Product details
Overview
LMV7275IDCKRQ1 from Texas Instruments is an automotive-grade single rail-to-rail input comparator with open-drain output, designed for low-voltage (1.8 V to 5.5 V), ultra-low-power systems. It delivers 880 ns propagation delay at 1.8 V, 9 µA supply current per channel, and ±4 mV input offset voltage - enabling precise threshold detection in battery-powered sensing and power monitoring circuits.
For engineers reviewing the LMV7275IDCKRQ1 datasheet, LMV7275IDCKRQ1 pinout, LMV7275IDCKRQ1 application, or LMV7275IDCKRQ1 equivalent, key selection considerations include its AEC-Q100 Grade 3 qualification (-40°C to 85°C), SC-70 (5-pin) package footprint, rail-to-rail input range extending 0.1 V beyond rails, and open-drain output supporting level-shifting up to 5.5 V independent of supply.
Technical Context
The LMV7275IDCKRQ1 uses a paralleled PNP/NPN input stage to achieve a −0.1 V to VS + 0.1 V common-mode input range, with crossover near 950 mV below VS. Its bipolar input transistors provide low noise and 10 nA input bias current, while CMOS output enables minimal negative swing and compatibility with wired-OR configurations.
Propagation delay varies with supply voltage and overdrive: 880 ns (tPHL) at 1.8 V/20 mV overdrive, increasing to 2100 ns at 5 V/20 mV overdrive. The open-drain output requires external pull-up and supports level-shifting - e.g., 1.8-V comparator driving 3.3-V logic - without additional interface circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct operation from Li-ion cell, 3.3-V, or 5-V rails without regulation. |
| Supply Current (TYP) | 9 µA at 1.8 V - enables multi-year battery life in always-on wake-up or sensor monitoring circuits. |
| Propagation Delay (tPHL) | 880 ns at 1.8 V, 20 mV overdrive - sufficient for sub-MHz window comparators and power-good sequencing. |
| Input Offset Voltage (MAX) | 4 mV - ensures reliable 10-mV-level threshold detection across temperature without trimming. |
| Input Common-Mode Range | −0.1 V to VS + 0.1 V - allows direct sensing of signals at ground or near supply rails (e.g., battery voltage monitoring). |
| Output Type | Open-drain - enables level-shifting, wired-OR bus sharing, and pull-up to any voltage ≤ 5.5 V. |
| ESD Rating (HBM) | ±2000 V - meets AEC-Q100 stress requirements for automotive PCB handling and assembly. |
Pinout & Package
LMV7275IDCKRQ1 is housed in a 5-pin SC-70 package (1.25 mm × 2.00 mm), optimized for space-constrained automotive and portable electronics layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Non-inverting input | Accepts analog signals from −0.1 V to VS + 0.1 V; used for threshold comparison against reference or IN−. |
| 2 - V− | Negative supply | Ground or negative rail connection; defines lower bound of input common-mode and output swing. |
| 3 - IN− | Inverting input | Reference input node; supports hysteresis feedback or fixed-voltage threshold setting. |
| 4 - OUT | Open-drain output | Drains current when active; requires external pull-up resistor to define logic-high level and enable level-shifting. |
| 5 - V+ | Positive supply | Primary power connection (1.8–5.5 V); supplies internal bias and defines upper rail for input/output operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with extended range | Operates with inputs 0.1 V below V− and 0.1 V above V+, enabling direct battery voltage or ground-referenced signal monitoring. |
| Ultra-low quiescent current | 9 µA typical at 1.8 V - reduces system standby power in automotive body controllers and IoT sensors. |
| AEC-Q100 Grade 3 qualification | Validated for −40°C to +85°C ambient operation, HBM ±2 kV, CDM ±1 kV - suitable for under-hood and cabin modules. |
| Open-drain output with level-shift capability | Output can be pulled up to 5.5 V regardless of V+ (e.g., 1.8-V comparator driving 3.3-V MCU interrupt line). |
| Low input bias current | 10 nA maximum - minimizes loading error on high-impedance sources like thermistor dividers or capacitive sensors. |
Applications
| Power Supply Monitoring | Battery Voltage Threshold Detection |
|---|---|
|
Use Scenario: Monitoring 12-V automotive battery via resistive divider to detect undervoltage (e.g., <11.5 V) and overvoltage (e.g., >14.8 V) conditions. IC Role / Device Role / Timing Role: Single comparator configured as window detector using dual thresholds; open-drain output drives MCU reset or warning LED. Use Value: Rail-to-rail input captures full divider range down to 0 V; 9 µA supply current avoids loading sensitive divider network. |
Use Scenario: Detecting end-of-charge or deep-discharge in Li-ion wearable devices using a 3.3-V supply rail. IC Role / Device Role / Timing Role: Threshold detector comparing battery voltage (scaled) against internal reference; triggers low-battery interrupt. Use Value: 4 mV max VOS ensures consistent 3.0-V cutoff across temperature; SC-70 footprint fits compact wearables. |
| Level-Shifting Interface | Wired-OR Fault Bus |
|
Use Scenario: Converting 1.8-V sensor alert signal to 3.3-V logic level for host microcontroller input. IC Role / Device Role / Timing Role: Comparator output pulled up to 3.3 V while powered from 1.8 V - no level translator IC required. Use Value: Open-drain architecture eliminates need for bidirectional translators; 880 ns delay preserves timing integrity in fast alerts. |
Use Scenario: Aggregating fault signals from multiple subsystems (e.g., motor drivers, lighting modules) onto shared diagnostic bus. IC Role / Device Role / Timing Role: Each LMV7275IDCKRQ1 drives same pull-up resistor; any fault pulls bus low (wired-OR logic). Use Value: Guaranteed 4 mA sink capability ensures robust low-state drive; AEC-Q100 qualification ensures reliability in safety-critical paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211QDBVRQ1 | Higher supply current (25 µA), faster propagation (50 ns at 5 V), but only 2.7–5.5 V supply range - no 1.8-V operation. | Not suitable for 1.8-V battery-powered systems; better for higher-speed 3.3/5-V industrial controls. | Select TLV7211QDBVRQ1 only if speed >500 ns and supply ≥2.7 V are guaranteed; LMV7275IDCKRQ1 remains optimal for ultra-low-power 1.8-V designs. |
| LMV7272IDGKRQ1 | Dual-channel version in same SC-70-8 package; identical electrical specs per channel but double supply current (18 µA). | Used where two independent thresholds are needed (e.g., over/under voltage), not single-function monitoring. | Choose LMV7272IDGKRQ1 when dual comparators reduce board area vs. two singles; otherwise LMV7275IDCKRQ1 offers lowest per-channel power. |
Compared with TLV7211QDBVRQ1 and LMV7272IDGKRQ1, LMV7275IDCKRQ1 uniquely balances 1.8-V operation, 9 µA supply current, and AEC-Q100 Grade 3 qualification - making it the only choice for space- and power-constrained automotive sensors requiring rail-to-rail input at minimum voltage.

FAQ
What is the minimum operating supply voltage for LMV7275IDCKRQ1?
The LMV7275IDCKRQ1 is fully specified down to 1.8 V supply voltage, with key parameters - including 9 µA supply current, 880 ns propagation delay, and rail-to-rail input operation - guaranteed at this voltage. Operation below 1.8 V is not characterized or recommended per the datasheet.
Does LMV7275IDCKRQ1 support true rail-to-rail input?
Yes, LMV7275IDCKRQ1 supports input voltages from −0.1 V below V− to 0.1 V above V+, verified across temperature and supply conditions. This extended range enables direct measurement of signals at ground or near supply rails - critical for accurate battery voltage and power-supply monitoring applications.
Can LMV7275IDCKRQ1 output drive a 3.3-V logic input while powered from 1.8 V?
Yes. LMV7275IDCKRQ1 features an open-drain output that can be pulled up to any voltage up to 5.5 V, independent of its 1.8-V supply. When used with a 3.3-V pull-up resistor, it reliably generates 3.3-V logic-high levels - eliminating the need for external level-shifting components.
