Product details
Overview
TLV1701QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive microPower comparator with rail-to-rail inputs, open-collector output, 55 µA quiescent current, 560 ns propagation delay (low-to-high), and operation from 2.2 V to 36 V - used in overvoltage detection, window comparators, and system monitoring for automotive ECUs.
For engineers reviewing the TLV1701QDBVRQ1 datasheet, TLV1701QDBVRQ1 pinout, TLV1701QDBVRQ1 application, or TLV1701QDBVRQ1 equivalent, key selection criteria include input offset voltage (±3.5 mV typ), temperature stability (–40°C to +125°C), open-collector output compatibility with 36-V pull-up rails, and SOT-23-5 package suitability for space-constrained automotive PCBs.
Technical Context
The TLV1701QDBVRQ1 implements a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, enabling reliable high-side sensing. Its open-collector output supports wired-OR configurations and flexible level translation up to 36 V above the negative supply regardless of VS.
Designed for automotive Grade 1 operation, it maintains stable propagation delay (460–560 ns) across –40°C to +125°C and exhibits low input bias current (5–20 nA) and input offset voltage drift (±4–20 µV/°C), critical for precision threshold detection in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.2 V to 36 V (or ±1.1 V to ±18 V) - supports wide-input automotive battery systems including cold-crank and load-dump conditions. |
| Quiescent Current | 55 µA per channel - enables always-on monitoring without compromising battery life in automotive body control modules. |
| Propagation Delay | 560 ns (low-to-high), 460 ns (high-to-low) at 100-mV overdrive - ensures fast response for real-time fault detection in safety-critical subsystems. |
| Input Offset Voltage | ±3.5 mV (typ), ±5.5 mV (max over temp) - provides accurate voltage thresholding for undervoltage/overvoltage protection circuits. |
| Input Common-Mode Range | Rail-to-rail (V– to V+) - allows direct sensing of signals near ground or supply rails, e.g., battery voltage monitoring at 0 V reference. |
| Output Configuration | Open-collector - permits external pull-up to any voltage ≤36 V above V–, enabling interface with 3.3-V, 5-V, or 24-V logic domains. |
| ESD Rating (HBM) | ±2000 V - meets AEC-Q100-002 requirements for robustness in automotive assembly and field operation. |
Pinout & Package
SOT-23-5 package (1.60 mm × 2.90 mm body size), surface-mount, RoHS-compliant, MSL Level-2-260°C-1 year, marked "1701".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting input | Accepts analog input signal; rail-to-rail common-mode range enables direct connection to battery or sensor outputs without level-shifting. |
| 2 - V– | Negative supply rail | Reference node for single-supply (GND) or dual-supply (–VS) operation; output sink current flows through this pin. |
| 3 - IN– | Inverting input | Reference input for threshold comparison; used with resistive dividers to set precise trip points in voltage monitors. |
| 4 - OUT | Open-collector output | Requires external pull-up resistor; sinks current when asserted - compatible with 3.3-V, 5-V, or 24-V logic families and wired-OR bus architectures. |
| 5 - V+ | Positive supply rail | Primary power input; supports up to 36 V, enabling direct connection to automotive 12-V/24-V systems with transient tolerance. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Overvoltage Detection | Window Comparator |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1701AQDCKRQ1 | Same silicon, SC-70-5 package (1.25 mm × 2.00 mm); 3000-piece tape-and-reel; identical electrical specs and AEC-Q100 Grade 1 rating. | Preferred for ultra-dense layouts where 0.65-mm footprint reduction over SOT-23 is critical; thermal resistance higher (222.5°C/W vs. 233.1°C/W). | Select when board space is constrained and thermal margin permits slightly reduced power dissipation capability. |
| TLC3702-Q1 | Push-pull output (no external pull-up required); higher quiescent current (20 µA vs. 55 µA); faster propagation (120 ns); not rail-to-rail input. | Better for driving capacitive loads directly or interfacing with CMOS inputs; unsuitable for high-side sensing or wired-OR bus topologies. | Choose when low-latency push-pull drive is prioritized over input flexibility and ultra-low power consumption. |
Compared with TLV1701AQDCKRQ1, TLV1701QDBVRQ1 offers larger pad geometry for improved manufacturability and thermal performance; compared with TLC3702-Q1, it trades speed and output convenience for rail-to-rail input operation and 2.7× lower supply current - making it optimal for battery-sensitive, high-voltage automotive sensing.

FAQ
What is the maximum supply voltage rating for TLV1701QDBVRQ1?
The absolute maximum supply voltage for TLV1701QDBVRQ1 is 40 V (±20 V), but recommended operating range is 2.2 V to 36 V. Exceeding 40 V risks permanent damage. The device is rated for automotive load-dump transients up to 36 V, and its open-collector output can be pulled up to 36 V above V– regardless of VS. TLV1701QDBVRQ1 must be operated within these limits to ensure reliability and AEC-Q100 compliance.
Does TLV1701QDBVRQ1 support rail-to-rail input operation?
Yes, TLV1701QDBVRQ1 features a true rail-to-rail input stage with common-mode range from V– to V+, enabling accurate sensing of signals at or near ground and supply rails. This eliminates the need for external level-shifting components in applications like battery voltage monitoring or high-side current sensing. The device also prevents phase inversion when inputs exceed supply rails - a critical feature verified in TI's characterization data for TLV1701QDBVRQ1.
What is the typical propagation delay of TLV1701QDBVRQ1 and how does it vary with temperature?
TLV1701QDBVRQ1 has a typical propagation delay of 560 ns (low-to-high) and 460 ns (high-to-low) at 100-mV input overdrive. Characterization data shows stable delay across –40°C to +125°C, with minimal variation - critical for deterministic timing in automotive fault-detection circuits. The delay remains within 560 ±100 ns over full temperature range, as confirmed in Figure C012 of the TLV1701QDBVRQ1 datasheet.
Can TLV1701QDBVRQ1 be used in a dual-supply configuration?
Yes, TLV1701QDBVRQ1 supports dual-supply operation from ±1.1 V to ±18 V (i.e., total supply span up to 36 V). In dual-supply mode, V+ connects to +VS, V– connects to –VS, and inputs/output operate symmetrically around ground. The rail-to-rail input stage and open-collector output retain full functionality. TLV1701QDBVRQ1 is commonly deployed this way in automotive audio amplifiers and sensor signal conditioning circuits requiring bipolar signal handling.
What package type and marking does TLV1701QDBVRQ1 use?
TLV1701QDBVRQ1 uses the SOT-23-5 (DBV) package with nominal dimensions 1.60 mm × 2.90 mm. It is marked "1701" on the top surface. The device is RoHS-compliant, lead-finish NIPDAU, and rated MSL Level-2-260°C-1 year. This package is optimized for automated placement and reflow in automotive PCB assembly, and its thermal resistance (RθJA = 233.1°C/W) supports reliable operation in under-hood environments when properly heatsinked.
