Product details
Overview
LMC7215QIM5X/NOPB from Texas Instruments is an ultra-low-power, rail-to-rail CMOS comparator with push-pull output, 0.7 μA typical supply current, 2 V to 8 V supply range, and input common-mode voltage extending beyond both rails. It operates across −40°C to +85°C and is qualified to AEC-Q100 Grade 3 for automotive sensing and monitoring circuits.
For engineers reviewing the LMC7215QIM5X/NOPB datasheet, LMC7215QIM5X/NOPB pinout, LMC7215QIM5X/NOPB application, or LMC7215QIM5X/NOPB equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated SOT-23-5 pinout, automotive-grade reliability notes, and two confirmed alternative comparators with documented functional and application differences.
Technical Context
The LMC7215QIM5X/NOPB implements a high-gain (140 dB) CMOS comparator core with rail-to-rail input stage enabling operation down to 2 V supply while maintaining >50 dB CMRR over full common-mode range. Its push-pull output drives up to 45 mA sink/source at 5 V without external pull-up, eliminating static power loss in load switching.
Input protection diodes allow safe overvoltage tolerance up to V+ + 0.3 V and V− − 0.3 V, supporting direct connection to supply rails for current/voltage sensing. Propagation delay is 24 μs (high-to-low) and 24 μs (low-to-high) at 10 mV overdrive with 5 V supply - optimized for battery-powered timing and alarm functions where microamp-level quiescent current is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 0.7 μA typical - enables multi-year operation on coin-cell batteries in always-on monitoring systems. |
| Supply Voltage Range | 2 V to 8 V - supports single-cell Li-ion (3.0–4.2 V), dual-AA (2.4–3.2 V), and 5 V logic rails without regulation. |
| Input Common-Mode Range | V− −0.2 V to V+ +0.3 V - permits direct sensing of supply voltage or current-sense resistor voltages exceeding rail limits. |
| Output Type | Push-pull - eliminates need for external pull-up resistor, reducing BOM count and static power in low-duty-cycle wake-up circuits. |
| Propagation Delay | 24 μs @ 10 mV overdrive, 5 V - sufficient for RC timers, window comparators, and slow-varying threshold detection in metering. |
| Output Drive | 45 mA sink/source @ 5 V - directly drives LEDs, small relays, or logic inputs without buffer stages. |
| Latch-up Immunity | >300 mA - withstands transient ESD and fault currents in automotive and industrial environments without damage. |
Pinout & Package
LMC7215QIM5X/NOPB is housed in a 5-pin SOT-23 package (DBV drawing), 2.9 mm × 1.6 mm × 1.45 mm, RoHS-compliant, moisture sensitivity level 1 (260°C reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Non-inverting input | High-impedance CMOS node (5 fA typical bias); accepts signals beyond V+ or below V− for rail-exceeding sensing. |
| 2 - GND | Ground reference | Return path for supply and output; must be low-impedance to maintain latch-up immunity and propagation stability. |
| 3 - OUT | Push-pull output | CMOS totem-pole stage; actively drives high/low - no external pull-up needed; sinks/sources up to 45 mA @ 5 V. |
| 4 - V+ | Positive supply | Accepts 2–8 V; internal regulation not required; thermal derating applies above 5 V with heavy output loading. |
| 5 - IN− | Inverting input | Matched to IN+ in offset and bias; enables precise differential or single-ended threshold comparisons. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with beyond-rail tolerance | Enables direct connection to V+ for supply monitoring or high-side current sensing without level-shifting circuitry. |
| 0.7 μA supply current | Reduces average system power by >90% vs. standard comparators, extending battery life in portable and remote sensors. |
| 45 mA output drive @ 5 V | Eliminates need for discrete driver transistors when interfacing with LEDs, piezo buzzers, or TTL/CMOS loads. |
| AEC-Q100 Grade 3 qualification | Validated for automotive cabin electronics including HVAC controls, body modules, and battery management monitors. |
| 300 mA latch-up immunity | Ensures robustness against ESD events and power-rail transients in noisy automotive and industrial power domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDBVR | 0.6 μA supply current, 1.8–5.5 V supply, open-drain output only | Lacks push-pull drive; requires external pull-up for logic-high output; unsuitable for direct LED driving | Select TLV3691IDBVR only when open-drain flexibility and lower supply minimum are prioritized over output drive capability |
| LMC7225QIM5X/NOPB | Same package and pinout; open-drain output; 0.7 μA supply current; supports level-shifting up to 15 V | Requires external pull-up; used where output must interface with higher-voltage logic (e.g., 12 V MCU I/O) | Choose LMC7225QIM5X/NOPB instead of LMC7215QIM5X/NOPB only when level-shifting or wired-OR functionality is required |
Compared with TLV3691IDBVR and LMC7225QIM5X/NOPB, the LMC7215QIM5X/NOPB uniquely combines ultra-low supply current, rail-to-rail input, and true push-pull output - making it the only option among the three capable of driving moderate loads without external components while maintaining sub-μA quiescent operation.

FAQ
What is the operating temperature range for LMC7215QIM5X/NOPB?
The LMC7215QIM5X/NOPB is rated for −40°C to +85°C ambient operation. This range is validated per AEC-Q100 Grade 3 requirements and applies to both electrical performance and reliability metrics including propagation delay, input offset voltage, and latch-up immunity. The device maintains 0.7 μA typical supply current across this full range.
Does LMC7215QIM5X/NOPB support rail-to-rail input voltage beyond the supply rails?
Yes - the LMC7215QIM5X/NOPB features input common-mode voltage range from V− −0.2 V to V+ +0.3 V. This allows direct connection to V+ for supply monitoring or placement across high-side current-sense resistors without clamping diodes or attenuators. Input protection diodes conduct only when voltage exceeds these limits by >300 mV.
Can LMC7215QIM5X/NOPB drive an LED directly?
Yes - the LMC7215QIM5X/NOPB push-pull output can source up to 45 mA at 5 V supply, sufficient to drive standard 20 mA LEDs with appropriate series resistance. Unlike open-drain comparators, no external pull-up is required, simplifying layout and eliminating static current in the off state.
What is the maximum supply voltage for LMC7215QIM5X/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC7215QIM5X/NOPB is 10 V, but the recommended operating range is 2 V to 8 V. At 8 V, output drive remains functional, though thermal considerations require limiting continuous output current to avoid exceeding junction temperature limits in the SOT-23 package.
Is LMC7215QIM5X/NOPB pin-compatible with LMC7225QIM5X/NOPB?
Yes - LMC7215QIM5X/NOPB and LMC7225QIM5X/NOPB share identical 5-pin SOT-23 (DBV) package, pinout, and footprint. The only functional difference is output stage: LMC7215QIM5X/NOPB uses push-pull, while LMC7225QIM5X/NOPB uses open-drain. No PCB changes are required for substitution if external pull-up is acceptable.
