TPS3710QDSERQ1 - 18V Wide-VIN Automotive Voltage Detector | TI
N.º da peça: TPS3710QDSERQ1 ✓ AtivoTPS3710QDSERQ1 Visão geral
A voltage detector, also called a voltage supervisor or undervoltage monitor, belongs to the power-management IC hierarchy: voltage detector -> voltage supervisor -> power-management IC -> semiconductor. It is used in systems where an undervoltage condition can cause unreliable processor, memory, analog, or communication behavior. Unlike a general-purpose comparator, the TPS3710-Q1 family includes an automotive qualification level, separate supply and sense connections, and hysteresis intended to reject brief input glitches.
The TPS3710QDSERQ1 supports a wide 1.8V-to-18V operating range and includes a typical monitored threshold of 0.4V. The OUT signal is driven low when the voltage at SENSE drops below the negative-going trip threshold and returns high when the sensed voltage rises above the corresponding positive-going threshold. The output is open-drain, allowing the system designer to select the pull-up voltage and use wired-AND fault signaling. The automatic -40°C to +125°C junction-temperature specification makes the device suitable for harsh automotive environments.
The detector uses separate VDD and SENSE pins so the monitored voltage can be evaluated independently from the device supply. Its built-in hysteresis creates a defined separation between the falling and rising thresholds, reducing false output transitions when the monitored rail contains short disturbances. This feature is important in vehicle electrical systems, where load dumps, cold starts, and switching transients can produce short rail disturbances. The open-drain architecture also supports low-current design because the output can remain unasserted without continuously sourcing current.
Typical uses include automotive battery and 12V rail undervoltage detection, ECU power sequencing, body-control monitoring, infotainment supply supervision, and industrial or communications systems that require a compact, wide-input-range detector. In an automotive design, the monitored voltage may be connected to a vehicle rail while VDD is supplied from a regulated logic rail. The OUT pin can drive an external pull-up and feed a microcontroller or safety logic input.
The principal design consideration is to select the sensing resistor and feedback values so that the intended rail maps to the correct trip threshold without exceeding the device’s electrical limits. Place the SENSE connection away from high-current return paths to minimize ground bounce, and use the open-drain output with a pull-up voltage compatible with the receiving logic. The WSON package also requires a suitable exposed-pad thermal and PCB layout strategy.
This product page combines the verified manufacturer, distributor, and automotive ordering information with practical guidance on hysteresis, open-drain fault signaling, WSON layout, and the limited set of verified same-package alternatives. It is intended to help engineers evaluate whether the TPS3710QDSERQ1 matches the voltage range, fault-response polarity, temperature grade, package, and qualification requirements of a specific design.

Aplicações típicas
TPS3710QDSERQ1 é adequado para 6 aplicaçãos: Automotive Battery-Rail Supervision, ECU Power Sequencing and Reset, Automotive Body-Control Module, Infotainment Supply Monitoring, Industrial 24V-Control Input Supervision, Communications Equipment Power-Fault Flagging.
Automotive Battery-Rail Supervision
The TPS3710QDSERQ1 suits automotive battery-derived rail supervision because the Texas Instruments device supports a 1.8V-to-18V operating range and is specified to 125°C junction temperature. Place SENSE on the rail or a resistor-divider tap, then use the active-low open-drain OUT to signal an ECU when the monitored voltage crosses the programmed threshold. Built-in hysteresis helps prevent repeated fault events during short disturbances. Because the device is qualified under AEC-Q100 according to verified ordering information, it is a strong candidate for body, powertrain, and infotainment supply monitoring. The final design must still include the transient protection, filtering, and fault-response logic required by the vehicle platform.
Recomendado
ECU Power Sequencing and Reset
TPS3710QDSERQ1 can act as a power-state qualifier in an electronic control unit by monitoring a regulated rail and informing control logic through its active-low open-drain output. The 6-WSON package measures only 1.5 mm by 1.5 mm, helping preserve board area in distributed automotive electronics. Built-in hysteresis provides distinct falling and rising trip points, reducing ambiguity near the threshold. The output can be pulled up to the local logic supply and combined with other fault flags. Engineers should confirm threshold accuracy, response timing, and output behavior in the manufacturer datasheet before using the detector as the sole controller reset source.
Recomendado
Automotive Body-Control Module
The TPS3710QDSERQ1 is appropriate for compact body-control modules that must recognize an invalid supply condition before downstream logic becomes unstable. Its 18V maximum operating range supports automotive power environments, while the wide 1.5 mm by 1.5 mm WSON package limits footprint impact. Connect SENSE to a protected, filtered supply node and use OUT with an appropriate pull-up to report an undervoltage condition to the module controller. The integrated hysteresis helps the system reject brief rail movement without requiring a software-only delay. Automotive qualification and the -40°C to +125°C junction-temperature specification support harsh-temperature deployment, subject to the rest of the system’s protection and qualification requirements.
Recomendado
Infotainment Supply Monitoring
The TPS3710QDSERQ1 can monitor a vehicle infotainment supply and provide a hardware fault indication before the processor becomes dependent on an out-of-range rail. The device’s separate VDD and SENSE architecture allows the monitor itself to remain powered while checking a different voltage domain. Its open-drain output offers flexibility to select a local pull-up voltage and to aggregate multiple fault sources. The 0.4V typical threshold basis can be scaled through a resistor network when the monitored rail is higher, subject to the datasheet’s sense-node limits. The qualified wide-VIN family and compact package are useful advantages in space-constrained automotive entertainment units where board area and environmental robustness are important.
Recomendado
Industrial 24V-Control Input Supervision
Although the TPS3710QDSERQ1 is an automotive-qualified detector, its 18V operating ceiling makes it appropriate for industrial systems whose monitored signal is scaled below that limit. A resistive divider can translate a 24V control rail into a safe sense voltage, and OUT can report loss or improper sequencing to PLC or industrial-control electronics. The detector consumes the role of a simple hardware comparator by adding an automotive temperature profile, built-in hysteresis, and open-drain fault output. Because the monitored 24V rail is above the device’s verified operating range, the divider and transient protection must be designed independently, and the full analog signal path must remain within the manufacturer’s absolute-maximum limits.
Recomendado
Communications Equipment Power-Fault Flagging
TPS3710QDSERQ1 can provide a dedicated hardware fault flag in communication equipment that requires a deterministic undervoltage indication independent of the main processor. Monitoring a local supply through SENSE allows the detector to remain active during early startup or shutdown conditions. Its open-drain output can be wired to a system fault rail, while built-in hysteresis reduces false transitions around the programmed threshold. The compact 6-WSON footprint is valuable in dense line cards and embedded communication modules. Design verification should include startup behavior, pull-up selection, output timing, and the maximum voltage presented at SENSE; those detailed parameters were not available in the supplied search snippets and must be taken from the manufacturer datasheet.

Notas de projeto
Route the SENSE connection as a low-current Kelvin-style sense path and keep it away from high-current returns, motor-switching nodes, and connector return paths. Ground bounce on the monitored node can shift the apparent trip voltage and cause false assertions. If a resistor divider is used, place its upper and lower resistors close to the device and confirm that the SENSE pin voltage remains within the manufacturer’s absolute-maximum limits at every transient condition.
Use an external pull-up for the open-drain OUT signal and select a pull-up voltage compatible with the receiving logic. Do not rely on an internal pull-up unless the datasheet explicitly confirms one. Because the output can remain low during a fault, the pull-up resistor also determines the fault-state current. Validate the complete fault-signaling scheme at startup, shutdown, and reset so that the OUT state cannot produce an unintended logic transition.
The 6-WSON package is very small and requires attention to exposed-pad soldering and thermal management. Follow the manufacturer’s land pattern, solder-mask, paste, and reflow recommendations. Although a voltage detector normally dissipates little power, estimate worst-case dissipation using the maximum operating voltage and supply current from the datasheet, then confirm junction temperature using the package thermal data and actual PCB copper. Do not infer thermal performance from the package size alone.
Do not treat the same-package alternatives as automatic replacements. TPS3710DSER differs in ordering and qualification context, while TPS3700DSER may have different threshold, hysteresis, and timing characteristics. Before substituting either candidate, compare pin functions, threshold accuracy, output polarity, propagation delay, supply limits, absolute maximum ratings, temperature grade, and automotive qualification against the TPS3710-Q1 datasheet.
