Product details
Overview
LMC7215IM5/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 ultra-low-power battery monitoring in portable instrumentation.
For engineers reviewing the LMC7215IM5/NOPB datasheet, LMC7215IM5/NOPB pinout, LMC7215IM5/NOPB application, or LMC7215IM5/NOPB equivalent, this device is selected for single-supply precision threshold detection where minimal quiescent current, rail-to-rail input, and direct load driving without pull-up resistors are critical design requirements.
Technical Context
The LMC7215IM5/NOPB employs a CMOS input stage with <5 fA input bias current and >80 dB CMRR, enabling high-impedance sensing without matching networks. Its push-pull output eliminates external pull-up components and supports sourcing up to 50 mA at 5 V while maintaining sub-1 μA quiescent draw.
It operates across −40°C to +85°C with guaranteed functionality from 2.7 V to 5 V, and its input common-mode range extends to V− −0.2 V and V+ +0.3 V-critical for supply rail monitoring and current-sense amplifier interfaces in low-voltage systems.
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 direct connection to Li-ion, alkaline, and 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-shunt voltages exceeding rail limits. |
| Output Drive (Sourcing) | 45 mA at 5 V - drives LEDs, relays, or logic inputs directly without buffer stages. |
| Propagation Delay | 25 μs @ 10 mV overdrive, 5 V - balances speed and power for RC timer, window comparator, and alarm trigger applications. |
| Input Offset Voltage | 6 mV max - ensures reliable 10–20 mV threshold detection in precision battery undervoltage lockout. |
| Latch-up Immunity | >300 mA - withstands transient ESD and I/O fault currents without destructive latch-up. |
Pinout & Package
LMC7215IM5/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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Push-pull output | Active-high/low digital output capable of sourcing/sinking ≥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 | High-impedance CMOS node; symmetric with −IN for differential threshold setting. |
| 5 (V+) | Positive supply | Accepts 2 V–8 V; powers internal circuitry and defines output high-level voltage. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701IDBVR | Higher supply current (1.6 μA typ), rail-to-rail input only (not beyond-rail), open-drain output. | Requires external pull-up; unsuitable for direct LED driving or rail-exceeding input sensing. | Select TLV3701IDBVR only if open-drain interface or higher speed (1.2 μs propagation) is prioritized over ultra-low power and beyond-rail input. |
| MAX9021AXK+T | Lower supply current (350 nA typ), but limited 1.8 V–5.5 V supply range and no beyond-rail input capability. | Cannot monitor 8 V supplies or sense above V+; requires level-shifting for high-side current sensing. | Choose MAX9021AXK+T only for sub-1 V battery systems where 350 nA quiescent is mandatory and input range stays within rails. |
Compared with TLV3701IDBVR and MAX9021AXK+T, LMC7215IM5/NOPB uniquely combines beyond-rail input, push-pull output, and sub-1 μA supply current-making it the sole option for direct high-side sensing and load-driving in 2–8 V battery-powered systems.

FAQ
What is the maximum supply voltage rating for LMC7215IM5/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMC7215IM5/NOPB is 10 V, with recommended operating range from 2 V to 8 V. Exceeding 10 V risks permanent damage per Absolute Maximum Ratings. The device is fully specified and functional across 2.7 V to 5 V, making it ideal for standard Li-ion and regulated 3.3 V systems. LMC7215IM5/NOPB maintains rail-to-rail input performance and sub-1 μA quiescent current within this validated range.
Does LMC7215IM5/NOPB support input voltages beyond the supply rails?
Yes, LMC7215IM5/NOPB supports input common-mode voltage from V− −0.2 V to V+ +0.3 V, verified per Electrical Characteristics tables. This beyond-rail capability enables direct connection to battery terminals or high-side current-sense resistors without external clamping. LMC7215IM5/NOPB input protection diodes conduct only when input exceeds rails by >300 mV, limiting current to <5 mA with proper series resistance-ensuring safe operation in overvoltage sensing applications.
Can LMC7215IM5/NOPB drive an LED directly?
Yes, LMC7215IM5/NOPB can drive standard 20 mA LEDs directly via its push-pull output, sourcing up to 45 mA at 5 V supply. No external transistor or pull-up resistor is needed. For red/green LEDs with ~1.8–2.2 V forward voltage, connect anode to V+ and cathode to LMC7215IM5/NOPB OUT (Pin 1); output goes low to illuminate. LMC7215IM5/NOPB thermal performance in SOT-23 remains safe under continuous 20 mA load at ambient ≤60°C.
What is the propagation delay of LMC7215IM5/NOPB at 2.7 V supply?
At 2.7 V supply and 10 mV input overdrive, LMC7215IM5/NOPB exhibits 17 μs propagation delay (tPHL and tPLH), as specified in AC Electrical Characteristics. This value increases slightly at lower overdrive levels but remains below 200 μs even with 1 mV overdrive. LMC7215IM5/NOPB delay is supply-voltage dependent due to internal CMOS gate thresholds-designers should reference Figure 4 (Prop Delay vs. Supply Voltage) in the datasheet for exact timing across 2.7 V–5 V operation.
Is LMC7215IM5/NOPB qualified for automotive applications?
No, LMC7215IM5/NOPB is the commercial-grade catalog version. For automotive use, TI offers LMC7215QIM5/NOPB-a variant qualified to AEC-Q100 Grade 3 (−40°C to +85°C) with enhanced process controls and lot traceability. LMC7215IM5/NOPB operates across the same temperature range but lacks automotive qualification testing and documentation. Select LMC7215QIM5/NOPB for infotainment, body control, or ADAS subsystems requiring automotive reliability assurance.
