Product details
Overview
TPS3710QDSERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade voltage detector IC with wide input supply range (1.8V–18V), adjustable threshold down to 400mV, ±1.0% over-temperature threshold accuracy, 5.5µA typical quiescent current, and open-drain output rated to 18V - used for precision undervoltage monitoring in engine control units and ADAS power rails.
For engineers reviewing the TPS3710QDSERQ1 datasheet, TPS3710QDSERQ1 pinout, TPS3710QDSERQ1 application, or TPS3710QDSERQ1 equivalent, key selection criteria include its 1.5mm × 1.5mm WSON-6 package, built-in 5.5mV hysteresis, –40°C to +125°C junction temperature rating, and ability to monitor voltages above VDD via external resistor divider.
Technical Context
The TPS3710QDSERQ1 implements a high-accuracy comparator with internal 400mV reference and programmable threshold via external resistor divider on the SENSE pin. It operates across 1.8V–18V VDD and supports monitoring of rails up to 6.5V at SENSE independent of supply voltage.
Its open-drain OUT pin sinks up to 40mA and tolerates pull-up voltages up to 18V, enabling direct interface with reset/enable inputs of MCUs, FPGAs, and DC-DC controllers. Built-in hysteresis (5.5mV typ.) and low propagation delay (18µs HL / 29µs LH) ensure noise-immune, fast response to voltage faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 18V - powers directly from automotive battery or industrial 12V/15V rails without LDO pre-regulation. |
| Threshold Accuracy | ±1.0% over –40°C to +125°C - ensures reliable reset assertion across full automotive temperature range. |
| Quiescent Current | 5.5µA typical - enables always-on monitoring in battery-backed systems with minimal standby drain. |
| Hysteresis | 5.5mV typical - suppresses false triggering from rail noise or slow voltage recovery transients. |
| Output Type | Open-drain, 18V-rated - allows flexible pull-up to any logic rail (e.g., 3.3V, 5V, or 12V) independent of VDD. |
| Propagation Delay | 18µs (HL), 29µs (LH) - provides deterministic timing for system-level fault response and sequencing. |
| Input Bias Current | ±25nA max - permits use of high-value resistor dividers (e.g., >100kΩ) without significant threshold error. |
Pinout & Package
TPS3710QDSERQ1 is housed in a 1.5mm × 1.5mm, 6-pin WSON (DSE) package with wettable flanks, RoHS-compliant NIPDAUAG finish, and MSL Level-2 moisture sensitivity rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 1.8V–18V; requires local 0.1µF ceramic decoupling capacitor for stable operation. |
| SENSE | Monitoring input | High-impedance comparator input (0–6.5V range); sets detection threshold via external resistor divider. |
| OUT | Open-drain output | Sinks up to 40mA; must be pulled up externally; compatible with 18V logic interfaces. |
| GND (Pins 1, 3, 5) | Ground reference | All three pins must be connected to system ground; improves thermal dissipation and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive ambient temperatures (–40°C to +125°C) and ESD robustness (HBM ±2.5kV, CDM ±1kV). |
| Adjustable threshold from 400mV | Enables precise undervoltage detection for any rail ≥0.4V using two external resistors - no trimming required. |
| 18V-tolerant open-drain output | Eliminates level-shifting circuitry when interfacing with higher-voltage enable/reset inputs (e.g., 12V MCU reset). |
| Low 5.5µA quiescent current | Supports permanent connection to battery-supplied rails without compromising system standby time. |
| Built-in 5.5mV hysteresis | Prevents chatter during slow-rising/falling voltage transitions - no external hysteresis components needed. |
Applications
| Engine Control Unit (ECU) Power Monitoring | ADAS Camera Module Supply Supervision |
|---|---|
Use Scenario: Continuous monitoring of 12V battery-derived rail powering microcontroller and CAN transceiver in engine bay. IC Role / Device Role / Timing Role: Voltage detector asserting active-low reset signal when rail drops below 10.8V (–10% tolerance). Use Value: Prevents MCU lockup or CAN bus corruption during cold cranking or alternator failure by triggering controlled restart. |
Use Scenario: Supervising 5V DC-DC output supplying image sensor and ISP in rear-view camera module. IC Role / Device Role / Timing Role: Detects undervoltage condition on 5V rail and asserts reset to ISP before corrupted frame capture occurs. Use Value: Eliminates visual artifacts or black screen by ensuring clean power-up sequence after brownout recovery. |
| Industrial PLC I/O Module Rail Detection | Automotive Infotainment SoC Power Sequencing |
Use Scenario: Monitoring isolated 24V field power rail feeding digital I/O channels in factory automation controller. IC Role / Device Role / Timing Role: Threshold set to 21.6V (–10%) via resistor divider; drives fault LED and disables outputs on undervoltage. Use Value: Enables safe shutdown of actuator drivers before logic supply collapses, preventing unintended motion. |
Use Scenario: Coordinating power-good signaling between PMIC and application processor in head unit. IC Role / Device Role / Timing Role: Monitors 1.1V core rail and asserts enable signal only after stable voltage is confirmed for ≥150µs. Use Value: Guarantees SoC enters boot sequence only after all critical supplies meet specification - avoids boot failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809E33DBVR | Fixed 3.3V threshold; 1.6V–6V supply range; 0.5% accuracy; 2.5µA IQ; SOT-23-3 package. | Limited to low-voltage rails; no adjustable threshold; unsuitable for >6V monitoring or automotive temp range. | Select when monitoring fixed 3.3V logic rails in non-automotive applications where size and ultra-low IQ are prioritized. |
| MAX6326LT29D3+T | Fixed 2.93V threshold; 1.0V–5.5V supply; ±1.5% accuracy; 1.6µA IQ; SC70-3 package; no AEC-Q100 rating. | Not qualified for automotive use; narrower supply range; lower accuracy; no 18V-tolerant output. | Consider only for cost-sensitive consumer electronics with benign thermal environments and fixed-threshold needs. |
Compared with TLV809E33DBVR and MAX6326LT29D3+T, the TPS3710QDSERQ1 uniquely combines automotive qualification, wide 1.8V–18V operation, adjustable sub-400mV threshold capability, and 18V-tolerant output - making it the only viable option for high-reliability, multi-rail automotive voltage supervision.

FAQ
What is the minimum detectable voltage threshold for TPS3710QDSERQ1?
The TPS3710QDSERQ1 has an internal reference of 400mV and supports adjustable thresholds down to 400mV using an external resistor divider on the SENSE pin. With appropriate resistor selection, it can reliably detect undervoltage conditions on rails as low as 0.4V - verified across –40°C to +125°C with ±1.0% accuracy.
Can TPS3710QDSERQ1 monitor a voltage higher than its own VDD supply?
Yes. The SENSE pin accepts input voltages up to 6.5V regardless of VDD, and the device supports monitoring rails exceeding VDD (e.g., 12V rail while powered from 3.3V) using an external resistor divider. The TPS3710QDSERQ1's architecture isolates the sense path from supply limitations, enabling flexible multi-rail supervision.
What is the maximum sink current capability of the TPS3710QDSERQ1 output?
The TPS3710QDSERQ1 OUT pin is specified to sink up to 40mA while maintaining VOL ≤ 250mV (at VDD = 5V, IO = 5mA). Absolute maximum rating is 40mA, and performance is guaranteed across temperature and supply voltage - enabling direct drive of LEDs, optocouplers, or reset inputs without external buffering.
Does TPS3710QDSERQ1 require an external hysteresis network?
No. The TPS3710QDSERQ1 integrates 5.5mV typical hysteresis internally, eliminating the need for external components. This built-in hysteresis stabilizes the output against noise-induced glitches on the monitored rail and ensures clean, chatter-free transitions during slow voltage recovery - verified in typical characteristics plots across temperature and supply conditions.
What package type and footprint does TPS3710QDSERQ1 use?
TPS3710QDSERQ1 uses the 1.5mm × 1.5mm, 6-pin WSON (DSE) package with wettable flanks. Its pinout is VDD (Pin 2), SENSE (Pin 4), OUT (Pin 6), and GND on Pins 1, 3, and 5. The package supports standard reflow profiles (MSL Level-2, 260°C peak) and is optimized for space-constrained automotive PCB layouts.
