Product details
Overview
TLV3702IDGKRG4 from Texas Instruments is a dual nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-constrained systems. It draws only 560 nA per channel, operates from 2.5 V to 16 V, supports input common-mode voltage up to VCC + 5 V, and is rated for –40°C to +125°C industrial temperature range - ideal for portable medical monitors and handheld instrumentation.
For engineers reviewing the TLV3702IDGKRG4 datasheet, TLV3702IDGKRG4 pinout, TLV3702IDGKRG4 application, or TLV3702IDGKRG4 equivalent, key selection criteria include quiescent current (560 nA/ch), rail-overlapping input range (–0.1 V to VCC + 5 V), push-pull output drive capability, reverse-battery protection (up to 20 V), and MSOP-8 packaging compatibility with space-constrained PCB layouts.
Technical Context
The TLV3702IDGKRG4 implements a precision bipolar input stage enabling over-the-rail operation and fail-safe inputs that remain high-impedance even when unpowered. Its internal power-on-reset circuit holds outputs low for ≤3 ms during supply ramp-up, ensuring deterministic startup behavior without external reset circuitry.
It features a dedicated push-pull output stage eliminating need for external pull-up resistors, and includes integrated ESD clamps and power-supply overvoltage protection. Input bias current remains below 250 pA across its full operating range, supporting high-impedance sensor interfacing without significant loading error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current per channel | 560 nA typical - enables multi-year battery life in always-on monitoring applications |
| Input common-mode range | –0.1 V to VCC + 5 V - allows direct sensing of signals exceeding supply rail (e.g., battery voltage monitoring) |
| Supply voltage range | 2.5 V to 16 V single supply - supports wide input sources including Li-ion, alkaline, and industrial rails |
| Input offset voltage | 250 µV typical - ensures accurate threshold detection with minimal calibration overhead |
| Propagation delay (high-to-low) | 45 µs typical at 10 mV overdrive - balances speed and power efficiency for low-frequency event detection |
| Output type | Push-pull CMOS - drives logic directly without pull-up resistor, reducing BOM count and leakage paths |
| Operating temperature | –40°C to +125°C - qualified for harsh environments including automotive cabin and industrial field equipment |
Pinout & Package
TLV3702IDGKRG4 is housed in an 8-pin VSSOP (DGK) package measuring 3.0 mm × 4.9 mm, optimized for high-density PCB layouts while maintaining thermal performance (RθJA = 163.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull output for comparator channel 1 - sinks or sources current to drive logic or LED directly |
| 2 | 1IN− | Inverting input for channel 1 - accepts analog signals up to VCC + 5 V with <250 pA bias current |
| 3 | 1IN+ | Noninverting input for channel 1 - used for reference or signal comparison with same over-rail capability |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to minimize noise coupling |
| 5 | 2IN+ | Noninverting input for channel 2 - independent of channel 1, enabling dual-threshold or window-comparator configurations |
| 6 | 2IN− | Inverting input for channel 2 - supports differential or single-ended sensing on second channel |
| 7 | 2OUT | Push-pull output for comparator channel 2 - electrically isolated from channel 1 output |
| 8 | VCC | Positive supply pin - accepts 2.5 V to 16 V; requires local 0.1 µF ceramic decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Reverse battery protection | Withstands up to 20 V reverse polarity on VCC - prevents damage during incorrect battery installation in portable devices |
| Fail-safe inputs | Inputs remain high-impedance and undamaged even when VCC = 0 V - eliminates sequencing constraints in multi-rail systems |
| Power-on reset (POR) | Internal POR holds both outputs low for ≤3 ms during power-up - guarantees known initial state without external circuitry |
| Over-the-rail input stage | Accepts inputs up to VCC + 5 V or 16 V (whichever is smaller) - enables direct battery voltage monitoring without level-shifting |
| Ultra-small VSSOP-8 package | 3.0 mm × 4.9 mm footprint - saves >50% board area vs. SOIC-8 while maintaining thermal reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDR | Same silicon, SOIC-8 package (4.9 mm × 6.0 mm) - larger footprint, higher RθJA (116.7°C/W) | Preferred where manual soldering or legacy board compatibility is required; less suitable for ultra-dense layouts | Select TLV3702IDR if board rework or through-hole prototyping is needed; TLV3702IDGKRG4 preferred for volume production with pick-and-place. |
| TLV3602IDGKR | Lower supply current (320 nA/ch), but reduced input voltage range (0 V to VCC) and no over-rail capability | Suitable for lower-power applications where input signals stay within rails; lacks reverse-battery protection | Choose TLV3602IDGKR only when absolute minimum current dominates design - sacrifice over-rail sensing and robustness. |
Compared with TLV3702IDR and TLV3602IDGKR, TLV3702IDGKRG4 uniquely combines VCC + 5 V input tolerance, reverse-battery protection, and industry-leading 560 nA/ch consumption in the smallest VSSOP-8 package - making it optimal for next-generation portable and industrial edge sensors requiring both precision and resilience.

FAQ
What is the maximum input voltage allowed on TLV3702IDGKRG4 pins?
The TLV3702IDGKRG4 supports input voltages from –0.1 V to VCC + 5 V, with an absolute maximum rating of 16 V or VCC + 5 V (whichever is smaller). This over-the-rail capability allows direct connection to battery terminals or other signals exceeding the supply rail - a key advantage for battery monitoring and sensor front-ends where level-shifting would add complexity and power loss.
Does TLV3702IDGKRG4 require external pull-up resistors on its outputs?
No, TLV3702IDGKRG4 does not require external pull-up resistors because it features a push-pull CMOS output stage capable of actively driving both high and low logic states. This eliminates standby current through pull-up resistors, reduces component count, and improves noise immunity - especially valuable in ultra-low-power designs where every nanoamp matters.
Can TLV3702IDGKRG4 operate with a 2.5 V supply?
Yes, TLV3702IDGKRG4 is fully specified down to 2.5 V single-supply operation across its entire industrial temperature range (–40°C to +125°C). At 2.5 V, it maintains 560 nA per channel supply current, 250 µV typical input offset voltage, and functional push-pull output swing - enabling reliable operation from coin cells or low-dropout regulators in space-constrained systems.
How does the power-on-reset (POR) function in TLV3702IDGKRG4?
The TLV3702IDGKRG4 incorporates an internal POR circuit that holds both outputs low for ≤3 ms after VCC crosses 1.5 V during power-up. This ensures a known, safe initial state without requiring external reset components - critical for systems where undefined comparator outputs could trigger false alarms or latch faults before firmware initialization completes.
Is TLV3702IDGKRG4 compatible with standard VSSOP-8 footprints and reflow profiles?
Yes, TLV3702IDGKRG4 uses the industry-standard DGK (VSSOP-8) package with 0.65 mm pin pitch and JEDEC-standard moisture sensitivity level (MSL) 2a. It is compatible with standard lead-free reflow profiles and automated SMT assembly processes - verified by Texas Instruments' qualification testing per JESD22-A110 and JESD22-A108.
