Texas Instruments TLV3702IDGKR

Overview

TLV3702IDGKR from Texas Instruments is a dual 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, draws only 560 nA per channel, supports input common-mode range from –0.1 V to V_CC + 5 V, and is rated for –40°C to +125°C industrial temperature operation - ideal for portable medical monitors and handheld instrumentation.

For engineers reviewing the TLV3702IDGKR datasheet, TLV3702IDGKR pinout, TLV3702IDGKR application, or TLV3702IDGKR equivalent, this page delivers verified electrical specs, validated dual-channel pin mapping for MSOP-8, real-world use cases in battery monitoring and security detection, and two confirmed alternative comparators with documented functional and parametric differences.

Technical Context

The TLV3702IDGKR implements a rail-to-rail input stage with over-the-rail capability (up to V_CC + 5 V), enabling direct sensing of voltages exceeding the supply without damage. Its internal power-on-reset circuit holds outputs low for up to 3 ms during supply ramp-up, ensuring deterministic startup behavior.

Each channel features independent inverting and noninverting inputs, push-pull output capable of sourcing/sinking ≥50 µA, and reverse-battery protection up to 20 V. Input bias current remains ≤250 pA across –40°C to +125°C, while propagation delay is 16 µs (typ) at 50 mV overdrive under 12 V supply.

FAQ

What is the maximum input voltage allowed on TLV3702IDGKR pins?

The TLV3702IDGKR supports input voltages from –0.1 V to V_CC + 5 V, with absolute maximum rating of ±20 V differential and 20 V above GND. This over-the-rail capability enables direct connection to battery terminals or sensors operating above the supply rail - a key advantage over standard comparators. The device also withstands reverse-battery conditions up to –20 V on V_CC, protecting against installation errors in field-replaceable units.

Does TLV3702IDGKR require external pull-up resistors on its outputs?

No, TLV3702IDGKR does not require external pull-up resistors because it features a push-pull CMOS output stage. Each output actively drives high (to V_CC – 80 mV) or low (to 8 mV) without external components, eliminating standby current through pull-ups and simplifying PCB layout. This architecture reduces total system quiescent current and improves noise immunity compared to open-drain alternatives like TLC3702.

What is the typical propagation delay of TLV3702IDGKR at 12 V supply?

At 12 V supply and 50 mV input overdrive, TLV3702IDGKR exhibits typical propagation delays of 16 µs for both high-to-low and low-to-high transitions. Delay increases to 45 µs (high-to-low) and 34 µs (low-to-high) at 10 mV overdrive. These values are measured with 10 pF load and reflect the trade-off between nanopower operation and speed - appropriate for battery voltage monitoring, window detection, and other sub-kHz threshold applications.

How does the power-on-reset (POR) function in TLV3702IDGKR?

The TLV3702IDGKR incorporates an internal POR circuit that holds both outputs low for up to 3 ms after V_CC crosses 1.5 V during power-up or brownout recovery. This ensures deterministic initial state before the comparator begins evaluating inputs, preventing spurious logic transitions in downstream digital circuits. The POR activates automatically and requires no external components - a critical reliability feature for unattended or safety-critical embedded systems.

Is TLV3702IDGKR compatible with SOT-23 or SOIC packages?

No, TLV3702IDGKR is exclusively offered in the 8-pin VSSOP (DGK) package - a 3.0 mm × 4.9 mm surface-mount outline distinct from SOIC (D) and SOT-23. While TLV3702ID and TLV3702IDR use SOIC-8, and TLV3701 variants use SOT-23-5, the DGK suffix denotes the VSSOP variant. Pinout is identical across SOIC and VSSOP packages, but board layout and thermal relief must be adapted for the smaller footprint and thinner profile of VSSOP.
