Product details
Overview
LPV7215MG/NOPB from Texas Instruments is a micropower, CMOS-input, rail-to-rail input/output (RRIO), push-pull output comparator optimized for ultra-low-power battery-operated systems. 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 use in precision window detectors and low-voltage IR receivers.
For engineers reviewing the LPV7215MG/NOPB datasheet, LPV7215MG/NOPB pinout, LPV7215MG/NOPB application, or LPV7215MG/NOPB equivalent, key selection criteria include its sub-1-µA quiescent current, rail-to-rail input common-mode range (−0.1 V to V+ + 0.1 V), push-pull output capable of ±17 mA drive, and guaranteed operation down to 1.8 V supply.
Technical Context
The LPV7215MG/NOPB employs a CMOS differential input stage with femtoampere-level input bias current (−40 fA typical), enabling high-impedance sensing without loading source circuits. Its rail-to-rail input common-mode range supports single-supply operation from 1.8 V to 5.5 V, with full functionality verified at 1.8 V, 2.7 V, and 5 V.
The device features a break-before-make MOS push-pull output stage that eliminates external pull-up resistors and minimizes shoot-through current. Propagation delay varies with overdrive (e.g., 4.5 µs at 100 mV, 13 µs at 10 mV) and supply voltage, while maintaining stable performance across temperature extremes (−40°C to 125°C).
Key Specifications

Applications
| RC Timers | Window Detectors |
|---|---|
Use Scenario: Generating precise time delays in low-power sleep-wake cycles using resistor-capacitor networks. IC Role / Device Role / Timing Role: Comparator acts as threshold detector triggering timer reset or state transition when capacitor voltage crosses reference. Use Value: Sub-1-µA quiescent current extends battery life; 4.5 µs propagation delay ensures timing accuracy within ±1% for 100-ms intervals. | Use Scenario: Monitoring sensor outputs (e.g., battery voltage, temperature) to detect out-of-range conditions. IC Role / Device Role / Timing Role: Dual-comparator configuration compares signal against upper/lower thresholds to assert fault flag.

Use Scenario: Demodulating pulsed infrared signals in remote-control receivers or proximity sensors. IC Role / Device Role / Timing Role: High-gain comparator converts weak AC-coupled IR photodiode signals into clean digital pulses. Use Value: 120 dB gain rejects ambient light noise; 100-fA input bias avoids signal attenuation in high-Z photodiode paths. | Use Scenario: Supervising critical system parameters (e.g., overtemperature, undervoltage) in medical or industrial equipment. IC Role / Device Role / Timing Role: Standby comparator continuously monitors analog inputs and asserts interrupt on violation. Use Value: −40°C to +125°C operation ensures reliability in harsh environments; 580 nA current enables always-on supervision. |
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), but no rail-to-rail input - limited to 0.2 V above GND and 0.2 V below V+. | Better for speed-critical, higher-supply designs; unsuitable for ground-sensing or low-VCM applications. | Select TLV7211IDBVR only when propagation delay <3 µs is required and input common-mode stays within restricted range. |
| MAX9060ASA+ | Lower supply current (350 nA), slower propagation (12 µs), rail-to-rail input, but only 1.8–5.5 V operation and −40°C to +85°C temp range. | Ideal for ultra-low-power, cost-sensitive consumer devices where extended temperature is not required. | Choose MAX9060ASA+ when minimizing current is paramount and industrial temperature range is unnecessary. |
Compared with TLV7211IDBVR and MAX9060ASA+, the LPV7215MG/NOPB uniquely combines rail-to-rail input, sub-600-nA supply current, and −40°C to +125°C operation - making it optimal for automotive, industrial, and long-life battery applications demanding both precision and ruggedness.

FAQ
What is the maximum supply voltage for LPV7215MG/NOPB?
The LPV7215MG/NOPB supports a maximum supply voltage of 5.5 V between V+ and V− terminals. Absolute maximum ratings specify 6 V, but recommended operating conditions limit continuous operation to 5.5 V to ensure reliability and parametric compliance across temperature. Exceeding 5.5 V may degrade long-term performance or trigger internal protection mechanisms.
Does LPV7215MG/NOPB support rail-to-rail input at 1.8 V supply?
Yes, LPV7215MG/NOPB supports rail-to-rail input common-mode voltage range from −0.1 V to V+ + 0.1 V at 1.8 V supply. Electrical characteristics confirm CMVR = −0.1 V to 1.9 V under 1.8 V operation, enabling direct interface with sensors or dividers operating near ground or supply rails without level-shifting circuitry.
What is the typical propagation delay of LPV7215MG/NOPB with 100-mV overdrive at 25°C?
The typical propagation delay of LPV7215MG/NOPB is 4.5 µs (high-to-low) and 6.6 µs (low-to-high) with 100-mV overdrive at 1.8 V supply and 25°C. These values are specified in Section 6.5 of the datasheet and represent factory-characterized typical performance under defined test conditions.
Can LPV7215MG/NOPB drive a 10-kΩ load directly?
Yes, LPV7215MG/NOPB can drive a 10-kΩ resistive load directly. At 5 V supply, its output can source up to 17 mA and sink up to 19 mA - sufficient to deliver >0.5 V swing across 10 kΩ. Output voltage swing data shows VO(H) ≥4.82 V and VO(L) ≤0.17 V at 1 mA, confirming robust drive capability for logic-level and moderate-current loads.
Is LPV7215MG/NOPB suitable for automotive applications?
Yes, LPV7215MG/NOPB is qualified for automotive applications per its −40°C to +125°C operating temperature range and AEC-Q200-relevant stress testing (including ±2000 V HBM ESD). While not AEC-Q100 certified, its thermal and electrical specifications meet requirements for cabin, body control, and non-safety-critical subsystems in passenger vehicles.
