Product details
Overview
TLV1701AIDBVR from Texas Instruments is a single-channel, rail-to-rail input microPower comparator with open-collector output, 55 µA quiescent current, 560 ns low propagation delay (low-to-high), and operation across 2.2 V to 36 V supply range. It enables precise voltage detection in industrial power monitoring and overvoltage protection circuits.
For engineers reviewing the TLV1701AIDBVR datasheet, TLV1701AIDBVR pinout, TLV1701AIDBVR application, or TLV1701AIDBVR equivalent, key selection criteria include input offset voltage (±300 µV typ), temperature-stable propagation delay (±400–600 ns over –40°C to +125°C), rail-to-rail input common-mode range, open-collector output compatibility with 36 V pull-up, and SOT-23-5 package footprint constraints.
Technical Context
The TLV1701AIDBVR implements a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, supporting reliable signal detection near V+ and V–. Its open-collector output allows wired-OR configurations and flexible level-shifting up to 36 V above the negative supply.
Designed for wide-supply operation (±1.1 V to ±18 V or +2.2 V to +36 V), it maintains stable switching performance across temperature (–40°C to +125°C) with low input bias current (≤15 nA) and low input offset drift (±4 µV/°C typ), enabling accurate thresholding in noisy or thermally varying 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 direct interface with 24-V industrial buses and low-voltage battery systems. |
| Quiescent Current | 55 µA per channel; enables multi-year battery life in portable sensor nodes and always-on monitoring circuits. |
| Propagation Delay | 560 ns (low-to-high), 460 ns (high-to-low) at 100 mV overdrive; ensures fast response in overvoltage cutoff and zero-crossing detection. |
| Input Offset Voltage | ±300 µV (typ), ±5.5 mV (max over temp); provides <1% error in 3.3-V reference-based threshold detection. |
| Input Common-Mode Range | Includes both rails (V– to V+); allows direct sensing of signals at ground or near supply without external level-shifting. |
| Output Type | Open-collector; enables wired-OR logic, level translation up to 36 V above V–, and compatibility with I²C-style bus topologies. |
| Operating Temperature | –40°C to +125°C; qualified for under-hood automotive, motor control, and industrial PLC environments. |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 2.90 mm body, 0.95 mm max height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting input | Accepts rail-to-rail analog input; no phase inversion when driven beyond V+ or V–. |
| 2 - V– | Negative supply | Reference for internal circuitry; output can be pulled up to 36 V above this pin regardless of V+ value. |
| 3 - IN– | Inverting input | Differential input node; matched with IN+ for low offset and drift performance. |
| 4 - OUT | Open-collector output | Sinks current only; requires external pull-up resistor for logic-high state and voltage-level flexibility. |
| 5 - V+ | Positive supply | Primary power rail; supplies internal bias and input stage; supports up to +36 V absolute max. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables direct sensing of 0 V to 36 V signals without attenuation or clamping diodes. |
| 55 µA quiescent current | Reduces system power budget by >90% vs. legacy comparators, critical for energy-harvesting designs. |
| Stable propagation delay vs. temperature | Variation ≤100 ns across –40°C to +125°C, ensuring consistent timing in thermal cycling applications. |
| Open-collector output with 36-V tolerance | Allows single-output bus arbitration and interface with higher-voltage logic (e.g., 24-V PLC I/O). |
| Low input offset drift | ±4 µV/°C typical; minimizes thermal-induced threshold shift in precision window detectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1701AIDCKR | Same electrical specs; SC-70-5 package (1.25 mm × 2.00 mm), 0.1 mm lower profile than SOT-23-5. | Better suited for ultra-dense PCB layouts where board area is constrained more than height. | Select TLV1701AIDCKR when footprint area < 2.5 mm² is required and reflow profile accommodates smaller lead pitch. |
| LMV7215M5X | Higher quiescent current (80 µA), faster propagation (35 ns), but narrower supply range (2.7–5.5 V) and no rail-to-rail input. | Only viable for low-voltage, high-speed applications (e.g., 3.3-V logic monitoring), not industrial 24-V systems. | Choose LMV7215M5X only if speed >400 ns is mandatory and supply is strictly 3.3 V with buffered inputs. |
Compared with TLV1701AIDBVR, TLV1701AIDCKR offers identical functionality in a smaller footprint but with tighter assembly tolerances, while LMV7215M5X trades wide supply/rail-to-rail capability for raw speed-making TLV1701AIDBVR the sole choice for 2.2–36 V, rail-to-rail, microPower use cases.

FAQ
What is the maximum supply voltage rating for TLV1701AIDBVR?
The absolute maximum supply voltage for TLV1701AIDBVR is +40 V (or ±20 V). Operation beyond this risks permanent damage. The recommended operating range is +2.2 V to +36 V (or ±1.1 V to ±18 V), and all electrical specifications-including propagation delay and offset voltage-are guaranteed across this full range. Always use 0.1-µF ceramic bypass capacitors at the V+ and V– pins to ensure stability.
Does TLV1701AIDBVR support dual-supply operation?
Yes, TLV1701AIDBVR supports dual-supply operation from ±1.1 V to ±18 V. Its rail-to-rail input stage accepts common-mode voltages from V– to V+, and the open-collector output can be pulled up to any voltage ≤36 V above V–-enabling true bipolar signal comparison (e.g., ±12 V inputs) while maintaining low quiescent current (55 µA) and stable propagation delay across temperature.
Can TLV1701AIDBVR drive an LED directly?
No, TLV1701AIDBVR cannot drive an LED directly because its output is open-collector and only sinks current-it does not source. To drive an LED, connect the anode to a positive supply (≤36 V above V–) and the cathode to the OUT pin; the LED will illuminate when the comparator output is active (low). Ensure current-limiting resistance is sized for the LED forward voltage and desired brightness, respecting the 20 mA short-circuit sink limit.
What is the input offset voltage specification for TLV1701AIDBVR over temperature?
The input offset voltage for TLV1701AIDBVR is specified as ±5.5 mV maximum over the full operating temperature range of –40°C to +125°C. At +25°C, it is typically ±0.3 mV at 36 V supply and ±0.5 mV at 2.2 V supply. This tight offset, combined with ±4 µV/°C typical drift, ensures predictable threshold accuracy in temperature-critical applications like motor overtemperature detection.
Is TLV1701AIDBVR pin-compatible with other comparators in the TLV170x family?
TLV1701AIDBVR is pin-compatible only with other single-channel TLV1701 variants (e.g., TLV1701AIDCKR, TLV1701AIDRLR) in the same SOT-23-5, SC-70-5, or SOT553-5 packages. It is not pin-compatible with dual (TLV1702) or quad (TLV1704) versions due to differing pin counts and functions. For drop-in replacement, verify package code (DBV = SOT-23-5) and confirm layout matches the 5-pin gull-wing footprint.
