Product details
Overview
TLV3701CD from Texas Instruments is a single-channel nanopower 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 rail-to-rail input range (–0.1V to VCC + 5V), consumes only 560 nA per channel, and is rated for 0°C to 70°C commercial temperature range.
For engineers reviewing the TLV3701CD datasheet, TLV3701CD pinout, TLV3701CD application, or TLV3701CD equivalent, key selection criteria include its 560 nA supply current, 5 mV max input hysteresis, 45 µs high-to-low propagation delay at 10 mV overdrive, reverse battery protection up to 20V, and SOT-23-5 package compatibility with space-constrained portable designs.
Technical Context
The TLV3701CD implements a proprietary input stage enabling over-the-rail operation - inputs tolerate up to VCC + 5V without damage or latch-up, even when unpowered. Its internal power-on-reset (POR) holds the output low for ≤3 ms during supply ramp-up, ensuring deterministic startup behavior.
It uses a push-pull CMOS output stage eliminating external pull-up resistors, supports single-supply operation down to 2.5V, and integrates ESD protection (HBM TBD V) and reverse-battery protection up to 20V, making it suitable for harsh or miswired battery interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 560 nA per channel - enables multi-year battery life in coin-cell–powered monitoring circuits |
| Input common-mode range | –0.1 V to VCC + 5 V - allows direct sensing of voltages exceeding supply rail (e.g., battery voltage monitoring) |
| Propagation delay (PHL) | 45 µs at 10 mV overdrive - defines minimum detectable transient duration in slow-varying signals |
| Input offset voltage | 5000 µV max at 25°C - sets absolute threshold accuracy limit in precision level-detection applications |
| Hysteresis voltage | 2.8 mV typical - provides noise immunity against ~3 mV input ripple without external feedback |
| Output type | Push-pull CMOS - eliminates need for external pull-up, reducing BOM count and standby power in open-drain–incompatible systems |
| Reverse battery protection | Up to 20 V - prevents damage during incorrect battery insertion in consumer medical or handheld instruments |
Pinout & Package
TLV3701CD is packaged in a 5-pin SOT-23 (DBV) case measuring 2.9 mm × 2.8 mm, optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | CMOS push-pull output | Drives logic-high or logic-low actively; no external pull-up required |
| 2 - GND | Analog/digital ground reference | Must be connected to system ground plane; serves as return path for input bias and output current |
| 3 - IN+ | Noninverting input | Accepts signal up to VCC + 5 V; high-impedance node (≤250 pA bias current) |
| 4 - IN− | Inverting input | Accepts reference or inverted signal; same over-rail capability and impedance as IN+ |
| 5 - VCC | Positive supply rail | Supports 2.5–16 V single supply; internal POR activates below 1.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Nanopower operation | 560 nA supply current enables >10-year operation on CR2032 in wake-on-threshold systems |
| Over-the-rail input stage | Inputs functional at –0.1 V to VCC + 5 V - eliminates level-shifting for battery voltage monitoring above VCC |
| Integrated power-on reset | 3 ms output hold-low during VCC ramp ensures glitch-free startup in microcontroller-wake applications |
| Reverse battery protection | Withstands –20 V on VCC while GND is referenced - protects against accidental reverse polarity in field-deployed devices |
| Fail-safe inputs | Inputs remain high-impedance and undamaged even when VCC = 0 V - simplifies power sequencing in multi-rail systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701CDBV | Identical electrical specs; same SOT-23-5 package but supplied on mini-reel (250 pcs) with T suffix | No functional difference; differs only in packaging format and reel quantity | Select TLV3701CDBV for prototyping or low-volume production requiring smaller reels. |
| TLV3701ID | Same architecture and pinout; rated for –40°C to 125°C industrial temperature range vs. 0°C to 70°C | Suitable for automotive cabin modules or industrial sensors exposed to wider thermal cycling | Choose TLV3701ID when operating ambient exceeds 70°C or requires extended temperature qualification. |
Compared with TLV3701CDBV, TLV3701CD offers identical performance in commercial-temperature applications but ships in standard reel quantities; compared with TLV3701ID, it trades extended temperature range for lower cost and qualification overhead in consumer-grade portable designs.

FAQ
What is the maximum input voltage the TLV3701CD can withstand without damage?
The TLV3701CD supports an absolute maximum input voltage of VCC + 5 V (with VCC ≤ 16 V) or 20 V - whichever is smaller - as specified in Absolute Maximum Ratings. This over-the-rail capability allows direct connection to battery terminals or sensor outputs exceeding the supply rail, and remains valid even when VCC = 0 V due to fail-safe input design.
Does the TLV3701CD require an external pull-up resistor on its output?
No, the TLV3701CD does not require an external pull-up resistor because it features a push-pull CMOS output stage. The output actively drives both high (to within 80 mV of VCC) and low (to within 8 mV of GND) states, enabling direct interface with CMOS logic inputs and eliminating standby current through external resistors - a key advantage over open-drain comparators.
What is the typical propagation delay of the TLV3701CD at 12 V supply?
At VCC = 12 V, the TLV3701CD exhibits a typical high-to-low propagation delay (tPHL) of 16 µs with 50 mV input overdrive and 45 µs with 10 mV overdrive, as shown in Figure 6-13 of the datasheet. Low-to-high delay (tPLH) is 16 µs (50 mV) and 34 µs (10 mV). These values are measured into 10 pF load with 100 mV step input.
Can the TLV3701CD operate from a 2.5 V supply across its full temperature range?
Yes, the TLV3701CD is specified for 2.5 V to 16 V single-supply operation across its commercial temperature range (0°C to 70°C). At 2.5 V, it maintains full functionality including 560 nA supply current, over-the-rail inputs, and push-pull output drive - confirmed in Recommended Operating Conditions (Section 6.3) and Electrical Characteristics (Section 6.7).
How does the power-on-reset (POR) circuit affect TLV3701CD output behavior during startup?
The TLV3701CD internal POR circuit holds the output low for up to 3 ms after VCC crosses 1.5 V during power-up, ensuring a known state before the comparator becomes active. This prevents spurious interrupts or false triggers in MCU-wake applications. Once VCC exceeds the minimum operating voltage and the POR timeout expires, the output reflects the true differential input state.
