Product details
Overview
TLV3702CDGKG4 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 voltages up to VCC + 5 V, and is rated for 0°C to 70°C commercial operation in an 8-pin VSSOP package.
For engineers reviewing the TLV3702CDGKG4 datasheet, TLV3702CDGKG4 pinout, TLV3702CDGKG4 application, or TLV3702CDGKG4 equivalent, key selection criteria include its rail-overdrivable inputs, reverse-battery-protected architecture, propagation delay under 50 µs at 10 mV overdrive, and compatibility with single-supply portable instrumentation requiring stable low-IQ performance.
Technical Context
The TLV3702CDGKG4 implements a precision nanopower comparator core with internal power-on-reset (POR) that holds outputs low for ≤3 ms during supply ramp-up. Its input stage enables fail-safe operation - inputs remain high-impedance and undamaged even when biased up to 16 V while VCC is unpowered or below 2.5 V.
It features a push-pull output stage eliminating external pull-up resistors, supports common-mode input range from –0.1 V to VCC + 5 V, and delivers typical input offset voltage of 250 µV with <3 µV/°C drift - enabling accurate threshold detection across temperature without trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current per channel | 560 nA typical - enables multi-year battery life in always-on monitoring circuits |
| Supply voltage range | 2.5 V to 16 V single supply - supports direct connection to Li-ion, 9 V, or 12 V systems |
| Input common-mode range | –0.1 V to VCC + 5 V - allows sensing above supply rail (e.g., battery voltage monitoring) |
| Propagation delay (high-to-low) | 45 µs typical at 10 mV overdrive - sufficient for slow-varying signals like temperature or battery SOC |
| Input offset voltage | 250 µV typical - ensures ≤1.25 mV error at 5× gain, suitable for 1% threshold accuracy |
| Output stage | Push-pull CMOS - eliminates need for external pull-up, reduces BOM count and standby leakage |
| Operating temperature | 0°C to 70°C - qualified for commercial-grade portable and consumer electronics environments |
Pinout & Package
TLV3702CDGKG4 is housed in an 8-pin VSSOP (DGK) package measuring 3.0 mm × 4.9 mm, optimized for space-constrained PCB layouts while maintaining thermal resistance RθJA = 163.9°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull output for channel 1 - drives logic-high or logic-low directly without external components |
| 2 | 1IN− | Inverting input for channel 1 - accepts signals up to VCC + 5 V with no damage or clamping |
| 3 | 1IN+ | Noninverting input for channel 1 - used with resistor dividers or references for precise threshold setting |
| 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; enables dual-threshold or window-comparator topologies |
| 6 | 2IN− | Inverting input for channel 2 - supports differential or single-ended sensing on second channel |
| 7 | 2OUT | Push-pull output for channel 2 - electrically isolated from 1OUT; supports independent logic-level signaling |
| 8 | VCC | Positive supply pin - requires local 0.1 µF ceramic decoupling placed within 2 mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Nanopower consumption | 560 nA per channel - extends battery life in coin-cell-powered devices beyond 10 years |
| Rail-overdrivable inputs | –0.1 V to VCC + 5 V input range - enables direct battery voltage monitoring without level-shifting |
| Reverse battery protection | Withstands –20 V on VCC relative to GND - prevents latch-up or damage from incorrect battery insertion |
| Power-on reset (POR) | 3 ms output hold-low during VCC ramp-up - guarantees known initial state in power-critical systems |
| Fail-safe input operation | Inputs functional and undamaged at 16 V even with VCC = 0 V - eliminates sequencing constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702CDR | Same die, SOIC-8 package (4.9 mm × 6.0 mm), tape-and-reel packaging | Requires larger PCB footprint; better thermal dissipation (RθJA = 116.7°C/W vs. 163.9°C/W) | Select TLV3702CDR for manual prototyping or higher-volume automated assembly where board space permits |
| TLV3702IDGKR | Industrial-grade variant (–40°C to 125°C), same VSSOP-8 package and electrical specs | Validated for automotive cabin modules or industrial sensors requiring extended temperature operation | Select TLV3702IDGKR when ambient operating temperature exceeds 70°C or long-term reliability at temperature extremes is required |
Compared with TLV3702CDGKG4, TLV3702CDR offers mechanical robustness and thermal margin at the cost of size, while TLV3702IDGKR provides identical form-factor performance across harsher environments - neither is pin-compatible with alternate packages, and both retain the same nanopower, rail-overdrivable, and push-pull advantages.

FAQ
What is the maximum input voltage allowed on TLV3702CDGKG4 pins?
The TLV3702CDGKG4 supports input voltages from –0.1 V to VCC + 5 V, with absolute maximum rating of ±20 V differential and 16 V above GND. This allows direct connection to unregulated battery rails or sensor outputs exceeding the supply voltage - a key enabler for battery voltage monitoring without external level-shifting circuitry.
Does TLV3702CDGKG4 require external pull-up resistors on its outputs?
No. TLV3702CDGKG4 features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pull-up resistors. This reduces component count, saves board space, and removes standby current paths - critical for maintaining nanopower operation in always-on systems.
What is the power-on behavior of TLV3702CDGKG4?
TLV3702CDGKG4 incorporates an internal power-on-reset (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 - preventing spurious logic transitions or false triggers in downstream microcontrollers or latching circuits during supply ramp-up.
Can TLV3702CDGKG4 operate from a single 2.5 V supply?
Yes. TLV3702CDGKG4 is fully specified from 2.5 V to 16 V single supply (or ±1.25 V to ±8 V dual supply). At 2.5 V, it maintains 560 nA per channel supply current, 250 µV typical input offset, and functional push-pull outputs - making it suitable for applications powered by single alkaline or lithium primary cells.
Is TLV3702CDGKG4 pin-compatible with other TLV370x variants?
TLV3702CDGKG4 shares identical pinout with all TLV3702 dual comparators in VSSOP-8 (DGK) package, including TLV3702IDGKR and TLV3702CDGKR. However, it is not pin-compatible with SOIC-8 (D) or PDIP-8 (P) variants due to different pad layouts and thermal pad configurations - PCB layout must match the DGK footprint precisely.
