Product details
Overview
TLV6703DSER from Texas Instruments is a micropower, 18-V comparator with integrated 400-mV reference, open-drain output rated to 18 V, ±0.5% threshold accuracy at 25°C, and 5.5 µA typical quiescent current - used for precision undervoltage monitoring in battery-powered systems.
For engineers reviewing the TLV6703DSER datasheet, TLV6703DSER pinout, TLV6703DSER application, or TLV6703DSER equivalent, this page delivers verified package mapping (WSON-6), confirmed SENSE/OUT/GND/VDD terminal roles, real-world timing (29 µs low-to-high propagation delay), thermal specs (RθJA = 194.9°C/W), and two validated alternative comparators for voltage-monitoring designs.
Technical Context
The TLV6703DSER implements a non-inverting single-channel comparator architecture with internal 400-mV reference and fixed 5.5-mV typical hysteresis. Its SENSE input accepts voltages up to 6.5 V independent of VDD, enabling rail-agnostic monitoring across 1.8–18 V supply range.
It features undervoltage lockout (UVLO = 1.3–1.7 V) and power-on reset (V(POR) = 0.8 V), ensuring deterministic output behavior during power ramp-up. The open-drain OUT supports pullup to 18 V regardless of VDD, allowing direct interface with higher-voltage logic or reset inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.8 V to 18 V - powers directly from Li-ion, 12-V industrial, or multi-rail systems without LDO pre-regulation. |
| Threshold accuracy | ±0.5% max at 25°C - enables precise 10.99-V undervoltage detection on 12-V rails with <±120 mV error. |
| Quiescent current | 5.5 µA typical - extends battery life in always-on door/window sensors and portable medical devices. |
| Hysteresis | 5.5 mV typical - rejects noise spikes ≤10 µs duration, eliminating false triggers in noisy automotive or industrial environments. |
| Output sink capability | 40 mA max - drives standard GPIO reset pins or small relays without external buffer transistors. |
| Propagation delay | 29 µs (low-to-high), 18 µs (high-to-low) - supports fast response to supply faults while maintaining stability under transient conditions. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor IoT node deployments. |
Pinout & Package
TLV6703DSER uses the WSON-6 (DSE) package: 1.50 mm × 1.50 mm, leadless, exposed thermal pad, Level-1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (pins 1, 3, 5) | Ground reference | All three pins must be connected to system ground; provides low-inductance return path and thermal conduction via exposed pad. |
| OUT (pin 6) | Open-drain output | Sinks current when SENSE falls below VIT–; high-impedance otherwise; supports pullup to 18 V independent of VDD. |
| SENSE (pin 4) | Input sensing node | Monitors divided rail voltage; accepts 0–6.5 V regardless of VDD; input leakage ≤25 nA enables >1-MΩ resistor dividers. |
| VDD (pin 2) | Power supply input | Accepts 1.8–18 V; requires 0.1-µF ceramic capacitor placed adjacent to pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400-mV reference | Eliminates external reference IC or precision resistor network, reducing BOM count and layout area in space-constrained wearables. |
| 18-V output rating | Enables direct interfacing with 3.3-V, 5-V, or 12-V microcontroller reset inputs without level-shifting circuitry. |
| Low input bias current | ±25 nA max allows use of high-value resistor dividers (e.g., 2.21 MΩ/83.5 kΩ) without degrading threshold accuracy. |
| Internal UVLO and POR | Guarantees known output state during power-up/down sequences - critical for fail-safe reset generation in safety-critical systems. |
| Thermal performance | RθJA = 194.9°C/W (WSON-6) supports operation at full load in sealed enclosures up to +85°C ambient without heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6700DDCR | Window comparator (dual-threshold); same 1.8–18 V range, 1% accuracy, but lacks internal reference - requires external resistive divider for both thresholds. | Used where overvoltage AND undervoltage detection are required simultaneously (e.g., battery charge termination). | Select TLV6700DDCR only if dual-threshold functionality is needed; TLV6703DSER is simpler and lower-cost for single-threshold monitoring. |
| TLV6713DSER | Higher 1.8–36 V operating range; 0.75% threshold accuracy; same WSON-6 package and pinout - true drop-in replacement for extended-voltage applications. | Required when monitoring 24-V industrial rails or PoE-powered equipment where 18-V limit is insufficient. | Choose TLV6713DSER when input voltage exceeds 18 V; otherwise TLV6703DSER offers better cost/performance for ≤18-V systems. |
Compared with TLV6700DDCR, TLV6703DSER simplifies design by integrating the reference and reducing external components; compared with TLV6713DSER, it provides tighter cost control and identical performance for all 18-V-or-lower monitoring tasks.

FAQ
What is the maximum input voltage allowed on the SENSE pin of TLV6703DSER?
The SENSE pin of TLV6703DSER accepts voltages from 0 V to 6.5 V, independent of the VDD supply voltage. This allows safe monitoring of rails higher than VDD (e.g., 12-V rail while VDD = 3.3 V) using an external resistor divider. Exceeding 6.5 V risks damage per absolute maximum ratings.
Does TLV6703DSER require an external reference voltage?
No, TLV6703DSER integrates a precision 400-mV reference internally. This eliminates the need for external reference ICs or trimmed resistor networks, reducing component count and board area. The reference is factory-trimmed to ±0.5% accuracy at 25°C and ±1.0% over –40°C to +125°C.
Can TLV6703DSER drive a 3.3-V microcontroller reset pin directly?
Yes - TLV6703DSER's open-drain OUT pin can be pulled up to 3.3 V (or any voltage up to 18 V) independently of VDD. When VDD = 1.8 V, the output still sinks current reliably to assert reset, making it compatible with mixed-voltage systems without level shifters.
What is the thermal resistance (RθJA) of TLV6703DSER in its WSON-6 package?
TLV6703DSER in the WSON-6 (DSE) package has a junction-to-ambient thermal resistance (RθJA) of 194.9°C/W. This value assumes standard JEDEC 2-layer board conditions and confirms suitability for operation at full specification in ambient temperatures up to +85°C without forced airflow or heatsinking.
How does TLV6703DSER behave during power-up?
TLV6703DSER incorporates power-on reset (V(POR) = 0.8 V) and undervoltage lockout (UVLO = 1.3–1.7 V). Below V(POR), OUT is high-impedance; between V(POR) and UVLO, OUT is forced low; above UVLO for ≥150 µs, OUT follows SENSE. This ensures deterministic reset assertion during startup.
