Product details
Overview
TLV7041QDCKRQ1 from Texas Instruments is an automotive-grade, single-channel, open-drain nanopower comparator with rail-to-rail input capability, 315 nA quiescent current, 3 µs propagation delay, and 6.5 mV internal hysteresis-designed for precision voltage monitoring in telematics eCall and instrument cluster systems.
For engineers reviewing the TLV7041QDCKRQ1 datasheet, TLV7041QDCKRQ1 pinout, TLV7041QDCKRQ1 application, or TLV7041QDCKRQ1 equivalent, this page delivers verified electrical specs, validated SC70-5 package mapping, confirmed AEC-Q100 Grade 1 qualification, and two functionally aligned alternative comparators for automotive signal conditioning designs.
Technical Context
The TLV7041QDCKRQ1 implements a rail-to-rail input stage tolerant to inputs up to 100 mV above VCC and down to VEE, with no phase reversal under overdrive. Its internal power-on-reset (POR) forces high-impedance output during supply ramp-up below 1.6 V.
It features fixed 6.5 mV hysteresis (typical at 25°C), 1 pA typical input bias current, and operates across 1.6 V–6.5 V supply range-enabling direct interface with 1.8 V, 3.3 V, and 5 V automotive microcontrollers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - supports direct integration into 1.8 V/3.3 V/5 V automotive domains without external regulators |
| Quiescent Current | 315 nA - enables always-on fault monitoring in battery-backed systems with multi-year runtime |
| Propagation Delay | 3 µs - provides fast response to overvoltage/undervoltage events while maintaining ultra-low power |
| Input Offset Voltage | ±0.1 mV (min), ±8 mV (max) - ensures accurate threshold detection across –40°C to +125°C |
| Internal Hysteresis | 6.5 mV (typical) - suppresses noise-induced chatter on slow-moving sensor signals in noisy vehicle environments |
| Common-Mode Range | VEE to VCC + 0.1 V - allows direct sensing of signals beyond supply rails (e.g., battery voltage monitoring) |
| Output Type | Open-drain - enables wired-OR logic, flexible pull-up to higher voltage rails, and compatibility with I²C-style bus architectures |
Pinout & Package
TLV7041QDCKRQ1 is packaged in a 5-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Open-drain output | Drives low actively; requires external pull-up for high state-supports mixed-voltage interfacing and bus arbitration |
| 2: VEE | Negative supply / ground | Reference node for single-supply operation; tied to system GND in most automotive applications |
| 3: IN+ | Noninverting input | Positive reference input terminal; accepts rail-to-rail common-mode signals up to VCC + 0.1 V |
| 4: IN− | Inverting input | Negative reference input terminal; identical voltage range and fault-tolerant behavior as IN+ |
| 5: VCC | Positive supply | Primary power input (1.6–6.5 V); isolated from inputs to allow safe input driving even when unpowered |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation-meets automotive infotainment and body electronics thermal requirements |
| Internal power-on-reset (POR) | Guarantees known high-impedance output state during power ramp-up, preventing spurious logic transitions at startup |
| Rail-to-rail input with overvoltage tolerance | Accepts inputs from VEE to VCC + 0.1 V-enables direct battery voltage or sensor monitoring without external resistive dividers |
| No phase reversal under overdrive | Ensures deterministic output behavior even when inputs exceed supply rails-critical for robust fault detection |
| 2 pA max input bias current | Minimizes loading on high-impedance sensor sources (e.g., thermistors, potentiometers) across full temperature range |
Applications
| Telematics eCall System | Automotive Instrument Cluster |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7041QDBVRQ1 | SOT-23-5 package (2.90 mm × 1.60 mm); identical electrical specs and AEC-Q100 Grade 1 rating | Larger footprint but higher thermal mass; preferred for manual assembly or thermal-stress-sensitive layouts | Select when board-level rework, thermal dissipation margin, or legacy SOT-23 tooling is required |
| LM7321QMA/NOPB | Rail-to-rail input/output op-amp (not comparator); 1.3 mA IQ; 20 MHz GBW; no internal hysteresis or POR | Requires external hysteresis network and power sequencing control; suited for active filtering or precision amplification, not threshold detection | Choose only if design requires programmable gain or analog signal conditioning-not for direct replacement in comparator roles |
Compared with TLV7041QDCKRQ1, TLV7041QDBVRQ1 offers identical functionality in a larger SOT-23 package for easier handling and thermal management, while LM7321QMA/NOPB serves a fundamentally different circuit role requiring external components to emulate comparator behavior-making TLV7041QDCKRQ1 the optimal choice for low-power, integrated threshold detection in automotive systems.

FAQ
What is the operating temperature range of the TLV7041QDCKRQ1?
The TLV7041QDCKRQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to +125°C. This specification is validated across all electrical parameters in the datasheet and applies directly to the TLV7041QDCKRQ1 in its SC70 package. The device maintains guaranteed performance-including 315 nA quiescent current and 3 µs propagation delay-within this full automotive temperature envelope.
Does the TLV7041QDCKRQ1 include internal hysteresis, and what is its value?
Yes, the TLV7041QDCKRQ1 includes fixed internal hysteresis of 6.5 mV (typical at 25°C), with a min/max range of 2 mV to 17 mV across temperature and supply conditions. This hysteresis is factory-trimmed and does not require external components. It is explicitly specified in the Electrical Characteristics table (Section 6.7) of the TLV7041QDCKRQ1 datasheet and is critical for noise immunity in automotive applications like instrument cluster light sensing.
What is the output configuration of the TLV7041QDCKRQ1, and how does it differ from the TLV7031QDCKRQ1?
The TLV7041QDCKRQ1 features an open-drain output, requiring an external pull-up resistor to define the high-state voltage. In contrast, the TLV7031QDCKRQ1 uses a push-pull output capable of both sourcing and sinking current. This distinction is fundamental: TLV7041QDCKRQ1 supports wired-OR logic and mixed-voltage interfacing, while TLV7031QDCKRQ1 drives CMOS loads directly. Both share identical supply range, quiescent current, and hysteresis.
Is the TLV7041QDCKRQ1 pin-compatible with other devices in the TLV70xx-Q1 family?
The TLV7041QDCKRQ1 shares the same 5-pin SC70 (DCK) pinout with TLV7031QDCKRQ1, as confirmed in Figure 5-1 and Table 5-1 of the datasheet. However, it is not pin-compatible with dual (TLV7042) or quad (TLV7044) variants, which use 8-pin VSSOP and 14-pin TSSOP packages respectively. Pin compatibility is strictly limited to the single-channel SC70 variants-TLV7041QDCKRQ1 and TLV7031QDCKRQ1-and does not extend across channel count or package types.
What packaging and marking information is associated with the TLV7041QDCKRQ1?
The TLV7041QDCKRQ1 is supplied in a 5-pin SC70 (DCK) package with nominal dimensions of 2.00 mm × 1.25 mm. Per TI's orderable addendum, the device marking code is "YU" on the top surface. This marking is consistent across all TLV7041-Q1 SC70 variants and is laser-etched for traceability. The DCK package is RoHS-compliant and qualified for lead-free reflow per J-STD-020.
