Product details
Overview
TLV4062QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified dual comparator with integrated precision reference, push-pull outputs, 1.5 V to 5.5 V supply range, ±1% threshold accuracy over –40°C to +125°C, and 60 mV built-in hysteresis - used for rail monitoring and reset generation in automotive power management systems.
For engineers reviewing the TLV4062QDBVRQ1 datasheet, TLV4062QDBVRQ1 pinout, TLV4062QDBVRQ1 application, or TLV4062QDBVRQ1 equivalent, key selection factors include its automotive-grade temperature operation, ultra-low 2 µA quiescent current, SOT-23-6 package footprint, dual independent voltage detection capability, and push-pull output eliminating external pull-up resistors.
Technical Context
The TLV4062QDBVRQ1 implements two independent comparators with internal reference thresholds (VIT+ = 1.194 V, VIT– = 1.134 V) and fixed 60 mV hysteresis to reject noise-induced false triggering. Each input accepts 0 V to 5.5 V signals regardless of V+ voltage, enabling fault-tolerant monitoring of unpowered or ramping rails.
Its push-pull output stage drives high to V+ and low to GND without external components, supporting direct interface to MCU reset inputs or LDO enable pins. Startup delay is 570 µs after V+ crosses 1.5 V, and propagation delays are 5.5 µs (rising) and 10 µs (falling) at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - supports wide-input automotive systems including 12 V battery-derived rails via LDOs. |
| Quiescent Current | 2 µA (typ) - enables always-on voltage supervision in low-power vehicle modules without battery drain. |
| Threshold Accuracy | ±1% over –40°C to +125°C - ensures reliable trip points across full automotive ambient range. |
| Hysteresis | 60 mV - rejects transient noise on monitored rails without external feedback components. |
| Input Voltage Range | 0 V to 5.5 V independent of V+ - allows monitoring of unpowered or higher-voltage rails (e.g., 5 V bus while V+ = 3.3 V). |
| Output Type | Push-pull - eliminates need for external pull-up resistors, reducing BOM count and PCB area in space-constrained ECUs. |
| Propagation Delay | 5.5 µs (IN↑→OUT↑), 10 µs (IN↓→OUT↓) at 3.3 V - provides deterministic timing for system-level fault response. |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm body size), surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Power supply input | Accepts 1.5 V to 5.5 V; requires 0.1 µF ceramic bypass capacitor placed close to pin for stable operation. |
| 2 - OUT1 | Comparator 1 output | Push-pull: actively drives high to V+, low to GND; interfaces directly with MCU reset or regulator enable pins. |
| 3 - OUT2 | Comparator 2 output | Push-pull: identical behavior to OUT1; enables independent monitoring of two rails or early-warning + shutdown logic. |
| 4 - IN2 | Comparator 2 input | High-impedance analog input; configured via external resistor divider to detect specific voltage thresholds (e.g., 3.3 V or 5 V rails). |
| 5 - GND | Ground reference | Primary return path for supply and output currents; must be connected to system ground plane with low-inductance trace. |
| 6 - IN1 | Comparator 1 input | High-impedance analog input; electrically isolated from V+ supply - remains functional even when V+ = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation, HBM ESD H1C, CDM ESD C4B - meets automotive reliability requirements out-of-box. |
| Dual independent comparators | Enables simultaneous monitoring of two voltage rails (e.g., main 5 V and backup 3.3 V) or staged alert logic (early warning + hard reset). |
| Integrated 60 mV hysteresis | Eliminates need for external positive feedback networks - simplifies layout and improves noise immunity in noisy automotive environments. |
| Fault-tolerant inputs | IN1/IN2 accept 0 V to 5.5 V regardless of V+ level - supports monitoring of unpowered subsystems during cold-cranking or wake-up sequences. |
| Precision threshold trimming | VIT+ = 1.194 V ±1%, VIT– = 1.134 V ±1% - enables accurate overvoltage/undervoltage detection without calibration in production. |

Use Value: Enables graceful USB disconnect handling and memory retention during partial power loss, improving user experience and system robustness. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage-monitor comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4082QDBVRQ1 | Same family, open-drain outputs instead of push-pull; requires external pull-up resistors; supports 5.5 V output pull-up independent of V+. | Better suited for wired-OR configurations or level-shifting interfaces where outputs must interface with higher-voltage logic domains. | Select TLV4082QDBVRQ1 only if open-drain functionality is required; otherwise TLV4062QDBVRQ1 reduces component count. |
| LMV7235Q1MAX/NOPB | Single-channel, no integrated reference, no hysteresis, higher 35 µA quiescent current, wider 2.7 V–5.5 V supply range. | Lacks dual-channel integration and precision thresholding - requires external reference and hysteresis network for equivalent functionality. | Only consider LMV7235Q1MAX/NOPB if single-channel operation suffices and board space permits added passive components. |
Compared with TLV4082QDBVRQ1, TLV4062QDBVRQ1 eliminates pull-up resistors and simplifies layout; compared with LMV7235Q1MAX/NOPB, it delivers dual-channel supervision with integrated reference and hysteresis in a smaller solution size and lower power budget.

This specification is validated across all electrical parameters in the datasheet, including threshold accuracy, propagation delay, and quiescent current, ensuring reliable performance in under-hood and cabin-mounted automotive modules.
Does the TLV4062QDBVRQ1 require external hysteresis components?
No, the TLV4062QDBVRQ1 integrates 60 mV of precision hysteresis internally. This eliminates the need for external positive feedback resistors and ensures consistent noise rejection across temperature and supply voltage variations - a key advantage over general-purpose comparators like LMV7235Q1MAX/NOPB.
Can the TLV4062QDBVRQ1 monitor voltages higher than its V+ supply?
Yes. The IN1 and IN2 inputs of the TLV4062QDBVRQ1 accept 0 V to 5.5 V regardless of the V+ supply voltage. For example, it can monitor a 5 V rail while powered from a 3.3 V supply - enabling flexible voltage domain supervision without level shifters or additional regulators.
What is the typical quiescent current of the TLV4062QDBVRQ1?
The TLV4062QDBVRQ1 draws 2 µA typical quiescent current at 3.3 V and 25°C, with a maximum of 5.8 µA over the full –40°C to +125°C temperature range. This ultra-low power consumption makes it suitable for always-on automotive subsystems such as telematics and remote keyless entry receivers.
How does the TLV4062QDBVRQ1 differ from the TLV4082QDBVRQ1?
The TLV4062QDBVRQ1 features push-pull outputs that drive high to V+ and low to GND, eliminating external pull-up resistors.
