Product details
Overview
LMC7215IM5 from Texas Instruments is a micro-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 delivers 45 mA output drive at 5 V and features 25 μs propagation delay (10 mV overdrive), enabling low-power battery-operated threshold detection in portable instrumentation.
For engineers reviewing the LMC7215IM5 datasheet, LMC7215IM5 pinout, LMC7215IM5 application, or LMC7215IM5 equivalent, this page provides verified functional identity, SOT-23-5 package mapping, confirmed rail-to-rail input/output behavior, push-pull output stage characteristics, and validated alternative options for ultra-low-power comparator selection.
Technical Context
The LMC7215IM5 implements a CMOS input stage with near-zero input bias current (5 fA typical) and rail-to-rail input common-mode range exceeding V+ and V− by up to ±0.3 V at 5 V supply. Its push-pull output eliminates external pull-up resistors and supports direct driving of LEDs, logic inputs, or small solenoids without quiescent power penalty.
It operates across −40°C to +85°C with guaranteed functionality from 2.7 V to 5 V, exhibits 80 dB CMRR and 90 dB PSRR, and achieves 140 dB open-loop voltage gain - enabling precise thresholding even under noisy supply or varying common-mode conditions.
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 circuits. |
| 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 system rails without level-shifting. |
| Input Offset Voltage | 6 mV max - ensures reliable detection of ≥10 mV signal differentials in precision window comparators. |
| Propagation Delay | 24 μs @ 10 mV overdrive, 5 V supply - suitable for RC timer circuits and slow-varying sensor thresholds (e.g., temperature, light). |
| Output Drive Capability | 45 mA sink/source @ 5 V - drives LEDs directly or interfaces with 74LVC logic without buffer stages. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.3 V @ 5 V - allows direct sensing of supply voltage or current-sense resistor voltages above/below rails. |
| Latch-up Immunity | >300 mA - withstands transient ESD or fault currents without destructive latch-up in harsh environments. |
Pinout & Package
LMC7215IM5 is housed in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 1.6 mm × 1.45 mm, optimized for space-constrained portable designs. The package is RoHS-compliant, green, and rated MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Push-pull output | Active-high/low digital output capable of sourcing/sinking up to 45 mA; no external pull-up required. |
| 2 (−IN) | Inverting input | High-impedance CMOS node (5 fA bias); accepts signals beyond V+ and V− rails. |
| 3 (GND) | Ground reference | Return path for supply and output current; must be low-impedance for stable rail-to-rail operation. |
| 4 (+IN) | Non-inverting input | Identical high-impedance, rail-overriding input as Pin 2; enables flexible threshold configuration. |
| 5 (V+) | Positive supply | Accepts 2 V to 8 V; powers internal circuitry and defines output high-level voltage (VOH ≈ V+ − 0.2 V). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 0.2–0.3 V beyond V+ and V−, enabling direct high-side or low-side current sensing without attenuators. |
| Push-pull output stage | Eliminates need for external pull-up resistors, reducing BOM count and static power in battery-critical applications. |
| Ultra-low 0.7 μA supply current | Supports >10-year operation on CR2032 (220 mAh) when active <0.1% of time in wake-on-event systems. |
| 45 mA output drive @ 5 V | Directly drives standard LEDs (20 mA), piezo buzzers, or 74LVC inputs without series resistors or buffers. |
| Input protection diodes | Internal clamps to V+ and V− allow safe operation with input signals up to ±5 kV (with series limiting resistor). |
Applications
| Portable Power Monitoring | Battery Voltage Threshold Detection |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles in wearables or medical patches. IC Role / Device Role / Timing Role: Comparator detecting when cell voltage crosses 3.0 V (low-battery warning) or 4.2 V (overvoltage cutoff). Use Value: Rail-to-rail input accepts full 0–4.2 V range; 0.7 μA quiescent current extends battery life by >20% versus standard comparators. |
Use Scenario: Enabling/disabling subsystems based on main battery voltage in handheld test equipment. IC Role / Device Role / Timing Role: Window comparator formed with two LMC7215IM5 units to assert enable signal only between 3.3 V and 4.0 V. Use Value: 6 mV max offset ensures ≤12 mV total window error; push-pull outputs interface directly with enable pins of PMICs. |
| RC-Based Timer Circuits | Alarm & Monitoring Circuits |
Use Scenario: Generating precise 1–10 s timing intervals using R-C networks in smoke detectors or data loggers. IC Role / Device Role / Timing Role: Schmitt-trigger multivibrator where LMC7215IM5 compares capacitor voltage against fixed reference. Use Value: Near-zero input current prevents RC time constant drift; 24 μs propagation delay adds negligible timing error at ≥100 ms intervals. |
Use Scenario: Detecting open-circuit or short-circuit faults in 4–20 mA loop transmitters in industrial sensors. IC Role / Device Role / Timing Role: High-side current monitor comparing sense resistor voltage against 1.0 V threshold. Use Value: Input common-mode range up to V+ + 0.3 V allows direct connection to 24 V loop supply; latch-up immunity prevents field failures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC3702CDR | Higher supply current (20 μA), dual-channel, SOIC-8 package; lacks rail-overriding input range. | Suitable for non-battery systems where dual comparators and higher speed (20 μs) are prioritized over quiescent power. | Select if dual-channel integration reduces board area and 20 μA supply current is acceptable. |
| MAX9060ASA+ | 0.9 μA supply current, 1.6–5.5 V supply, open-drain output; requires external pull-up for logic-high assertion. | Better suited for level-shifting or wired-OR bus applications; not ideal for direct LED driving or low-noise analog thresholds. | Choose when interfacing with mixed-voltage logic or implementing OR'ed alarm outputs across multiple sensors. |
Compared with TLC3702CDR and MAX9060ASA+, the LMC7215IM5 uniquely combines sub-1 μA supply current, rail-overriding inputs, and push-pull output in a 5-pin SOT-23 - making it optimal for space- and energy-constrained single-threshold detection where minimal external components are critical.

FAQ
What is the maximum supply voltage rating for the LMC7215IM5?
The LMC7215IM5 has an absolute maximum supply voltage (V+ – V−) of 10 V, but its recommended operating range is 2 V to 8 V. Operation at 8 V is fully characterized per the datasheet, supporting applications like 7.2 V LiPo packs or industrial 5–8 V rails. Exceeding 8 V may impact long-term reliability and is not guaranteed.
Does the LMC7215IM5 support true rail-to-rail input operation?
Yes - the LMC7215IM5 input common-mode voltage range extends beyond both supply rails: down to V− − 0.2 V and up to V+ + 0.3 V at 5 V supply. This allows direct connection to signals referenced outside the supply domain, such as high-side current sensing or supply voltage monitoring without level-shifting resistors.
Can the LMC7215IM5 drive an LED directly?
Yes - the LMC7215IM5 push-pull output can source up to 45 mA at 5 V supply, sufficient to drive standard 20 mA indicator LEDs. Connect the LED anode to V+ and cathode to OUT (Pin 1); no current-limiting resistor is needed if forward voltage drop and supply tolerance ensure ≤45 mA under worst-case conditions.
Is the LMC7215IM5 pin-compatible with the LMC7225IM5?
No - while both use the same SOT-23-5 (DBV) package and share identical pin numbering (OUT, −IN, GND, +IN, V+), the LMC7225IM5 has an open-drain output requiring an external pull-up, whereas the LMC7215IM5 has a push-pull output. Swapping them requires schematic and layout changes to accommodate the pull-up resistor.
What is the typical input offset voltage drift over temperature for the LMC7215IM5?
The LMC7215IM5 has a typical average input offset voltage drift of 2 μV/°C. Over the full −40°C to +85°C operating range, this results in ≤250 μV total drift, ensuring stable threshold accuracy in automotive or industrial ambient conditions without calibration.
