Product details
Overview
TLV7041QDBVRQ1 from Texas Instruments is a single-channel, AEC-Q100 Grade 1 automotive-grade comparator with open-drain output, rail-to-rail input stage, 315 nA quiescent current, 3 µs propagation delay, and 6.5 mV internal hysteresis - used for precision voltage monitoring in telematics eCall and instrument cluster fault-detection circuits.
For engineers reviewing the TLV7041QDBVRQ1 datasheet, TLV7041QDBVRQ1 pinout, TLV7041QDBVRQ1 application, or TLV7041QDBVRQ1 equivalent, key selection criteria include its nanopower operation at 1.6–6.5 V supply, guaranteed startup behavior via internal power-on-reset, no phase reversal under overdriven inputs, and compatibility with 1.8 V/3.3 V/5 V systems in harsh automotive environments.
Technical Context
The TLV7041QDBVRQ1 implements a rail-to-rail input stage capable of accepting signals up to 100 mV above VCC and down to VEE, with internal hysteresis (6.5 mV typ) and fault-tolerant inputs that remain high-impedance even when VCC is unpowered. Its open-drain output supports wired-OR logic and pull-up beyond VCC.
Internal power-on-reset (POR) holds the output in high-impedance state during supply ramp-up or brownout, ensuring deterministic startup. The device operates across –40°C to +125°C ambient, meeting AEC-Q100 requirements for automotive Grade 1 applications including infotainment and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V microcontrollers and sensors without level-shifting. |
| Quiescent Current | 315 nA - enables multi-year battery life in always-on automotive monitoring circuits (e.g., battery disconnect detection). |
| Propagation Delay | 3 µs - provides fast response to overvoltage/undervoltage faults while maintaining ultra-low power consumption. |
| Input Offset Voltage | ±0.1 mV (min), ±8 mV (max) - ensures accurate threshold detection across temperature and supply variations. |
| Internal Hysteresis | 6.5 mV (typ) - suppresses noise-induced chatter on slow-moving or noisy input signals (e.g., thermistor-based temperature sensing). |
| Common-Mode Input Range | VEE to VCC + 0.1 V - allows direct sensing of signals beyond the supply rail, critical for battery voltage monitoring in 12 V systems. |
| Output Type | Open-drain - enables flexible logic interfacing (wired-OR, I²C-compatible bus, external pull-up to higher voltage rail). |
Pinout & Package
TLV7041QDBVRQ1 is packaged in SC70-5 (DCK) with nominal body size 2.00 mm × 1.25 mm, optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Open-drain output requiring external pull-up; sinks current when active low, high-impedance when inactive. |
| 2 - VEE | Power (Ground) | Negative supply or system ground reference; supports single-supply operation down to 0 V. |
| 3 - IN+ | Input | Noninverting input; accepts rail-to-rail common-mode signals up to VCC + 0.1 V. |
| 4 - IN− | Input | Inverting input; same rail-to-rail range as IN+; no phase reversal when overdriven. |
| 5 - VCC | Power (Supply) | Positive supply input; powers internal bias, POR, and output stage; isolated from inputs for fault tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts inputs from VEE to VCC + 0.1 V - eliminates need for external resistive dividers in high-side sensing. |
| Internal power-on-reset (POR) | Guarantees known high-impedance output state during power ramp-up - prevents spurious logic transitions in safety-critical monitoring. |
| No phase reversal on overdrive | Output remains monotonic even when inputs exceed supply rails - essential for reliable fault detection in noisy automotive environments. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with HBM ±2 kV and CDM ±1 kV ESD robustness - meets automotive reliability standards. |
| Fault-tolerant inputs | Inputs remain high-impedance and functional even with VCC = 0 V - enables hot-plug capability and safe sensor interfacing during power sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7041DBVR | Non-automotive grade; lacks AEC-Q100 qualification, Grade 1 temp range, and automotive-specific ESD ratings. | Not suitable for production automotive ECUs; acceptable for lab prototyping or non-safety-critical industrial use. | Select TLV7041DBVR only for cost-sensitive non-automotive designs where extended temperature and qualification are unnecessary. |
| LMV7219QMF/NOPB | Higher quiescent current (1.1 µA), faster propagation delay (130 ns), push-pull output, no internal hysteresis. | Better for high-speed window comparators but requires external hysteresis and consumes >3× more power. | Choose LMV7219QMF/NOPB when speed outweighs power budget and external hysteresis design is acceptable. |
Compared with TLV7041DBVR and LMV7219QMF/NOPB, TLV7041QDBVRQ1 uniquely balances automotive qualification, nanopower operation, built-in hysteresis, and rail-to-rail input - making it optimal for battery-conscious, safety-relevant voltage monitoring where layout space and BOM count must be minimized.

FAQ
What is the maximum supply voltage rating for TLV7041QDBVRQ1?
The absolute maximum supply voltage (VCC – VEE) for TLV7041QDBVRQ1 is 7 V. Operation beyond this risks permanent damage. The recommended operating range is 1.6 V to 6.5 V, ensuring full specification compliance across –40°C to +125°C ambient temperature. Exceeding 7 V voids AEC-Q100 qualification guarantees.
Does TLV7041QDBVRQ1 require external hysteresis for stable operation?
No, TLV7041QDBVRQ1 includes 6.5 mV typical internal hysteresis, eliminating the need for external feedback resistors in most voltage-monitoring applications. This simplifies PCB layout and improves reliability in noisy automotive environments where external components could degrade over time or introduce parasitic effects.
How does the power-on-reset (POR) function behave in TLV7041QDBVRQ1?
During power ramp-up or brownout, TLV7041QDBVRQ1's internal POR circuit forces the open-drain output into high-impedance state until VCC reaches ≥1.6 V and stabilizes for ≥200 µs. This prevents undefined logic states at MCU GPIOs and ensures deterministic startup - a critical feature for ASIL-B–compliant fault-detection circuits.
Can TLV7041QDBVRQ1 inputs safely operate above VCC?
Yes - TLV7041QDBVRQ1 inputs tolerate voltages up to VCC + 0.1 V (and down to VEE – 0.3 V) without phase reversal or damage. This rail-to-rail-plus capability enables direct connection to sensors or battery rails exceeding the comparator's supply, such as monitoring a 12 V battery with a 3.3 V-powered TLV7041QDBVRQ1 using appropriate input scaling.
What package options are available for TLV7041QDBVRQ1?
TLV7041QDBVRQ1 is exclusively offered in the SC70-5 (DCK) package: 2.00 mm × 1.25 mm body size, 0.65 mm pitch, 5-pin configuration. This compact footprint supports high-density automotive PCBs where space is constrained, and thermal performance is managed via JEDEC-standard board-level conduction (RθJB = 113.2°C/W).
