Product details
Overview
TLV6703QDSERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive comparator with integrated 400-mV reference, open-drain output rated to 18 V, ±0.5% threshold accuracy at 25°C, 5.5 µA typical quiescent current, and built-in 5.5-mV hysteresis - used for precision undervoltage monitoring in battery-supervised systems.
For engineers reviewing the TLV6703QDSERQ1 datasheet, TLV6703QDSERQ1 pinout, TLV6703QDSERQ1 application, or TLV6703QDSERQ1 equivalent, this page delivers verified electrical specs, WSON-6 package layout guidance, automotive-grade thermal and ESD performance data, and real-world voltage-monitoring implementation details.
Technical Context
The TLV6703QDSERQ1 implements a non-inverting single-channel comparator architecture with internal 400-mV reference and fixed hysteresis (5.5 mV typ), enabling stable threshold detection across 1.8 V–18 V supply range. Its SENSE pin accepts input voltages up to 6.5 V independent of VDD, supporting rail monitoring beyond supply voltage via external resistor dividers.
It features undervoltage lockout (UVLO = 1.3–1.7 V) and power-on reset (VPOR = 0.8 V), ensuring deterministic output behavior during power ramp-up. The open-drain OUT pin sinks up to 40 mA and supports pullup to 18 V regardless of VDD, enabling direct interface with higher-voltage logic or reset controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 18 V - enables direct operation from 12-V automotive battery rails without LDO pre-regulation. |
| Threshold Accuracy | ±0.5% max at 25°C, ±1.0% max over –40°C to +125°C - ensures reliable trip-point consistency in engine bay environments. |
| Quiescent Current | 5.5 µA typical - supports always-on battery supervision with negligible standby drain. |
| Hysteresis | 5.5 mV typical - suppresses false triggering from noise on monitored rails like OBC or head unit supplies. |
| Output Sink Capability | 40 mA max - drives standard GPIOs or resets without external buffer, even when pulled up to 18 V. |
| Input Leakage Current | ±25 nA max - permits use of high-value resistor dividers (e.g., >1 MΩ) without accuracy degradation. |
| Propagation Delay | 18 µs (HL), 29 µs (LH) at 5 V - provides timely fault response while avoiding transient-induced chatter. |
Pinout & Package
Package: WSON-6 (DSE), 1.50 mm × 1.50 mm, leadless, wettable flank, RoHS-compliant, MSL Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 3, 5) | Ground reference | All three pins must be connected to system ground; low-inductance grounding improves noise immunity and thermal dissipation. |
| VDD (Pin 2) | Power supply input | Accepts 1.8–18 V; requires local 0.1-µF ceramic decoupling capacitor for stable operation under load transients. |
| SENSE (Pin 4) | High-impedance input | Monitors external voltage via resistor divider; supports inputs up to 6.5 V regardless of VDD; <25 nA leakage preserves divider accuracy. |
| OUT (Pin 6) | Open-drain output | Sinks up to 40 mA; compatible with pullup to 18 V; asserts low when SENSE falls below VIT– (≈394.5 mV); high-impedance otherwise. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation, HBM ±2500 V, CDM ±1000 V - meets automotive reliability requirements. |
| Integrated 400-mV reference | Trimmed to ±0.5% at 25°C; drift ≤±4 mV over temperature - eliminates need for external reference IC or precision resistors. |
| Wide VDD-compatible output | OUT rated to 18 V regardless of VDD - enables direct interfacing with 3.3-V, 5-V, or 12-V microcontroller reset inputs. |
| Internal hysteresis | 5.5 mV typical - rejects sub-10-µs noise spikes without requiring external RC filtering components. |
| Low-power undervoltage lockout | UVLO threshold 1.3–1.7 V - prevents erratic output during brownout conditions while maintaining ultra-low IDD. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6703DSER | Non-automotive version; same electrical specs but lacks AEC-Q100 qualification and Grade 1 temp range. | Not suitable for under-hood or safety-critical automotive functions; limited to cabin or industrial use. | Select TLV6703DSER only for cost-sensitive non-automotive designs where AEC-Q100 compliance is unnecessary. |
| TLV6713QDSERQ1 | Wider 1.8–36 V supply range; tighter 0.75% threshold accuracy over temperature; identical WSON-6 package. | Better suited for 24-V commercial vehicles or 48-V mild-hybrid architectures requiring extended VIN tolerance. | Choose TLV6713QDSERQ1 when monitoring 24-V or 48-V rails; TLV6703QDSERQ1 remains optimal for standard 12-V systems. |
Compared with TLV6703QDSERQ1, TLV6703DSER omits automotive qualification and thermal grading, while TLV6713QDSERQ1 extends supply range and improves accuracy for higher-voltage platforms - both retain pin compatibility but differ in qualification scope and voltage capability.

FAQ
What is the maximum input voltage allowed at the SENSE pin of the TLV6703QDSERQ1?
The TLV6703QDSERQ1 SENSE pin supports input voltages from 0 V to 6.5 V, independent of the VDD supply voltage. This allows direct monitoring of rails exceeding the device's own supply - for example, using a resistor divider to detect faults on a 48-V auxiliary bus while powering the TLV6703QDSERQ1 from a local 5-V LDO. Exceeding 6.5 V risks damage per absolute maximum ratings.
Does the TLV6703QDSERQ1 require an external reference or precision resistors for threshold setting?
No. The TLV6703QDSERQ1 integrates a factory-trimmed 400-mV reference with ±0.5% accuracy at 25°C and ±1.0% over temperature, eliminating the need for external references. Threshold voltage is set solely by an external resistor divider on the SENSE pin; high input impedance (±25 nA leakage) permits use of large-value resistors without accuracy loss.
Can the TLV6703QDSERQ1 output drive a 3.3-V microcontroller GPIO directly?
Yes. The TLV6703QDSERQ1 features an open-drain output that can be pulled up to any voltage between 1.8 V and 18 V. To interface with a 3.3-V microcontroller, connect a pullup resistor from OUT to the 3.3-V rail. The output sinks up to 40 mA and maintains VOL ≤ 250 mV at 5 mA sink current, ensuring clean logic-low recognition.
How does the TLV6703QDSERQ1 handle power supply brownouts during vehicle start-stop cycles?
The TLV6703QDSERQ1 incorporates undervoltage lockout (UVLO = 1.3–1.7 V) and power-on reset (VPOR = 0.8 V) circuitry. During brownout, OUT is forced low when VDD falls below UVLO, preventing spurious resets. Once VDD exceeds 1.8 V for ≥150 µs, normal operation resumes - ensuring robust behavior across cranking transients down to 6 V.
Is the TLV6703QDSERQ1 pin-compatible with other devices in the TLV67xx family?
Yes. The TLV6703QDSERQ1 shares identical WSON-6 (DSE) pinout and function mapping with TLV6703DSER, TLV6700QDSERQ1, and TLV6713QDSERQ1. However, functional differences exist: TLV6700 variants are window comparators, while TLV6713QDSERQ1 supports up to 36 V supply. Always verify electrical compatibility per application requirements.
