Product details
Overview
LPV7215MG from Texas Instruments is a micropower, CMOS-input, rail-to-rail input/output (RRIO), push-pull output comparator optimized for 1.8-V single-supply operation. It delivers 580 nA supply current at 1.8 V, 4.5 µs propagation delay with 100-mV overdrive, and operates across −40°C to 125°C - enabling ultra-low-power sensing and threshold detection in battery-powered wearables and IoT sensor nodes.
For engineers reviewing the LPV7215MG datasheet, LPV7215MG pinout, LPV7215MG application, or LPV7215MG equivalent, this page provides verified functional identity, confirmed SOT-23-5/SC70-5 package mapping, validated push-pull output drive capability, temperature-stable offset voltage (±6 mV max), and real-world timing performance under 1.8–5.5 V supply conditions.
Technical Context
The LPV7215MG uses a CMOS input stage with rail-to-rail common-mode range (−0.1 V to V+ + 0.1 V) and zero differential input current (fA-level bias), enabling direct interface with high-impedance sources like thermistors and photodiodes. Its internal ESD diodes protect inputs up to ±2.5 V differential and ±0.3 V beyond rails.
The push-pull output stage eliminates external pull-up resistors and supports rail-to-rail swing: output low reaches 88 mV (at 500 µA sink, 25°C) and output high reaches 1.69 V (at 500 µA source, 1.8 V supply). Propagation delay varies with overdrive (4.5 µs at 100 mV, 13 µs at 10 mV) and supply voltage (7.7 µs H→L at 5 V, 13 µs at 1.8 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 580 nA typical at 1.8 V - enables >10-year battery life in coin-cell-powered monitoring circuits |
| Propagation Delay | 4.5 µs (H→L) / 6.6 µs (L→H) at 100-mV overdrive, 1.8 V - balances speed and power for RC timers and window detectors |

Pinout & Package
LPV7215MG is available in 5-pin SOT-23 (2.90 mm × 1.60 mm) and SC70 (2.00 mm × 1.25 mm) packages - both surface-mount, lead-free, RoHS-compliant, and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Push-pull output | Drives TTL/CMOS loads directly; no pull-up required; rail-to-rail swing (0.088 V to 1.69 V at 1.8 V) |
| 2 - V− | Negative supply | Ground reference (0 V); must be connected; not floating |
| 3 - VIN+ | Noninverting input | High-impedance CMOS node (fA bias); accepts signals from −0.1 V to V+ + 0.1 V |
| 4 - VIN− | Inverting input | Identical to VIN+; differential input voltage >0 required for stable comparison |
| 5 - V+ | Positive supply | 1.8–5.5 V operation; powers internal circuitry and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | Supports full supply-range signal monitoring without level-shifting - e.g., direct battery voltage tracking from 0 V to VCC |
| Push-pull output | Eliminates external pull-up resistor, reducing BOM count and PCB area while enabling bidirectional drive into capacitive loads |
| Ultra-low quiescent current | 580 nA at 1.8 V allows continuous operation on CR2032 (225 mAh) for >10 years in sleep-mode sensor wake-up circuits |
| High gain (120 dB) | Prevents metastability near threshold; <1 µV input change forces full rail-to-rail output transition - critical for noise-immune alarm triggers |
| Break-before-make output control | Minimizes shoot-through current during output transitions - preserves efficiency and thermal stability in high-duty-cycle applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDBVR | Higher supply current (1.1 µA), faster propagation (2.5 µs), open-drain output only | Requires external pull-up; unsuitable where rail-to-rail sourcing or low-noise push-pull drive is needed | Choose TLV7211IDBVR only when speed >2 µs is mandatory and open-drain interface is acceptable |
| LMV7215M5X | Same pinout, identical specs, but obsolete per TI PDN (2021); last-time-buy status | No functional difference; not recommended for new designs due to discontinuation risk | Select LPV7215MG for long-term supply continuity and active production support |
Compared with TLV7211IDBVR and LMV7215M5X, the LPV7215MG uniquely combines ultra-low 580 nA supply current, push-pull output, and guaranteed −40°C to 125°C operation - making it the only option for space-constrained, battery-powered systems requiring both minimal power and direct logic-compatible drive.

FAQ
What is the maximum operating supply voltage for the LPV7215MG?
The LPV7215MG supports a supply voltage range of 1.8 V to 5.5 V. Absolute maximum rating is 6 V across V+ and V− terminals. Operation above 5.5 V risks permanent damage and violates recommended conditions - always limit V+ to ≤5.5 V relative to V− in LPV7215MG designs.
Does the LPV7215MG require external hysteresis for stable operation?
Yes - the LPV7215MG has no internal hysteresis. Its high gain (120 dB) makes it susceptible to oscillation near input threshold crossings. For stable switching in noisy environments, add 1–10 mV of positive feedback via resistor network between VOUT and VIN+. This is explicitly recommended in the LPV7215MG datasheet Section 8.1.
Can the LPV7215MG drive a 10-kΩ load directly at 1.8 V supply?
Yes. At 1.8 V, the LPV7215MG output high reaches 1.69 V (500 µA source, 25°C) and output low drops to 180 mV (1 mA sink, 25°C). Driving a 10-kΩ load draws only 180 µA, well within its 2.26 mA sourcing and 3.1 mA sinking capability - ensuring full rail-to-rail swing without degradation in LPV7215MG performance.
Is the LPV7215MG pin-compatible with other comparators in TI's LPV7xxx family?
No. The LPV7215MG uses a unique 5-pin SOT-23/SC70 pinout (VOUT, V−, VIN+, VIN−, V+). LPV7211 and LPV7231 share the same footprint but differ in output type (open-drain vs push-pull) and electrical specs - direct substitution without circuit review is not supported for LPV7215MG.
What is the input bias current specification for the LPV7215MG at 25°C?
The LPV7215MG exhibits input bias current of −40 fA (typical) at 25°C, measured at VCM = 1.6 V (1.8 V supply). This fA-level leakage enables use with megaohm-scale sensor interfaces - such as thermistor dividers or photodiode transimpedance amplifiers - without measurable voltage error in LPV7215MG-based circuits.
