Product details
Overview
TLV7041DCKR from Texas Instruments is a single-channel, nanopower, open-drain output comparator in SC-70-5 package. It operates from 1.6V to 6.5V supply, draws only 315nA quiescent current, delivers 3µs propagation delay, and supports rail-to-rail common-mode input voltage - enabling precision voltage monitoring in battery-powered gas detectors and motion sensors.
For engineers reviewing the TLV7041DCKR datasheet, TLV7041DCKR pinout, TLV7041DCKR application, or TLV7041DCKR equivalent, this page provides verified pin functions, confirmed operating temperature (–40°C to 125°C), exact hysteresis range (2–17mV), open-drain leakage (≤100pA), and validated alternative options for low-power comparator selection.
Technical Context
The TLV7041DCKR implements a rail-to-rail input stage capable of accepting signals up to 100mV beyond VCC, with internal hysteresis (2–17mV) to prevent chatter on slow-moving inputs. Its open-drain output allows level translation beyond VCC and supports wired-OR configurations.
It features a power-on-reset (POR) circuit that places the output in high-impedance state during supply ramp-up or ramp-down below 1.6V, ensuring glitch-free startup. Input bias current is ≤2pA and offset voltage is ±0.1mV (min) to ±8mV (max) across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 6.5V - compatible with 1.8V, 3.3V, and 5V systems without level-shifting |
| Quiescent Current | 315nA - enables >10-year battery life in coin-cell–powered smoke detectors |
| Propagation Delay | 3µs - fast enough to detect transient fault conditions while maintaining nanoPower operation |
| Input Offset Voltage | ±0.1mV (min) to ±8mV (max) - supports accurate threshold detection in precision sensor interfaces |
| Hysteresis | 2mV to 17mV - suppresses noise-induced oscillation on noisy industrial sensor inputs |
| Open-Drain Leakage | ≤100pA at VID = +0.1V - ensures reliable high-state pull-up in multi-comparator bus configurations |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin and industrial motor-control environments |
Pinout & Package
TLV7041DCKR uses the SC-70-5 (DCK) package: 2.00mm × 1.25mm body, 0.65mm pitch, leadless, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Open-drain output | Requires external pull-up; sinks current when active; floats when inactive |
| 2: IN− | Inverting input | Differential input node; accepts rail-to-rail common-mode voltage (VEE to VCC+0.1V) |
| 3: IN+ | Non-inverting input | Differential input node; same common-mode range as IN− |
| 4: VEE | Negative supply / ground | Reference for input common-mode and output low state; must be ≤ IN−/IN+ |
| 5: VCC | Positive supply | Primary power rail; powers internal bias and POR circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts input signals up to 100mV beyond VCC, eliminating need for external clamping in overvoltage-prone sensor front-ends |
| Internal hysteresis | 2–17mV programmable via supply and temperature - reduces external component count in noisy industrial environments |
| No phase reversal | Output remains stable even when inputs exceed common-mode range - critical for robust fault detection in servo position sensors |
| Power-on-reset (POR) | Forces output into high-Z state until VCC ≥ 1.6V - prevents false triggers during brown-out or cold-start sequences |
| Ultra-low input bias current | ≤2pA - preserves signal integrity in high-impedance pH or gas sensor bridges without loading error |
Applications
| Gas Detection System | Motion Sensing Node |
|---|---|
Use Scenario: Detects toxic gas concentration thresholds using electrochemical sensor output voltage. IC Role / Device Role / Timing Role: Comparator compares sensor voltage against reference; open-drain output drives microcontroller interrupt line via shared pull-up. Use Value: 315nA quiescent current extends battery life in portable gas meters; 3µs response detects rapid CO leaks before hazardous accumulation. | Use Scenario: Monitors PIR sensor output to trigger wake-up in ultra-low-power occupancy sensors. IC Role / Device Role / Timing Role: Compares analog PIR envelope against adjustable threshold; hysteresis prevents false triggers from thermal noise. Use Value: Rail-to-rail input captures full PIR swing without external amplification; –40°C to 125°C rating ensures reliability in outdoor lighting fixtures. |
| Smart Smoke Detector | Battery-Powered Servo Feedback |
Use Scenario: Compares ionization chamber current-derived voltage to alarm threshold in residential smoke alarms. IC Role / Device Role / Timing Role: Single-supply comparator referenced to ground (VEE = GND); open-drain output interfaces directly with MCU GPIO. Use Value: 1.6V minimum supply allows operation down to near-dead battery voltage; internal hysteresis eliminates nuisance alarms from EMI. | Use Scenario: Converts analog potentiometer feedback from servo motor shaft into clean digital position status. IC Role / Device Role / Timing Role: Threshold detector for closed-loop position verification; output toggles when shaft reaches endpoint. Use Value: ≤2pA input bias avoids loading high-resistance potentiometer; SC-70 package saves space on compact motor control PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7041DBVR | SOT-23-5 package (2.90mm × 1.60mm); identical electrical specs and pinout (DCK "South East" variant) | Larger footprint; better thermal dissipation (RθJA = 297°C/W vs 279°C/W); preferred for higher ambient temperature designs | Select TLV7041DBVR when board layout allows larger package and thermal margin is critical. |
| MAX9021AUT+T | 350nA ICC, 5.5µs tPD, 3.5mV VHYS; SOT-23-5; no internal POR; requires external hysteresis resistor network | Higher power and slower response; lacks integrated POR and rail-to-rail input - needs external support components | Choose MAX9021AUT+T only if legacy design compatibility or specific vendor qualification requirements mandate Maxim parts. |
Compared with TLV7041DBVR, TLV7041DCKR offers 15% smaller PCB area and tighter thermal resistance to board (113.2°C/W vs 200.1°C/W), while matching all key specs. Against MAX9021AUT+T, TLV7041DCKR delivers lower power, faster response, integrated hysteresis and POR - reducing BOM count and improving system reliability.

FAQ
What is the maximum supply voltage for TLV7041DCKR?
The absolute maximum supply voltage (VCC – VEE) for TLV7041DCKR is 7V. However, the recommended operating range is 1.6V to 6.5V. Exceeding 6.5V may cause parametric degradation or reliability risk, and operation above 7V risks permanent damage per Absolute Maximum Ratings.
Does TLV7041DCKR support rail-to-rail input voltage?
Yes, TLV7041DCKR supports rail-to-rail common-mode input voltage from VEE to VCC + 0.1V. Its input stage can accept signals up to 100mV beyond the positive supply rail - a key advantage for interfacing with unbuffered sensors or mismatched voltage domains without external level-shifting.
Can TLV7041DCKR replace TLV7041DBVR in an existing design?
Yes, TLV7041DCKR is a direct functional replacement for TLV7041DBVR with identical pinout (SC-70 "South East" configuration), electrical specifications, and thermal behavior. The only difference is package size: DCK (2.00mm × 1.25mm) is smaller than DBVR (2.90mm × 1.60mm), so PCB layout revision is required for footprint compatibility.
What is the purpose of the internal hysteresis in TLV7041DCKR?
The internal hysteresis in TLV7041DCKR (2–17mV, depending on supply and temperature) prevents output oscillation when input signals are near the switching threshold - especially critical in noisy environments like motor-driven gas meters or HVAC duct sensors. It eliminates need for external hysteresis resistors, simplifying design and saving board space.
Is TLV7041DCKR suitable for automotive applications?
TLV7041DCKR is qualified for operation from –40°C to +125°C and meets JEDEC JESD22-A114 HBM ±2000V and JESD22-C101 CDM ±1000V ESD ratings. While not AEC-Q100 certified, its temperature range and robustness make it suitable for under-hood and cabin applications where formal automotive qualification is not mandated - e.g., auxiliary comfort sensors or non-safety-critical subsystems.
