Texas Instruments TLV3701CDBVR

Overview

TLV3701CDBVR from Texas Instruments is a nanopower, single-channel comparator with push-pull CMOS output, designed for ultra-low-quiescent-current sensing in battery-powered systems. It draws only 560 nA supply current per channel, operates from 2.5 V to 16 V, supports input common-mode range from –0.1 V to V_CC + 5 V, and features reverse battery protection up to 20 V - enabling reliable voltage monitoring in portable medical devices and handheld instruments.

For engineers reviewing the TLV3701CDBVR datasheet, TLV3701CDBVR pinout, TLV3701CDBVR application, or TLV3701CDBVR equivalent, key selection criteria include its 560 nA supply current, rail-exceeding input range, push-pull output eliminating external pull-up resistors, –40°C to 125°C industrial-grade thermal performance, and SOT-23-5 packaging for space-constrained PCB layouts.

Technical Context

The TLV3701CDBVR implements a precision nanopower comparator core with internal power-on-reset (POR) logic that holds the output low for up to 3 ms during supply ramp-up, ensuring deterministic startup. Its input stage supports fail-safe operation: inputs remain high-impedance and undamaged even when biased up to 16 V while V_CC is unpowered or below 2.5 V.

It uses a push-pull CMOS output stage capable of sourcing and sinking ≥50 µA, delivering rail-to-rail logic-compatible swing without external components. Propagation delay is 16 µs (typ.) at 50 mV overdrive and 12 V supply, with hysteresis tightly controlled at 1–5 mV (typ.) across temperature.

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage allowed on TLV3701CDBVR pins?

The TLV3701CDBVR supports input voltages from –0.1 V to V_CC + 5 V, with absolute maximum ratings permitting up to 16 V on IN+ or IN− regardless of V_CC level. This over-the-rail capability is confirmed in Section 6.1 (Absolute Maximum Ratings) and Section 7.4.1.2 (Fail-Safe Inputs) of the SLCS137E datasheet. The device remains undamaged and functional even when V_CC is unpowered.

Does TLV3701CDBVR require an external pull-up resistor on its output?

No, TLV3701CDBVR does not require an external pull-up resistor because it features a push-pull CMOS output stage. As stated in the "Features" section and verified in Figure 5-1 and Section 8.2.2, the output actively drives both high and low states - sourcing and sinking ≥50 µA - eliminating the need for external passive components and reducing system power consumption.

What is the typical propagation delay of TLV3701CDBVR at 5 V supply?

At 5 V supply and 50 mV input overdrive, TLV3701CDBVR exhibits a typical propagation delay of 16 µs for both high-to-low and low-to-high transitions, as specified in Table 6-8 (Switching Characteristics) of the SLCS137E datasheet. Delay increases to 34 µs (PLH) and 45 µs (PHL) at 10 mV overdrive, confirming predictable timing behavior across operating conditions.

Can TLV3701CDBVR operate from a 2.5 V supply across the full commercial temperature range?

Yes, TLV3701CDBVR is fully specified for operation from 2.5 V to 16 V over the 0°C to 70°C commercial temperature range, as documented in Section 6.3 (Recommended Operating Conditions). Electrical characteristics including supply current (560 nA typ.), input offset voltage (5000 µV max), and propagation delay remain valid at 2.5 V, enabling use in coin-cell and single-alkaline applications.

How does the power-on-reset (POR) function behave in TLV3701CDBVR?

TLV3701CDBVR incorporates an internal POR circuit that holds the OUT pin low for up to 3 ms after V_CC crosses 1.5 V during power-up, as detailed in Section 7.3.1.1 and Figure 7-1. This ensures a known output state at startup, preventing spurious MCU interrupts or relay actuation - critical in safety-aware portable systems using TLV3701CDBVR.
