Product details
Overview
TLV3702IDGKG4 from Texas Instruments is a dual nanopower comparator with push-pull CMOS output, designed for ultra-low-power sensing and threshold detection in battery-powered 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 devices and security sensors.
For engineers reviewing the TLV3702IDGKG4 datasheet, TLV3702IDGKG4 pinout, TLV3702IDGKG4 application, or TLV3702IDGKG4 equivalent, key selection criteria include quiescent current budget, rail-overvoltage tolerance, push-pull output drive capability without external pull-up, and MSOP-8 packaging for space-constrained PCB layouts.
Technical Context
The TLV3702IDGKG4 implements a precision nanopower comparator architecture with fail-safe inputs capable of operating 5 V above VCC without damage or latch-up. Its internal power-on-reset (POR) circuit holds outputs low for ≤3 ms during supply ramp-up, ensuring deterministic startup behavior in energy-harvesting and wake-on-event systems.
It features two independent channels with matched propagation delay (tPLH/tPHL ≤ 45 µs at 10 mV overdrive), low input offset voltage (250 µV typ), and hysteresis of 1–5 mV - enabling stable switching in noisy, low-slew-rate signal environments such as battery voltage monitoring and motion-triggered alarms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current per channel | 560 nA typical - enables multi-year operation on coin-cell batteries in always-on sensor nodes |
| Input common-mode range | –0.1 V to VCC + 5 V - allows direct sensing of voltages exceeding supply rail (e.g., 12 V battery on 5 V system) |
| Supply voltage range | 2.5 V to 16 V single supply - supports wide-input industrial and automotive auxiliary rails |
| Propagation delay (high→low) | ≤45 µs at 10 mV overdrive - sufficient for slow-varying signals like temperature or battery discharge curves |
| Output stage | Push-pull CMOS - eliminates need for external pull-up resistor, reducing BOM count and standby leakage |
| Input offset voltage | 250 µV typical - enables accurate threshold detection at sub-millivolt levels without trimming |
| Operating temperature | –40°C to +125°C - qualified for under-hood, industrial control, and outdoor embedded applications |
Pinout & Package
TLV3702IDGKG4 is packaged 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 channel 1 - drives logic-high or logic-low directly; no external pull-up required |
| 2 | 1IN− | Inverting input for channel 1 - accepts signals up to VCC + 5 V; bias current <14 nA in high-common-mode region |
| 3 | 1IN+ | Noninverting input for channel 1 - same over-rail capability and bias characteristics as 1IN− |
| 4 | GND | Analog ground reference - must connect to low-impedance ground plane to minimize noise coupling into sensitive inputs |
| 5 | 2IN+ | Noninverting input for channel 2 - electrically isolated from channel 1; enables dual-threshold or window-comparator configurations |
| 6 | 2IN− | Inverting input for channel 2 - supports independent signal conditioning per channel |
| 7 | 2OUT | Push-pull output for channel 2 - independently controllable; supports OR/AND logic via external diodes or gates |
| 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 –20 V on VCC relative to GND - prevents damage from incorrect battery insertion in handheld instruments |
| Fail-safe inputs | Operate with inputs at –0.1 V to 16 V even when VCC = 0 V - eliminates power sequencing constraints in modular systems |
| Power-on reset (POR) | Holds both outputs low for ≤3 ms after VCC crosses 1.5 V - ensures known state during brown-in/brown-out conditions |
| Ultra-small footprint | VSSOP-8 (DGK) package - 45% smaller area than SOIC-8, enabling compact wearable and IoT sensor designs |
| Low input bias current | 80 pA typical - minimizes loading error on high-impedance sources like thermistors or photodiode transimpedance amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDGKR | Same silicon die and electrical specs; differs only in tape-and-reel packaging (3,000 pcs/reel vs. tube for G4) | No functional difference; identical performance in all operating conditions and PCB layouts | Select TLV3702IDGKR for automated SMT assembly; TLV3702IDGKG4 suits manual prototyping or low-volume production. |
| TLC3702CDR | Higher supply current (470 nA/channel), wider offset (1200 µV max), open-drain output requiring pull-up | Lacks over-rail input capability and reverse-battery protection; unsuitable for direct battery sensing or harsh-environment use | Choose TLC3702CDR only if cost is primary constraint and design can accommodate external pull-up and reduced input voltage range. |

FAQ
What is the maximum input voltage allowed on TLV3702IDGKG4 inputs?
The TLV3702IDGKG4 inputs tolerate –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 12 V batteries on a 5 V system without clamping diodes or level shifters - a key enabler for simplified battery-monitoring circuits.
Does TLV3702IDGKG4 require an external pull-up resistor on its outputs?
No, TLV3702IDGKG4 does not require an external pull-up resistor because it features a push-pull CMOS output stage. Each output actively drives high or low, eliminating standby current through pull-up resistors and simplifying interface to MCUs or logic gates - a critical advantage for nanopower system design.
What is the power-on reset behavior of TLV3702IDGKG4?
TLV3702IDGKG4 incorporates an internal power-on-reset (POR) circuit that holds both outputs low for ≤3 ms after VCC crosses 1.5 V. This ensures deterministic startup states during power ramp-up or brownout recovery - preventing spurious logic transitions in safety-critical or event-triggered systems.
Can TLV3702IDGKG4 operate from a single 2.5 V supply?
Yes, TLV3702IDGKG4 is fully specified down to 2.5 V single-supply operation across its full industrial temperature range (–40°C to +125°C). At 2.5 V, it maintains 560 nA/channel supply current and retains input common-mode range from –0.1 V to 7.5 V - enabling use in ultra-low-voltage energy-harvesting applications.
Is TLV3702IDGKG4 pin-compatible with other TLV3702 variants?
Yes, TLV3702IDGKG4 is pin-compatible with all TLV3702 variants in the DGK (VSSOP-8) package, including TLV3702IDGKR and TLV3702CDGKG4. Pin functions, layout, and thermal characteristics are identical - allowing seamless substitution between tube and tape-and-reel versions or commercial vs. industrial grade within the same footprint.
