; no PCB changes are required for substitution within industrial temperature limits.
