Product details
Overview
LMC7215QIM5/NOPB from Texas Instruments is an ultra-low-power, rail-to-rail input CMOS comparator with push-pull output, designed for battery-powered systems. It delivers 0.7 μA typical supply current, operates from 2V to 8V, supports input common-mode voltage beyond rails (−0.3 V to 5.3 V at VS = 5 V), provides 45 mA output drive, and achieves 25 μs propagation delay at 10 mV overdrive - enabling precision threshold detection in handheld meters and automotive monitoring circuits.
For engineers reviewing the LMC7215QIM5/NOPB datasheet, LMC7215QIM5/NOPB pinout, LMC7215QIM5/NOPB application, or LMC7215QIM5/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 3 qualification, rail-to-rail input range exceeding supply rails, push-pull output eliminating external pull-up resistors, sub-1 μA quiescent current, and verified operation across −40°C to +85°C industrial/automotive temperature range.
Technical Context
The LMC7215QIM5/NOPB implements a high-gain CMOS comparator core (140 dB voltage gain) with rail-to-rail input stage featuring diode-clamped inputs that tolerate voltages up to ±0.3 V beyond V+ and V−. Its push-pull output stage uses complementary NMOS/PMOS drivers to deliver both sourcing (up to 50 mA at 5 V) and sinking (≥20 mA) capability without external components.
This architecture enables direct LED/beeper driving, eliminates shoot-through current during low-to-high transitions (only present <400 ns on high-to-low edges), and maintains latch-up immunity >300 mA - critical for robust operation in noisy automotive and portable metering environments where supply transients and ESD events are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 0.7 μA typical - enables multi-year battery life in always-on sensing nodes. |
| Supply Voltage Range | 2 V to 8 V - supports single-cell Li-ion, dual-cell alkaline, and 5 V/3.3 V system rails. |
| Input Common-Mode Range | −0.3 V to 5.3 V at VS = 5 V - allows direct sensing of VCC or ground-referenced currents without level-shifting. |
| Propagation Delay | 24 μs at 10 mV overdrive (VS = 5 V) - suitable for RC timers and slow-varying alarm thresholds. |
| Output Drive Capability | 45 mA sourcing / ≥20 mA sinking at VS = 5 V - drives LEDs, relays, or logic inputs directly. |
| Input Offset Voltage | 6 mV max - ensures reliable detection of ≥10 mV signal differentials in precision comparators. |
| Latch-up Immunity | >300 mA - withstands transient fault currents without destructive latch-up. |
Pinout & Package
LMC7215QIM5/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 PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Non-inverting input | Rail-to-rail capable; accepts signals from −0.3 V to VS + 0.3 V - enables direct high-side or low-side current sensing. |
| 2 - IN− | Inverting input | Identical rail-to-rail range as IN+; differential input tolerance ±0.3 V beyond supplies prevents damage from overvoltage transients. |
| 3 - GND | Ground reference | Return path for supply and output current; must be low-impedance to maintain noise immunity in automotive environments. |
| 4 - VS | Positive supply | Accepts 2 V–8 V; internal regulation ensures stable biasing across full voltage range - no external decoupling required for basic operation. |
| 5 - OUT | Push-pull output | Active-high and active-low drive; eliminates need for pull-up resistor - reduces BOM count and power loss in battery systems. |
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 |
|---|---|---|---|
| LMC7225IM5/NOPB | Open-drain output; requires external pull-up; identical supply current and input specs. | Suitable only where level shifting (e.g., 3.3 V logic to 5 V bus) or wired-OR functionality is needed. | Select LMC7225IM5/NOPB only if open-drain behavior is explicitly required; otherwise LMC7215QIM5/NOPB offers lower system power and simpler layout. |
| TLV7211QDBVRQ1 | Higher speed (1.8 μs propagation delay), higher supply current (17 μA), same AEC-Q100 Grade 3 rating. | Better suited for fast-response safety-critical alerts (e.g., airbag deployment triggers) but increases battery load. | Choose TLV7211QDBVRQ1 when microsecond response is mandatory; retain LMC7215QIM5/NOPB for ultra-low-power, millisecond-scale monitoring. |
Compared with LMC7225IM5/NOPB, LMC7215QIM5/NOPB eliminates external pull-up resistors and reduces standby power by 96%; versus TLV7211QDBVRQ1, it trades 70× slower response for 24× lower quiescent current - making it optimal for energy-constrained automotive subsystems where timing margins exceed 20 μs.

FAQ
What is the operating temperature range for LMC7215QIM5/NOPB?
The LMC7215QIM5/NOPB is qualified for −40°C to +85°C ambient operation per AEC-Q100 Grade 3 requirements. This range is validated across all electrical parameters including input offset voltage, propagation delay, and output drive strength - ensuring reliable performance in under-hood automotive locations and industrial field-deployed meters.
Does LMC7215QIM5/NOPB require external pull-up resistors on its output?
No. The LMC7215QIM5/NOPB features a true push-pull output stage capable of both sourcing and sinking current. Unlike open-drain comparators, it drives high and low actively - eliminating the need for external pull-up resistors and reducing total system power consumption in battery-powered designs.
How does the input common-mode range of LMC7215QIM5/NOPB exceed the supply rails?
The LMC7215QIM5/NOPB input stage incorporates ESD protection diodes that allow input voltages up to 0.3 V beyond VS and GND. At VS = 5 V, this enables a −0.3 V to 5.3 V common-mode range - permitting direct connection to battery terminals or supply rails for current/voltage monitoring without attenuators or level shifters.
Is LMC7215QIM5/NOPB pin-compatible with LMC7225 variants?
Yes - LMC7215QIM5/NOPB and LMC7225 variants share identical 5-pin SOT-23 (DBV) packaging and pinout (IN+, IN−, GND, VS, OUT). However, LMC7225 has open-drain output, so substituting it for LMC7215QIM5/NOPB requires adding a pull-up resistor and verifying logic-level compatibility.
What is the maximum output short-circuit current for LMC7215QIM5/NOPB at 5 V supply?
At VS = 5 V, the LMC7215QIM5/NOPB can source up to 50 mA and sink over 20 mA continuously. Short-circuit current measurements show 50 mA sourcing capability - sufficient to drive standard LEDs or small relays directly without external buffering, though thermal limits must be observed in sustained fault conditions.
