Product details
Overview
LMC7215IM5X/NOPB 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 use in battery-powered voltage monitoring and low-power threshold detection circuits.
For engineers reviewing the LMC7215IM5X/NOPB datasheet, LMC7215IM5X/NOPB pinout, LMC7215IM5X/NOPB application, or LMC7215IM5X/NOPB equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative comparators for ultra-low-power single-supply designs.
Technical Context
The LMC7215IM5X/NOPB implements a high-gain CMOS comparator core (140 dB voltage gain) with rail-to-rail input stage capable of accepting signals up to 0.3 V beyond V+ and V−. Its push-pull output eliminates external pull-up resistors, reducing system power and simplifying interface to logic or discrete loads.
It operates across −40°C to +85°C with guaranteed performance from 2.7 V to 5 V, supports capacitive loads up to 10,000 pF with minimal transition slowdown, and exhibits latch-up resistance exceeding 300 mA - critical for robustness in portable and industrial sensing nodes.
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 direct connection to Li-ion, alkaline, or regulated 3.3 V/5 V rails without level-shifting |
| Input Common-Mode Range | V− −0.2 V to V+ +0.3 V - allows direct sensing of supply voltage or current-sense resistor voltages above/below rails |
| Propagation Delay | 25 μs @ 10 mV overdrive, 5 V supply - suitable for RC timers, window comparators, and slow-response alarm triggers |
| Output Drive Capability | 45 mA sink/source @ 5 V - drives LEDs, small relays, or logic inputs directly without buffer stages |
| Input Offset Voltage | 6 mV max - ensures reliable detection of ≥10 mV thresholds in precision battery voltage monitors |
| CMRR | 80 dB min - maintains accuracy in noisy environments where supply ripple couples into reference paths |
Pinout & Package
LMC7215IM5X/NOPB 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 PCBs and compatible with standard reflow profiles (MSL Level-1, 260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Push-pull output | Active-high/low digital output; no external pull-up required; sinks or sources load current directly |
| 2 (−IN) | Inverting input | Differential input node; accepts voltages from V− −0.2 V to V+ +0.3 V; <5 fA bias current |
| 3 (GND) | Ground reference | Power return path and signal reference; must be low-impedance for stable rail-to-rail operation |
| 4 (+IN) | Non-inverting input | Differential input node; identical common-mode range and bias current as −IN |
| 5 (V+) | Positive supply | Single-supply rail; supports 2 V–8 V; internal regulation not required; bypass capacitor recommended |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with beyond-rail range | Accepts inputs up to 0.3 V above V+ or 0.2 V below GND - enables direct high-side supply monitoring without attenuators |
| Push-pull output stage | Eliminates need for external pull-up resistors - reduces BOM count, board area, and standby power in always-on systems |
| Ultra-low 0.7 μA supply current | Extends battery life in handheld meters and IoT sensors where quiescent current dominates lifetime energy budget |
| High output current drive (45 mA) | Directly interfaces to LEDs, piezo buzzers, or MOSFET gates - avoids added driver ICs in simple alert circuits |
| Latch-up immunity >300 mA | Withstands transient overcurrent events during ESD or hot-plug - improves field reliability in unregulated environments |
Applications
| Battery Voltage Monitor | RC Timer Circuit |
|---|---|
Use Scenario: Detecting low-battery condition in a medical wearable before shutdown. IC Role / Device Role / Timing Role: Threshold comparator comparing battery voltage against a precision reference. Use Value: 0.7 μA supply current minimizes self-discharge; rail-to-rail input allows direct measurement of 2.0–3.6 V LiPo cells. |
Use Scenario: Generating precise time delays in a smoke detector's self-test sequence. IC Role / Device Role / Timing Role: Core timing element in an astable multivibrator using R-C network. Use Value: Low input bias current (<5 fA) prevents capacitor leakage errors; 25 μs propagation delay ensures predictable timing at sub-10 Hz frequencies. |

Use Value: Input tolerates ±5 kV transient via series resistor (per TI app note); 0.2 V input offset ensures clean trip at 100 mV thresholds. |
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 |
|---|---|---|---|
| TLV3691IDBVR | 0.5 μA supply current, 1.8 V–5.5 V supply, open-drain output only | Requires external pull-up; better for level-shifting but less efficient for direct load driving | Select TLV3691IDBVR when interfacing to 1.8 V logic or needing higher-speed response (10 μs propagation) |
| MAX9021AXK+T | 1.1 μA supply current, 1.6 V–5.5 V supply, push-pull output, 12-bit internal reference | Includes integrated reference; larger 5-pin SC70 package (2.0 mm × 1.25 mm) | Select MAX9021AXK+T when reference stability is critical and board space permits slightly larger footprint |
Compared with LMC7215IM5X/NOPB, TLV3691IDBVR offers lower quiescent current but lacks push-pull drive, while MAX9021AXK+T adds reference integration at higher supply current - making LMC7215IM5X/NOPB optimal for cost-sensitive, space-constrained, single-supply systems requiring direct load control.

FAQ
What is the maximum supply voltage for LMC7215IM5X/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMC7215IM5X/NOPB is 10 V, but the recommended operating range is 2 V to 8 V per the datasheet. Operation at 8 V is fully characterized and supported across the full −40°C to +85°C temperature range, with parameters such as propagation delay and output drive validated at 5 V and 2.7 V.
Does LMC7215IM5X/NOPB have rail-to-rail input capability?
Yes, LMC7215IM5X/NOPB features true rail-to-rail input with common-mode voltage range extending 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 exceeding the supply, such as high-side current sense nodes or unregulated battery terminals, without attenuation or level shifting.
Can LMC7215IM5X/NOPB drive an LED directly?
Yes, LMC7215IM5X/NOPB can drive an LED directly: its push-pull output delivers up to 45 mA sink/source current at 5 V supply, sufficient for standard indicator LEDs (typically 2–20 mA). A series current-limiting resistor is still required; for example, a 220 Ω resistor limits current to ~14 mA at 5 V with a 2 V LED forward drop.
What is the propagation delay of LMC7215IM5X/NOPB under typical conditions?
LMC7215IM5X/NOPB has a typical propagation delay of 25 μs when driven with 10 mV overdrive at 5 V supply and 25°C. Delay decreases to 12 μs at 100 mV overdrive and increases to 17 μs at 2.7 V supply with 10 mV overdrive - all values specified in the AC Electrical Characteristics table of the official datasheet.
Is LMC7215IM5X/NOPB pin-compatible with LMC7225IM5X/NOPB?
No, LMC7215IM5X/NOPB is not pin-compatible with LMC7225IM5X/NOPB despite sharing the same SOT-23-5 package. LMC7215IM5X/NOPB has a push-pull output (pin 1 = OUT), while LMC7225IM5X/NOPB has an open-drain output (pin 1 = OD OUT) requiring an external pull-up. Swapping them requires PCB layout changes and circuit validation.
