Product details
Overview
TLV1701AIDRLR 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 range. It enables precise voltage detection in industrial power monitoring and overvoltage protection circuits.
For engineers reviewing the TLV1701AIDRLR datasheet, TLV1701AIDRLR pinout, TLV1701AIDRLR application, or TLV1701AIDRLR equivalent, key selection considerations include its 300 µV typical input offset voltage, –40°C to +125°C temperature rating, SOT553-5 package footprint, and compatibility with pull-up voltages up to +36 V independent of supply rails.
Technical Context
The TLV1701AIDRLR implements a rail-to-rail input stage that maintains correct polarity even when inputs exceed supply rails-eliminating phase inversion. Its open-collector output supports wired-OR configurations and flexible level-shifting via external pull-up, enabling use in window comparators and high-side sensing.
Propagation delay remains stable across temperature (±40°C to +125°C) and supply voltage (2.2 V to 36 V), with measured tPLH = 560 ns and tPHL = 460 ns at 100 mV overdrive. Input bias current stays below 20 nA over full temperature range, supporting high-impedance threshold networks.

Use Scenario: Monitoring 24-V DC bus in PLC I/O modules to trigger shutdown if voltage exceeds 27 V or drops below 19 V. IC Role / Device Role / Timing Role: Single comparator compares bus voltage against precision reference; open-collector output drives latch circuit. Use Value: 55 µA supply current extends uptime in unpowered backup modes; rail-to-rail input captures full 0–24 V range without attenuation. |
Use Scenario: Detecting brownout in 12-V automotive body control module before MCU reset threshold is crossed. IC Role / Device Role / Timing Role: TLV1701AIDRLR compares scaled battery voltage to 1.225-V reference; output pulls down enable line of LDO regulator. Use Value: Stable 560 ns delay ensures clean assertion of reset signal without chatter; –40°C to +125°C rating covers cold-cranking to engine-off heat soak. |
| Zero-Crossing Detector | High-Side Current Sense Comparator |
|
Use Scenario: AC line synchronization in smart meter anti-tampering firmware using 50/60 Hz mains waveform. IC Role / Device Role / Timing Role: TLV1701AIDRLR detects polarity reversal of transformer-coupled AC signal referenced to isolated ground. Use Value: Rail-to-rail input accepts ±1.5 V signal directly; no external biasing needed; 300 µV offset minimizes timing jitter at zero-crossing point. |
Use Scenario: Detecting overcurrent in 48-V server power supply by comparing shunt voltage against 20-mV threshold. IC Role / Device Role / Timing Role: Single comparator senses differential voltage across high-side shunt; open-collector output interfaces with 3.3-V FPGA interrupt pin. Use Value: Output can be pulled to 3.3 V while device runs from 48 V - eliminates level-shifter IC and saves board space in dense PSU layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1701IDBVR | Same electrical specs; SC70-5 package (1.25 mm × 2.00 mm), 0.65 mm pitch, no exposed thermal pad | Less thermally efficient; suitable where board area > thermal performance priority | Select TLV1701IDBVR when legacy SC70 footprint compatibility is required and power dissipation < 15 mW |
| LMV7215M5X | Push-pull output (no external pull-up), 120 ns propagation delay, 80 µA IQ, 2.7–5.5 V supply only | Not suitable for >5.5 V or open-drain wired-OR topologies; faster but narrower supply range | Choose LMV7215M5X only for low-voltage, high-speed digital interface applications where pull-up elimination is critical |
Compared with TLV1701AIDRLR, TLV1701IDBVR offers identical functionality in a slightly larger but more widely adopted package, while LMV7215M5X trades supply flexibility and output configurability for speed and integration - making TLV1701AIDRLR the optimal choice for wide-supply, level-shifted, or thermally constrained industrial designs.

FAQ
What is the maximum allowable pull-up voltage for the TLV1701AIDRLR output?
The TLV1701AIDRLR open-collector output supports pull-up voltages up to +36 V above the negative supply rail (V–), regardless of the device's own V+ supply voltage. For example, with V– = 0 V (single-supply), VPULLUP may be as high as +36 V; with V– = –12 V, VPULLUP may reach +24 V. This capability enables direct interfacing with higher-voltage logic or relay drivers without level-shifting circuitry.
Does the TLV1701AIDRLR require external hysteresis for noise immunity?
The TLV1701AIDRLR does not include internal hysteresis and relies on external positive feedback (e.g., resistor network from OUT to IN+) to suppress noise-induced oscillation at threshold crossings. Typical hysteresis design uses Rh > 100 × Rp (pull-up resistor) to minimize threshold error. The device's low input bias current (<20 nA) ensures minimal hysteresis voltage error from leakage paths.
Can the TLV1701AIDRLR operate from a 1.8-V supply?
No. The TLV1701AIDRLR has a minimum specified supply voltage of +2.2 V (or ±1.1 V). Operation below 2.2 V is outside datasheet specifications and may result in undefined behavior, increased propagation delay, or failure to switch. For 1.8-V systems, consider TI's TLV3701 or similar nanopower comparators rated down to 1.4 V.
What is the thermal resistance (RθJA) of the TLV1701AIDRLR in its SOT553 package?
The TLV1701AIDRLR in the DRL (SOT553-5) package has a junction-to-ambient thermal resistance (RθJA) of 271.5°C/W under standard JEDEC test conditions (1s2p board). This value assumes no copper pour or thermal vias; adding a 1-inch² 2-oz copper pad with 4 thermal vias reduces effective RθJA to approximately 110°C/W in typical PCB layouts.
Is the TLV1701AIDRLR pin-compatible with other TLV170x family members?
No. The TLV1701AIDRLR is a single-channel device in 5-pin SOT553, while TLV1702 (dual) and TLV1704 (quad) use 8-pin and 14-pin packages respectively. Pin functions differ across channel count variants - for example, TLV1702 DGK has dedicated IN+/IN–/OUT pins per channel plus shared V+/V–, whereas TLV1701AIDRLR maps all functions to five pins. Direct substitution is not possible without PCB redesign.
