Product details
Overview
TLV3701IP from Texas Instruments is a nanopower, single-channel comparator with push-pull CMOS output, designed for ultra-low-quiescent-current sensing in battery-powered systems. It operates from 2.5V to 16V supply, features –0.1V to VCC + 5V input common-mode range, reverse battery protection up to 20V, and is rated for –40°C to 125°C industrial temperature operation.
For engineers reviewing the TLV3701IP datasheet, TLV3701IP pinout, TLV3701IP application, or TLV3701IP equivalent, this page delivers verified specifications, validated SOT-23 and PDIP package data, confirmed push-pull timing behavior, and real-world use cases in portable medical electronics and security detection systems.
Technical Context
The TLV3701IP implements a rail-to-rail input stage with fail-safe over-the-rail capability (inputs operable up to VCC + 5V or 16V absolute), enabling direct sensing of voltages exceeding the supply without damage. Its internal power-on-reset (POR) circuit holds the output low for ≤3 ms during VCC ramp-up, ensuring deterministic startup.
It uses a low-power bias architecture delivering only 560 nA per channel supply current at 25°C, with input offset voltage ≤5 mV (max), hysteresis of 1–5 mV, and propagation delays of 16–45 µs depending on overdrive - all specified across –40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 560 nA typical per channel - enables multi-year battery life in coin-cell–powered devices |
| Supply Voltage Range | 2.5V to 16V single supply - supports wide-input energy harvesting and 12V industrial rails |
| Input Common-Mode Range | –0.1V to VCC + 5V - allows direct monitoring of battery voltage or sensor signals above VCC |
| Output Type | Push-pull CMOS - eliminates need for external pull-up, reducing BOM count and standby power |
| Propagation Delay | 16 µs (high-to-low, 50 mV overdrive) - sufficient for slow-varying thresholds like battery SOC alerts |
| Input Offset Voltage | 5 mV max at 25°C - sets minimum detectable voltage difference in precision threshold applications |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial control, and outdoor security systems |
Pinout & Package
TLV3701IP is supplied in an 8-pin plastic DIP (PDIP) package measuring 10.2 mm × 9.4 mm, with through-hole mounting and industry-standard lead spacing. This package provides robust thermal performance (RθJA = 82.8°C/W) and mechanical stability for high-reliability industrial assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | CMOS push-pull output - drives logic-high or logic-low directly without external components |
| 2 | IN– | Inverting input - accepts analog signals up to VCC + 5V, with fail-safe operation even when VCC = 0V |
| 3 | IN+ | Noninverting input - same over-the-rail capability as IN–; used for reference or signal comparison |
| 4 | GND | Analog ground reference - must be connected to system ground plane for stable common-mode rejection |
| 5 | NC | No internal connection - electrically isolated; may be left unconnected or tied to GND for mechanical stability |
| 6 | NC | No internal connection - electrically isolated; no routing or loading required |
| 7 | VCC | Positive supply input - accepts 2.5V–16V; requires local 0.01 µF ceramic + 10 µF electrolytic decoupling |
| 8 | NC | No internal connection - electrically isolated; no functional impact if floating |
Key Features
| Feature | Design Value |
|---|---|
| Reverse battery protection | Withstands –20V input transients without latch-up or damage - critical for field-replaceable battery modules |
| Power-on reset (POR) | Holds OUT low for ≤3 ms during VCC ramp-up - prevents false triggers during power sequencing |
| Over-the-rail input stage | Accepts inputs up to 16V independent of VCC - enables direct 12V battery monitoring with 3.3V supply |
| Fail-safe inputs | Maintains high-Z state with ±10 mA max input current even when VCC = 0V - avoids backfeeding or signal corruption |
| Ultra-small quiescent current | 560 nA typical at 25°C - reduces average current draw below self-discharge rate of primary lithium cells |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701IDBV | SOT-23-5 package (2.9 mm × 2.8 mm); same electrical specs; lower RθJA (193.6°C/W) but higher thermal resistance than PDIP | Better suited for space-constrained PCBs; requires surface-mount assembly; lacks through-hole mechanical robustness | Select TLV3701IDBV for compact portable designs; choose TLV3701IP for manual prototyping, high-vibration environments, or legacy through-hole production lines. |
| TLV3401IP | 470 nA supply current (vs. 560 nA); identical pinout and package; 30 µs max tPHL at 10 mV overdrive (vs. 45 µs) | Marginally faster response and lower IQ - advantageous in battery-critical, high-sample-rate wake-up circuits | TLV3401IP offers measurable IQ and speed improvements; verify compatibility with existing layout due to identical PDIP footprint and function. |
Compared with TLV3701IP, TLV3701IDBV trades thermal performance and mounting flexibility for board area savings, while TLV3401IP delivers lower quiescent current and faster propagation - both retain full functional equivalence for threshold detection but differ in thermal, mechanical, and timing margins.

FAQ
What is the maximum input voltage the TLV3701IP can tolerate without damage?
The TLV3701IP supports input voltages from –0.1V to VCC + 5V, with absolute maximum ratings allowing up to 20V differential input and 16V absolute input voltage regardless of VCC. This over-the-rail capability enables direct sensing of 12V battery rails using a 3.3V supply, and reverse battery protection guards against –20V transients - all confirmed in Section 6.1 Absolute Maximum Ratings of the SLCS137E datasheet.
Does the TLV3701IP require an external pull-up resistor on its output?
No, the TLV3701IP features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for an external pull-up resistor. This reduces component count, saves board space, and cuts standby power consumption - a key advantage over open-drain comparators. The output delivers VOH ≥ VCC – 80 mV and VOL ≤ 8 mV under light load, as specified in Section 6.7 Electrical Characteristics.
What is the guaranteed operating temperature range for the TLV3701IP?
The TLV3701IP is an industrial-grade variant with a guaranteed operating free-air temperature range of –40°C to 125°C, as explicitly stated in Table 4-2 and Section 6.3 Recommended Operating Conditions. All key parameters - including supply current (ICC), input offset voltage (VIO), and propagation delay - are characterized across this full range, making it suitable for under-hood automotive, industrial control, and outdoor security applications.
How does the power-on-reset (POR) function behave on the TLV3701IP?
The TLV3701IP incorporates an internal POR circuit that holds the output low for ≤3 ms after VCC crosses 1.5V during power-up, ensuring predictable startup behavior. This prevents spurious output transitions during supply ramp-up and eliminates the need for external reset circuitry. The POR is active only during VCC transition and does not affect normal operation - details are provided in Section 7.3.1.1 and Figure 7-1 of the datasheet.
Can the TLV3701IP be used with a single 2.5V supply?
Yes, the TLV3701IP is fully specified for operation from 2.5V to 16V single supply, with recommended conditions and electrical characteristics validated at 2.5V (Section 6.3). At 2.5V, it maintains 560 nA typical supply current, –0.1V to 7.5V input common-mode range, and functional push-pull output - enabling use in ultra-low-voltage energy harvesting nodes and coin-cell–powered IoT sensors.
