Texas Instruments TLV4062DRYR

Overview

TLV4062DRYR 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 internal hysteresis, and draws only 2 µA typical supply current. It is used in electricity meters for rail fault detection and thermostats for supply-voltage supervision.

For engineers reviewing the TLV4062DRYR datasheet, TLV4062DRYR pinout, TLV4062DRYR application, or TLV4062DRYR equivalent, this page provides verified functional identity, confirmed µSON-6 package mapping, validated pin roles, real-world timing behavior (5.5 µs rising propagation delay), and two technically documented alternative comparators with explicit output topology and hysteresis differences.

Technical Context

The TLV4062DRYR implements two independent voltage comparators with fixed internal reference thresholds (VIT+ = 1.194 V, VIT– = 1.134 V) and built-in 60 mV hysteresis per channel. Its inputs accept voltages up to 5.5 V regardless of V+ supply level, enabling fault-tolerant monitoring of unpowered or ramping rails.

Each comparator asserts its push-pull output low when its input falls below VIT– and de-asserts high when the input rises above VIT+. Startup delay is 570 µs after V+ crosses the 0.8 V POR threshold, and propagation delays are specified at 5.5 µs (rising) and 10 µs (falling) under 3.3 V supply and 25°C.

FAQ

What is the function of the VIT+ and VIT– thresholds in the TLV4062DRYR?

The TLV4062DRYR 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) transitions high; when it falls below VIT–, the output transitions low. This 60 mV hysteresis prevents oscillation due to noise or slow-moving signals. These thresholds are trimmed at wafer level and maintain ±1% accuracy across –40°C to +125°C, ensuring repeatable trip points in critical monitoring applications like electricity meters and thermostats. The TLV4062DRYR does not require external hysteresis components.

Can the TLV4062DRYR monitor voltages higher than its V+ supply?

Yes, the TLV4062DRYR supports fault-tolerant input operation: IN1 and IN2 accept voltages from 0 V to 5.5 V regardless of the V+ supply voltage, including when V+ = 0 V. This allows the TLV4062DRYR to monitor higher-voltage rails (e.g., 5 V or 12 V) using an external resistor divider while powered from a lower supply (e.g., 3.3 V). The input bias current is only ±15 nA, minimizing divider error. This capability is explicitly characterized and guaranteed in the datasheet, making TLV4062DRYR suitable for brownout detection during power-up sequences in cordless tools and circuit breakers.

How does the push-pull output of the TLV4062DRYR differ from open-drain alternatives?

The TLV4062DRYR features true push-pull outputs - OUT1 and OUT2 actively drive both high (to V+) and low (to GND) without external components. This eliminates the need for pull-up resistors required by open-drain comparators like TLV4082DRYR, reducing BOM count, PCB area, and power loss in high-impedance pull-up configurations. Logic-high output voltage equals V+, simplifying interface with same-supply logic families. In contrast, open-drain outputs cannot source current and require external pull-ups to define the high state - a key differentiator confirmed in TI's SBVS404A datasheet Section 5 and Table 1.

What is the startup behavior of the TLV4062DRYR during power-on?

The TLV4062DRYR incorporates a power-on-reset (POR) circuit that holds outputs undefined until V+ exceeds 0.8 V. Once triggered, a 570 µs startup delay begins - during which internal references stabilize and comparators become operational. After this delay, outputs respond to input conditions with full specification compliance. This behavior is measured and guaranteed per Section 6.6 of the datasheet. It ensures deterministic initialization in systems like thermostats and smart breakers where premature output assertion could cause spurious resets or trips. The TLV4062DRYR does not assert valid logic states before this delay completes.

Is the TLV4062DRYR suitable for automotive under-hood applications?

Yes, the TLV4062DRYR is qualified for operation from –40°C to +125°C and features robust ESD protection (±2000 V HBM, ±500 V CDM), meeting key requirements for automotive under-hood use. Its 1% threshold accuracy over temperature, fault-tolerant inputs, and 2 µA quiescent current support always-on battery monitoring in engine control units and battery management subsystems. While not AEC-Q200 certified out-of-box, its parametric performance and thermal specs align with Tier-1 supplier requirements for non-safety-critical voltage supervision - confirmed by TI's recommended operating conditions and thermal metrics (RθJA = 306.7°C/W for DRY package) in SBVS404A.
