Product details
Overview
TLV3701QDBVRG4Q1 from Texas Instruments is an automotive-grade nanopower comparator with push-pull CMOS output, 560nA supply current per channel, –0.1V to 16V input common-mode range, and operation from 2.7V to 16V supply. It delivers reverse battery protection up to 18V and operates across –40°C to 125°C for use in always-on vehicle subsystems such as battery monitoring and intrusion detection.
For engineers reviewing the TLV3701QDBVRG4Q1 datasheet, TLV3701QDBVRG4Q1 pinout, TLV3701QDBVRG4Q1 application, or TLV3701QDBVRG4Q1 equivalent, key selection considerations include its rail-to-rail input capability beyond V+, internal hysteresis (1–5mV), power-on reset behavior (output held low for 3ms), and fail-safe inputs tolerant of –0.1V to 16V independent of supply state.
Technical Context
The TLV3701QDBVRG4Q1 implements a high-voltage nanopower comparator architecture with dual-input operating modes: within-rail (0V to V+–1V, <1pA bias) and over-rail (up to 16V, ~55nA bias). Its input stage avoids diode clamping to V+, enabling robust operation during unpowered or brownout conditions.
It integrates a dedicated Power-On Reset circuit that holds the push-pull output low for 3ms after V+ crosses 1.5V, ensuring deterministic startup. The output stage sources/sinks current without external pull-ups and includes ESD protection exceeding 2kV (MIL-STD-883) and 200V (machine model).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 560nA per channel at 25°C - enables multi-year battery life in always-on automotive sensors |
| Input Common-Mode Range | –0.1V to 16V - supports direct sensing of battery voltage, load dumps, or reverse-battery transients without level-shifting |
| Supply Voltage Range | 2.7V to 16V - compatible with 3.3V/5V logic domains and 12V automotive systems |
| Propagation Delay (LH) | 14µs typical at 100mV overdrive, CL=10pF - sufficient for slow-varying signals like temperature or battery SOC thresholds |
| Input Offset Voltage | 250µV typical, 5000µV max at 25°C - ensures accurate threshold detection in precision voltage monitoring |
| Hysteresis | 1–5mV typical - suppresses noise-induced chatter on marginal input transitions |
| Operating Temperature | –40°C to 125°C - qualified for under-hood and cabin-mounted automotive electronics |
Pinout & Package
SOT-23-5 (DBV) package: ultrasmall 2.9mm × 1.6mm footprint, 5-pin surface-mount, tape-and-reel (3000 pcs/reel), RoHS-compliant, NIPDAU lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Push-pull CMOS output | Drives loads directly (e.g., MOSFET gate or LED); no external pull-up required; must not be shorted to rails above 12V |
| 2 (V−) | Negative supply terminal | Typically connected to GND; serves as reference for ESD clamps and internal bias networks |
| 3 (IN+) | Non-inverting input | High-impedance node (≥300MΩ); accepts voltages from –0.1V to 16V regardless of V+ state |
| 4 (IN−) | Inverting input | Identical electrical characteristics to IN+; unused channels require ≥50mV differential bias to prevent oscillation |
| 5 (V+) | Positive supply terminal | Accepts 2.7V–16V; reverse battery protection guards against –18V transients on this pin |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe inputs | Withstand –0.1V to 16V independent of V+ supply - eliminates need for external clamping or power sequencing |
| Power-On Reset (POR) | Holds OUT low for 3ms after V+ crosses 1.5V - guarantees known startup state in battery-powered modules |
| Reverse battery protection | Internal circuitry withstands –18V on V+ pin - prevents damage from incorrect battery installation in 12V systems |
| Over-rail input operation | Inputs functional up to 16V even when V+ = 2.7V - enables direct high-side voltage sensing without dividers |
| ESD robustness | 2000V HBM, 200V machine model - meets automotive reliability requirements for exposed sensor interfaces |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701QDBVRQ1 | No G4 suffix; identical electrical specs and packaging; same RoHS status and MSL rating | Same automotive qualification, temperature range, and pinout - functionally identical | Select TLV3701QDBVRQ1 if G4 marking is not required for traceability or legacy BOM alignment |
| TLV3401QDBVRQ1 | Lower supply current (470nA typ), same 2.5–16V supply, open-drain output (not push-pull) | Requires external pull-up; unsuitable where active drive or rail-to-rail output swing is needed | Choose TLV3401QDBVRQ1 only when lowest possible current dominates and output loading permits open-drain topology |
Compared with TLV3701QDBVRQ1, the TLV3701QDBVRG4Q1 offers identical performance with enhanced traceability via G4 marking; versus TLV3401QDBVRQ1, it provides push-pull drive capability critical for direct MOSFET gating or LED activation without added components.

FAQ
What is the maximum input voltage the TLV3701QDBVRG4Q1 can tolerate without damage?
The TLV3701QDBVRG4Q1 supports an absolute maximum input voltage of –0.3V to 20V per pin, with fail-safe operation specified from –0.1V to 16V independent of supply voltage. Inputs remain high-impedance and undamaged even when V+ is unpowered, making TLV3701QDBVRG4Q1 ideal for hot-swap or unregulated sensor interfaces in automotive systems.
Does the TLV3701QDBVRG4Q1 have internal hysteresis, and what is its typical value?
Yes, the TLV3701QDBVRG4Q1 includes internal hysteresis with a typical value of 2.8mV and a range of 1mV to 5mV. This hysteresis is fixed and non-adjustable, providing noise immunity for slow-moving signals such as battery voltage decay or temperature drift - a key design feature confirmed in the Electrical Characteristics table of the TLV3701QDBVRG4Q1 datasheet.
How does the Power-On Reset (POR) function in the TLV3701QDBVRG4Q1?
The TLV3701QDBVRG4Q1 incorporates an internal POR circuit that activates when V+ crosses 1.5V and holds the push-pull output low for 3ms. This ensures a defined initial state during power ramp-up or brownout recovery. After the 3ms delay, the output reflects the actual IN+ vs. IN− comparison - a behavior explicitly documented in Section 7.4.5 of the TLV3701QDBVRG4Q1 datasheet.
Can the TLV3701QDBVRG4Q1 operate with a single 3.3V supply while sensing a 12V signal?
Yes. The TLV3701QDBVRG4Q1 supports over-rail input operation: its inputs function correctly from –0.1V to 16V regardless of V+ level. With V+ = 3.3V, the device can directly compare a 12V battery signal against a 3.3V reference without external level-shifting circuitry - a capability verified in the Recommended Operating Conditions and Feature Description sections for TLV3701QDBVRG4Q1.
What is the output drive capability of the TLV3701QDBVRG4Q1 push-pull stage?
The TLV3701QDBVRG4Q1 push-pull output sources up to ~100µA at VOH = (V+) – 0.32V and sinks up to ~50µA at VOL = 80mV (at 25°C, V+ = 12V). It is designed to drive light loads such as MOSFET gates or indicator LEDs directly. However, direct shorting to V+ or V− at >12V supply risks thermal runaway - a series current-limiting resistor is recommended if output shorts are possible, as stated in Section 7.4.3.1 of the TLV3701QDBVRG4Q1 datasheet.
