Texas Instruments TLV3701ID

Overview

TLV3701ID from Texas Instruments is a nanopower, single-channel comparator with push-pull CMOS output, designed for ultra-low-quiescent-current signal threshold detection in battery-powered systems. It operates from 2.7V to 16V supply, features –0.1V to V_CC + 5V input common-mode range, draws only 560 nA per channel, and is rated for –40°C to +125°C industrial temperature operation.

For engineers reviewing the TLV3701ID datasheet, TLV3701ID pinout, TLV3701ID application, or TLV3701ID equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated SOT-23 pin functions, and two confirmed alternative comparators for low-power sensing applications where supply current, over-rail input tolerance, and industrial-grade thermal stability are critical selection criteria.

Technical Context

The TLV3701ID implements a rail-to-rail input stage enabling operation with inputs up to 5V above V_CC, supported by internal ESD clamps and reverse-battery protection up to 20V. Its push-pull output eliminates external pull-up resistors and ensures fast, deterministic logic-level transitions without bus contention.

An integrated Power-On Reset (POR) circuit holds the output low for ≤3 ms during power ramp-up until V_CC exceeds 1.5V, ensuring known startup state. Input bias current remains below 1 pA in low common-mode region (0V to V_CC – 1V), rising to ~55 nA when inputs exceed V_CC.

FAQ

What is the maximum input voltage allowed on TLV3701ID pins?

The TLV3701ID supports an input common-mode voltage range from –0.1V to V_CC + 5V, with absolute maximum ratings permitting up to 20V differential input and 16V input voltage independent of supply. This means IN+ or IN− can safely reach 16V even when V_CC is unpowered or at 2.7V-enabling direct high-side battery sensing without external protection circuitry. The TLV3701ID's fail-safe input architecture ensures no damage occurs under these conditions.

Does TLV3701ID require an external pull-up resistor on its output?

No, TLV3701ID does not require an external pull-up resistor because it features a push-pull CMOS output stage capable of actively driving both high and low logic states. When the output is high, it sources current up to 2 µA with VOH ≥ V_CC – 80 mV; when low, it sinks up to 50 µA with VOL ≤ 80 mV. This eliminates BOM cost, board space, and leakage paths associated with open-drain comparators-making TLV3701ID ideal for ultra-low-power designs where every nanoamp counts.

Can TLV3701ID operate from a 2.5V supply?

TLV3701ID is specified for a minimum supply voltage of 2.7V over the full –40°C to +125°C industrial temperature range. While the datasheet lists 2.5V as the lower limit for commercial-grade variants (TLV3701CD), the I-suffix version TLV3701ID requires ≥2.7V to guarantee all electrical characteristics-including propagation delay, input offset, and output drive-across its entire operating temperature range. Operating below 2.7V may result in undefined behavior or degraded performance.

How does the Power-On Reset (POR) function in TLV3701ID?

The TLV3701ID integrates an internal Power-On Reset circuit that holds the OUT pin low for up to 3 ms after V_CC crosses 1.5V during power-up. This ensures a known, stable output state before the comparator begins responding to input signals-critical for preventing false triggers in wake-on-event systems. The POR remains active during brown-out conditions and resets upon each valid V_CC ramp, making TLV3701ID reliable in energy-harvesting and intermittently powered applications.

Is TLV3701ID pin-compatible with other comparators in the TLV370x family?

No, TLV3701ID is not pin-compatible with TLV3702 or TLV3704 due to differing channel counts and package footprints: TLV3701ID uses a 5-pin SOT-23, while TLV3702ID uses an 8-pin MSOP and TLV3704ID uses a 14-pin TSSOP. However, all TLV370x devices share identical electrical behavior, supply ranges, and functional pin definitions (e.g., IN+, IN−, V_CC, GND, OUT), enabling consistent schematic symbol reuse and firmware logic across single/dual/quad configurations when board layout permits rework.
