Product details
Overview
TLV7041DPWR from Texas Instruments is a single-channel, nanopower, open-drain comparator optimized for ultra-low-power sensing and voltage monitoring in battery-powered systems. It operates from 1.6V to 6.5V, draws only 315nA quiescent current, delivers 3µs propagation delay, features rail-to-rail input common-mode range, and includes internal hysteresis - enabling reliable threshold detection in gas meters and smoke detectors.
For engineers reviewing the TLV7041DPWR datasheet, TLV7041DPWR pinout, TLV7041DPWR application, or TLV7041DPWR equivalent, key selection considerations include its open-drain output architecture, 5-pin SOT-23 package, –40°C to 125°C operating range, and compatibility with 1.6V–6.5V supply rails in space-constrained, low-power designs.
Technical Context
The TLV7041DPWR implements a rail-to-rail input stage capable of accepting signals up to 100mV beyond VCC, paired with an open-drain output that supports pull-up voltages exceeding VCC - making it suitable for level translation and bipolar-to-single-ended conversion. Its internal hysteresis (2–17mV) suppresses noise-induced output oscillation during slow-moving input transitions.
It integrates a power-on-reset (POR) circuit that places the output in high-impedance state until VCC reaches ≥1.6V, ensuring glitch-free startup. The device is specified across –40°C to +125°C and maintains 315nA typical ICC over full temperature and supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - supports direct operation from single Li-ion, 3V, or 5V rails without regulation. |
| Quiescent Current | 315nA typical - enables multi-year battery life in always-on sensor nodes. |
| Propagation Delay | 3µs typical at 5V - balances speed and power for fault-detection response in safety-critical monitors. |
| Input Offset Voltage | ±0.1mV min, ±8mV max - ensures accurate threshold comparison under temperature and supply variation. |
| Hysteresis | 2–17mV - prevents chatter on noisy inputs without external components. |
| Common-Mode Input Range | Rail-to-rail (VEE to VCC + 0.1V) - accommodates inputs beyond supply rails for flexible signal conditioning. |
| Output Type | Open-drain - allows wired-OR logic, level shifting, and interface with higher-voltage digital systems. |
Pinout & Package
TLV7041DPWR is packaged in a 5-pin SOT-23 (DBV) package measuring 2.90mm × 1.60mm, with standard "North West" pinout orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Open-drain output | Requires external pull-up; sinks current when active; high-Z when inactive - enables level translation and bus sharing. |
| 2: IN− | Inverting input | Differential input node; accepts rail-to-rail signals including below VEE and above VCC by up to 0.1V. |
| 3: IN+ | Non-inverting input | Differential input node; same rail-to-rail capability as IN−; used for threshold reference or signal monitoring. |
| 4: VEE | Negative supply / ground | Reference for input common-mode and output low state; tied to system ground in single-supply operation. |
| 5: VCC | Positive supply | Primary power rail; POR activates below 1.6V; output remains high-Z until stable. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 315nA enables >10-year operation on CR2032 coin cell in wake-on-event sensor applications. |
| Internal hysteresis | Eliminates need for external positive feedback resistors - reduces BOM count and PCB area in smoke/gas detector designs. |
| Rail-to-rail input stage | Accepts input signals from VEE − 0.1V to VCC + 0.1V - simplifies interfacing with unbuffered transducer outputs. |
| Open-drain output | Supports mixed-voltage I/O (e.g., 5V pull-up with 1.8V VCC) and wired-AND bus configurations for multi-sensor alarm systems. |
| Wide temperature range | –40°C to +125°C operation ensures reliability in automotive cabin sensors and industrial metering enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7041DBVR | Same electrical specs and pinout; differs only in tape-and-reel packaging (DBVR vs DPWR). | No functional difference; both rated for –40°C to 125°C and share identical SOT-23 footprint. | Select TLV7041DBVR for automated pick-and-place with different reel size or quantity requirements. |
| MAX9021AUT+T | Higher 1.1µA ICC, 120ns propagation delay, SC70-5 package; no internal hysteresis. | Better speed but 3.5× higher current draw; requires external hysteresis resistor for noise immunity. | Choose only if sub-200ns response is mandatory and battery life is secondary to timing precision. |
Compared with TLV7041DBVR, TLV7041DPWR offers identical performance in a functionally interchangeable package; versus MAX9021AUT+T, TLV7041DPWR provides 3.5× lower power and integrated hysteresis at the cost of 25× slower propagation - favoring energy-constrained, noise-prone environments over high-speed control loops.

FAQ
What is the maximum supply voltage for TLV7041DPWR?
The absolute maximum supply voltage (VCC – VEE) for TLV7041DPWR is 7V. However, the recommended operating range is 1.6V to 6.5V. Exceeding 7V risks permanent damage per Absolute Maximum Ratings. Operation at 6.5V is fully characterized and supported across –40°C to +125°C, making TLV7041DPWR suitable for 5V and unregulated 6V battery systems.
Does TLV7041DPWR require external hysteresis resistors?
No, TLV7041DPWR includes internal hysteresis of 2–17mV, eliminating the need for external positive feedback components. This is confirmed in the Features list and Section 6.3 of the datasheet. The hysteresis is factory-trimmed and temperature-stable, providing consistent noise immunity across –40°C to +125°C without design overhead - a key advantage over comparators like MAX9021AUT+T.
Can TLV7041DPWR operate from a 1.2V supply?
No - TLV7041DPWR has a minimum recommended supply voltage of 1.6V. While the "S" and "L" variants (e.g., TLV7041S, TLV7041L) support 1.2V minimum, TLV7041DPWR uses the standard "North West" pinout and is not rated for operation below 1.6V. Attempting 1.2V operation results in undefined behavior, including failure of the power-on-reset circuit and unreliable output states.
What is the output leakage current of TLV7041DPWR when pulled high?
When the TLV7041DPWR output is in high-impedance state (i.e., not sinking current), its open-drain leakage is ≤100pA at 5V supply and +0.1V output voltage, as specified in Electrical Characteristics Table 5.7. This ultra-low leakage ensures minimal power loss in high-value pull-up configurations - critical for maintaining battery voltage accuracy in long-life gas meter designs.
Is TLV7041DPWR pin-compatible with legacy LMC7211 comparators?
No - TLV7041DPWR uses the standard "North West" SOT-23 pinout (OUT, IN−, IN+, VEE, VCC), whereas LMC7211 uses a different pin assignment. The TLV7041L variant was specifically created for LMC72xx drop-in replacement, but TLV7041DPWR is not compatible. Board redesign is required to substitute TLV7041DPWR for LMC7211 due to pinout mismatch and differing supply requirements.
