Product details
Overview
TLV1701AIDBVT 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 ±1.1 V to ±18 V or +2.2 V to +36 V supply. It enables precise voltage detection in industrial power supply monitoring and overvoltage protection circuits.
For engineers reviewing the TLV1701AIDBVT datasheet, TLV1701AIDBVT pinout, TLV1701AIDBVT application, or TLV1701AIDBVT equivalent, key selection criteria include its rail-to-rail input stage, stable propagation delay vs temperature, 300 µV typical input offset voltage, open-collector output compatible with up to +36 V pull-up, and SOT-23-5 package for space-constrained designs.
Technical Context
The TLV1701AIDBVT uses a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, enabling reliable threshold detection near V+ or GND. Its open-collector output supports wired-OR configurations and flexible level-shifting via external pull-up to voltages up to +36 V above the negative supply.
Specified across –40°C to +125°C, it delivers stable 460–560 ns propagation delay (tpHL/tpLH) with 100 mV input overdrive and maintains ≤±5.5 mV input offset voltage over temperature. Input bias current remains below 20 nA across full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.2 V to +36 V or ±1.1 V to ±18 V - supports wide-input industrial supplies and battery-powered systems without level-shifting. |
| Quiescent Current | 55 µA per channel - enables multi-year operation in always-on sensor monitoring and low-power supervisory circuits. |
| 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 power converters. |
| Input Offset Voltage | ±300 µV typical, ±5.5 mV max over –40°C to +125°C - enables accurate threshold setting in precision window and zero-crossing detectors. |
| Input Common-Mode Range | Rail-to-rail (V– to V+) - allows direct sensing of signals at ground or supply rail, critical for high-side current sensing and battery voltage monitoring. |
| Output Type | Open-collector - permits output pull-up to any voltage ≤+36 V above V–, enabling interface with 3.3 V, 5 V, or 24 V logic domains. |
| ESD Rating | ±2000 V HBM - meets industrial handling requirements without additional protection circuitry. |
Pinout & Package
SOT-23-5 (DBV) package: 1.60 mm × 2.90 mm body, 0.95 mm height, surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting input | Accepts analog input signal; rail-to-rail common-mode range enables direct connection to sensed node without attenuation. |
| 2 - V– | Negative supply | Connects to system ground (single-supply) or negative rail (dual-supply); reference for all internal circuitry. |
| 3 - IN– | Inverting input | Receives reference voltage or feedback signal; differential pair with IN+ determines output state. |
| 4 - OUT | Open-collector output | Sinks current only; requires external pull-up resistor to define logic-high level and interface voltage domain. |
| 5 - V+ | Positive supply | Provides operating power; supports up to +36 V, enabling direct use in 24 V industrial bus monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables detection of signals within 10 mV of V+ or V–, eliminating need for input resistive dividers in high-side sensing. |
| Stable propagation delay vs temperature | Variation <±10% from –40°C to +125°C - ensures consistent timing margins in automotive and industrial thermal environments. |
| Low input bias current | ≤20 nA over full temperature range - minimizes error in high-impedance reference divider networks and capacitive sensor interfaces. |
| Open-collector output with 36 V tolerance | Allows pull-up to 3.3 V, 5 V, 12 V, or 24 V logic while powered from lower supply - simplifies mixed-voltage system design. |
| Industrial temperature range | –40°C to +125°C operation - qualified for under-hood automotive, motor drive, and factory automation applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1701IDBVT | Same electrical specs but rated for –40°C to +105°C (not +125°C); 100 µA max IQ vs 75 µA max for TLV1701AIDBVT. | Not suitable for under-hood automotive or high-temp industrial enclosures requiring full 125°C operation. | Select TLV1701AIDBVT when extended temperature qualification and tighter quiescent current spec are required. |
| LMV7215M5X | Push-pull output (no external pull-up needed), 1.8 V min supply, but higher 85 µA IQ and only 125°C max junction temp (not ambient). | Lacks 36 V output tolerance; cannot interface directly with 24 V logic; unsuitable for high-side sensing with rail-to-rail input. | Choose LMV7215M5X only for low-voltage, push-pull–driven logic interfaces where 36 V output compatibility is unnecessary. |
Compared with TLV1701IDBVT and LMV7215M5X, TLV1701AIDBVT uniquely combines 125°C ambient rating, rail-to-rail input, 36 V-tolerant open-collector output, and sub-60 µA quiescent current - making it the only option qualified for harsh-environment industrial power supervision with minimal BOM count.

FAQ
What is the maximum supply voltage for TLV1701AIDBVT?
The absolute maximum supply voltage for TLV1701AIDBVT is +40 V (or ±20 V). However, the recommended operating range is +2.2 V to +36 V (or ±1.1 V to ±18 V). Operating beyond +36 V risks permanent damage and violates the device's specified functional limits; sustained use above +40 V will cause irreversible failure. Always include input protection if transient overvoltage is possible in the application.
Does TLV1701AIDBVT support dual-supply operation?
Yes, TLV1701AIDBVT supports true dual-supply operation from ±1.1 V to ±18 V. The V+ pin connects to the positive rail and V– to the negative rail; inputs and output swing relative to this bipolar reference. This configuration enables symmetric threshold detection in AC-coupled signal paths and is explicitly validated in the datasheet's Recommended Operating Conditions table.
Can TLV1701AIDBVT drive a 24 V logic input directly?
Yes - the open-collector output of TLV1701AIDBVT can be pulled up to +24 V (or up to +36 V above V–) using an external resistor. When V– is grounded, the output safely switches between 0 V (sinking) and 24 V (pulled high), enabling direct interface with 24 V PLC inputs or relay drivers without level-shifting circuitry.
What is the input offset voltage specification for TLV1701AIDBVT at 125°C?
The input offset voltage for TLV1701AIDBVT is guaranteed to be ≤±5.5 mV over the full operating temperature range of –40°C to +125°C. At +125°C specifically, typical offset remains near ±300 µV, but the worst-case bound is ±5.5 mV - a value confirmed in the Electrical Characteristics table under "TA = –40°C to +125°C" test condition.
Is a bypass capacitor required for stable operation of TLV1701AIDBVT?
Yes - TI recommends a 0.1 µF ceramic bypass capacitor placed as close as possible to the V+ and V– pins. This reduces supply noise coupling into the comparator's sensitive input stage and prevents false triggering, especially in noisy industrial environments. Layout guidelines in the datasheet emphasize low-ESR placement and direct connection to a solid ground plane.
