Product details
Overview
TLV3701IDBVTG4 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 2.7V to 16V, draws only 560 nA supply current per channel, supports input common-mode voltage up to VCC + 5 V, and features reverse battery protection up to 20 V - enabling reliable use in portable medical monitors and handheld instrumentation.
For engineers reviewing the TLV3701IDBVTG4 datasheet, TLV3701IDBVTG4 pinout, TLV3701IDBVTG4 application, or TLV3701IDBVTG4 equivalent, key selection criteria include its 560 nA supply current, rail-exceeding input range (–0.1 V to VCC + 5 V), push-pull output eliminating external pull-ups, –40°C to 125°C industrial temperature rating, and SOT-23-5 packaging for space-constrained designs.
Technical Context
The TLV3701IDBVTG4 implements a precision nanopower comparator core with internal power-on-reset (POR) that holds output low for ≤3 ms during supply ramp-up. Its input stage supports fail-safe operation beyond the positive rail - inputs tolerate up to 16 V independent of VCC - and exhibit <1 pA bias current in low common-mode region (0 V to VCC – 1 V).
Propagation delay is overdrive-dependent: 34 µs (low-to-high) and 45 µs (high-to-low) at 10 mV overdrive (12 V, CL = 10 pF); rise/fall times are each 0.2 µs. Input offset voltage is 250 µV (typ), with 3 µV/°C drift and 1–5 mV hysteresis - enabling stable threshold detection without external hysteresis components in many low-speed applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 560 nA per channel - enables multi-year battery life in coin-cell–powered devices |
| Input common-mode range | –0.1 V to VCC + 5 V - allows direct sensing of voltages exceeding supply rail (e.g., battery voltage monitoring) |

| 2 - GND | Analog ground reference | Primary return path for input bias currents and output load; must connect to low-impedance ground plane |
| 3 - IN+ | Noninverting input | Accepts signal to be compared against IN–; supports common-mode range up to VCC + 5 V |
| 4 - IN– | Inverting input | Accepts reference or threshold voltage; same over-rail capability as IN+ |
| 5 - VCC | Positive supply rail | Single-supply input (2.7–16 V); powers internal bias, POR, and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Reverse battery protection | Withstands –20 V on VCC relative to GND - prevents damage from incorrect battery insertion in portable equipment |
| Fail-safe inputs | Inputs remain high-impedance and undamaged even when unpowered or at –0.1 V to 16 V - eliminates sequencing constraints |
| Power-on reset (POR) | Internal circuit holds OUT low for ≤3 ms during VCC ramp-up - ensures known initial state and avoids spurious outputs |
| Over-the-rail input stage | Operates with inputs up to 5 V above VCC - enables direct monitoring of battery voltage without level-shifting resistors |
| Ultra-small footprint | SOT-23-5 package (2.9 mm × 2.8 mm) - saves board area in wearables, sensor nodes, and compact medical devices |
Applications
| Portable Battery Monitoring | Consumer Medical Electronics |
|---|---|
Use Scenario: Real-time monitoring of lithium coin-cell or alkaline battery voltage in wireless glucose meters or pulse oximeters. IC Role / Device Role / Timing Role: Comparator detecting when battery voltage drops below 2.4 V to trigger low-battery alert. Use Value: 560 nA quiescent current extends usable battery life by >3× versus microamp-level comparators; push-pull output drives MCU interrupt pin directly. | Use Scenario: Threshold detection of ECG electrode contact impedance or temperature sensor output in home-use cardiac monitors. IC Role / Device Role / Timing Role: Single-ended comparator comparing analog sensor output to a stable 1.25 V reference (e.g., REF3312). Use Value: Input common-mode range extending to VCC + 5 V allows direct connection of high-impedance sensors without attenuation or buffering. |
| Security Detection Systems | Handheld Instruments |
Use Scenario: Tamper-detection circuit sensing unauthorized enclosure opening via microswitch or magnetic reed switch closure. IC Role / Device Role / Timing Role: Comparator converting mechanical switch state into clean digital logic signal for microcontroller input. Use Value: Fail-safe inputs tolerate floating or overvoltage conditions during switch bounce or ESD events; –40°C to 125°C rating ensures reliability in outdoor enclosures. | Use Scenario: Power-rail supervision in portable multimeters or thermal imagers with dual battery configurations. IC Role / Device Role / Timing Role: Monitoring main and backup supply rails to enable automatic source switchover or fault logging. Use Value: Reverse battery protection prevents latch-up during hot-swap battery replacement; 2.7 V minimum operating voltage supports operation down to near-end-of-life battery voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701CDBVT | Commercial-grade (0°C to 70°C) version with identical electrical specs and SOT-23-5 package | Limited to indoor, non-industrial environments; not rated for extended temperature cycling | Select TLV3701CDBVT only if ambient operating temperature remains within 0°C–70°C and cost sensitivity outweighs long-term reliability requirements |
| TLV3601DBVR | Higher speed (45 ns propagation delay), higher supply current (9 µA), same SOT-23-5 package and rail-exceeding inputs | Targeted at fast-response applications (e.g., overvoltage protection), not ultra-low-power monitoring | Choose TLV3601DBVR when response time <100 ns is mandatory and system can accommodate ~16× higher quiescent current |
Compared with TLV3701CDBVT, TLV3701IDBVTG4 provides guaranteed operation across –40°C to 125°C and tighter input offset drift control; versus TLV3601DBVR, it delivers 94% lower supply current at the cost of 700× slower propagation - making it optimal for battery longevity over speed.

FAQ
What is the maximum input voltage allowed on the IN+ and IN– pins of TLV3701IDBVTG4?
The TLV3701IDBVTG4 supports an input common-mode voltage range from –0.1 V to VCC + 5 V, with absolute maximum rating of ±20 V differential and up to 16 V on either input regardless of VCC. This over-rail capability enables direct sensing of battery voltages or other signals exceeding the supply rail without external clamping or level-shifting circuitry.
Does TLV3701IDBVTG4 require an external pull-up resistor on its output?
No, TLV3701IDBVTG4 does not require an external pull-up resistor because it features a push-pull CMOS output stage. The output actively drives both high (to VCC – 80 mV) and low (to 8 mV), eliminating standby current through external resistors and simplifying interface to CMOS logic or microcontroller GPIO pins.
What is the purpose of the Power-On Reset (POR) function in TLV3701IDBVTG4?
The internal Power-On Reset (POR) circuit in TLV3701IDBVTG4 holds the output low for up to 3 ms after VCC crosses 1.5 V during power-up or brownout recovery. This ensures a known, glitch-free initial state and prevents spurious triggering of downstream logic before the comparator's internal biasing stabilizes - critical for reliable system boot behavior.
Can TLV3701IDBVTG4 operate from a 2.5 V supply?
TLV3701IDBVTG4 is specified for minimum supply voltage of 2.7 V over the full –40°C to 125°C industrial temperature range. While some units may function at 2.5 V, TI guarantees performance only from 2.7 V onward; for 2.5 V operation, consider TLV3701CD variants (commercial grade, 0°C–70°C) which specify 2.5 V minimum.
How does the input bias current of TLV3701IDBVTG4 vary with common-mode voltage?
TLV3701IDBVTG4 exhibits <1 pA input bias current when inputs operate in the low common-mode region (0 V to VCC – 1 V), rising to ~55 nA when inputs exceed VCC (over-the-rail mode). This dual-region behavior preserves accuracy in precision reference comparisons while enabling robust overvoltage tolerance - verified across –40°C to 125°C.
