Texas Instruments TLV4062DBVR

Overview

TLV4062DBVR from Texas Instruments is a dual-channel, low-power comparator with integrated precision reference and push-pull outputs, designed for voltage monitoring in space-constrained systems. It operates from 1.5 V to 5.5 V, delivers 1% threshold accuracy over –40°C to +125°C, features 60 mV built-in hysteresis, and draws only 2 µA typical quiescent current - enabling reliable rail supervision in battery-powered electricity meters and thermostats.

For engineers reviewing the TLV4062DBVR datasheet, TLV4062DBVR pinout, TLV4062DBVR application, or TLV4062DBVR equivalent, this page provides verified functional context, validated package mapping (SOT-23-6), confirmed input threshold values (VIT+ = 1.194 V, VIT– = 1.134 V), output drive capability (push-pull, 0.25 V VOL @ 0.4 mA), and real-world implementation guidance for dual-rail monitoring and early-warning detection.

Technical Context

The TLV4062DBVR implements two independent comparators, each with internally trimmed rising (VIT+) and falling (VIT–) thresholds referenced to a stable on-die bandgap source. Its 60 mV hysteresis is fixed and non-adjustable, eliminating external feedback components while rejecting noise-induced false triggering on IN1 and IN2 inputs.

Each comparator asserts its respective push-pull output (OUT1/OUT2) low when its input falls below VIT– and high when it rises above VIT+, with propagation delays of 5.5 µs (rising) and 10 µs (falling) at 3.3 V supply. The device enters undefined output state below power-on-reset voltage (V(POR) = 0.8 V) and supports fault-tolerant input operation up to 5.5 V regardless of V+ level.

FAQ

What is the function of the VIT+ and VIT– thresholds in TLV4062DBVR?

The TLV4062DBVR uses VIT+ = 1.194 V and VIT– = 1.134 V as its rising and falling input thresholds. When an input voltage (IN1 or IN2) rises above VIT+, the corresponding output (OUT1 or OUT2) switches high; when it falls below VIT–, the output switches low. This 60 mV hysteresis prevents oscillation due to noise or slow-moving signals. These thresholds are factory-trimmed and guaranteed within ±1% over –40°C to +125°C, ensuring repeatable behavior in TLV4062DBVR-based monitoring circuits.

Can TLV4062DBVR monitor voltages higher than its supply voltage V+?

Yes - the TLV4062DBVR features fault-tolerant inputs that accept voltages from 0 V to 5.5 V regardless of V+ level, including when V+ = 0 V. This allows IN1 and IN2 to be connected directly to resistor dividers scaling higher system rails (e.g., 12 V, 24 V, or 48 V) without clamping diodes or level shifters. The internal ESD protection and input structure maintain high impedance and specified threshold accuracy even under these conditions, making TLV4062DBVR suitable for direct connection to unregulated power domains.

Does TLV4062DBVR require external hysteresis components?

No - TLV4062DBVR integrates 60 mV of precision hysteresis between VIT+ and VIT–, eliminating the need for external positive feedback resistors or capacitors. This built-in hysteresis is trimmed during manufacturing and remains stable across temperature and supply voltage. As a result, TLV4062DBVR simplifies board layout, reduces component count, and improves reliability in noisy environments such as motor drives or switch-mode power supplies - all without compromising on noise rejection performance.

How does the push-pull output of TLV4062DBVR differ from open-drain alternatives?

The TLV4062DBVR's push-pull outputs actively drive both high and low states without external components: OUT1/OUT2 source up to 0.4 mA at 0.8×V+ and sink up to 0.4 mA at ≤0.25 V. This contrasts with open-drain variants (e.g., TLV4082DBVR) that require external pull-up resistors to assert logic high. For TLV4062DBVR, this means direct compatibility with standard CMOS reset inputs, reduced bill-of-materials, faster rise times, and elimination of pull-up resistor selection errors - critical in compact, high-density designs where every mm² counts.

What is the startup behavior of TLV4062DBVR during power-up?

TLV4062DBVR includes a power-on-reset (POR) circuit that holds outputs in an undefined state until V+ exceeds V(POR) = 0.8 V. Once V+ crosses this threshold, a 570 µs startup delay begins before outputs become valid and responsive to input changes. During this interval, IN1/IN2 are sampled but OUT1/OUT2 remain inactive - preventing spurious resets or false alarms during supply ramp-up. This controlled initialization sequence ensures deterministic behavior in TLV4062DBVR-supervised systems, especially those with multiple asynchronous power domains.
