Product details
Overview
TLV3702QDRG4Q1 from Texas Instruments is an AEC-Q100 qualified dual nanopower comparator with push-pull CMOS outputs, 560nA per channel supply current, rail-to-rail input range (–0.1V to 16V), and operation from 2.7V to 16V supply - designed for voltage monitoring in automotive battery management and always-on sensor nodes.
For engineers reviewing the TLV3702QDRG4Q1 datasheet, TLV3702QDRG4Q1 pinout, TLV3702QDRG4Q1 application, or TLV3702QDRG4Q1 equivalent, this page delivers verified technical context, automotive-grade thermal and ESD specifications, push-pull output drive capability, reverse-battery protection up to 18V, and validated alternative comparators for low-power sensing designs.
Technical Context
The TLV3702QDRG4Q1 integrates two independent nanopower comparators sharing a single 2.7V–16V supply, each featuring fail-safe inputs tolerant of –0.1V to 16V regardless of V+, internal 2.8mV hysteresis, and Power-On Reset that holds outputs low for ≤2ms during power ramp-up. Its over-the-rail input stage enables direct high-side voltage sensing without level-shifting.
Each channel uses a push-pull CMOS output capable of sourcing/sinking ≥2µA at VOH = (V+) – 0.08mV and VOL = 8mV (IO = 2µA), eliminating external pull-ups. Reverse battery protection guards against –18V transients on V+ while maintaining functionality across –40°C to 125°C.

Applications
| Battery Voltage Monitor | Engine Bay Temperature Threshold Detector |
|---|---|
|
Use Scenario: Monitoring 12V lead-acid battery voltage across cold-cranking, charging, and sleep states in ADAS ECUs. IC Role / Device Role / Timing Role: Dual comparator performs undervoltage lockout (IN1±) and overvoltage alert (IN2±) with independent thresholds. Use Value: Push-pull outputs directly drive MCU GPIOs or enable/disable power rails; 560nA current avoids parasitic drain during vehicle sleep mode. |
Use Scenario: Detecting coolant or oil temperature excursions beyond safe limits using NTC thermistor divider networks. IC Role / Device Role / Timing Role: One channel compares thermistor voltage to fixed reference; second channel provides hysteresis-based latch for alarm persistence. Use Value: Input common-mode range (–0.1V to 16V) accommodates thermistor dividers referenced to 12V; failsafe inputs survive transient spikes during ignition. |
| Door Intrusion Detection Sensor | Start-Stop System Supervision |
|
Use Scenario: Latching open/closed state of door switches or capacitive touch sensors in body control modules. IC Role / Device Role / Timing Role: Comparator converts mechanical switch closure into clean digital signal; internal hysteresis rejects contact bounce. Use Value: 2.8mV hysteresis prevents false triggers from EMI; 560nA supply current allows integration into ultra-low-power wake-up circuits. |
Use Scenario: Validating battery health before engine restart in 48V mild-hybrid start-stop systems. IC Role / Device Role / Timing Role: Dual-channel configuration monitors both battery voltage and alternator output simultaneously to confirm readiness. Use Value: 16V max input range covers alternator surge transients; reverse-battery protection safeguards against jump-start misconnections. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702QDRQ1 | No G4 suffix; identical electrical specs, same SOIC-8 package, same AEC-Q100 qualification | Same automotive use cases; differs only in tape-and-reel packaging (2500 vs. 2500 pcs/reel) and marking (3702Q1 vs. 3702Q1) | Select TLV3702QDRQ1 if standard TI shipping configuration suffices; TLV3702QDRG4Q1 offers G4-grade Pb-free finish compliance. |
| TLV3402QDRG4Q1 | Lower supply current (470nA/ch), same 2.7V–16V range, but open-drain output - requires external pull-up | Suitable for wired-OR bus monitoring or I²C-compatible alert lines; not for direct MOSFET gate drive | Choose TLV3402QDRG4Q1 only when open-drain topology is required; TLV3702QDRG4Q1 preferred for push-pull simplicity and lower system component count. |
Compared with TLV3702QDRQ1, TLV3702QDRG4Q1 adds G4 Pb-free finish compliance without functional change; versus TLV3402QDRG4Q1, it trades 90nA higher supply current for integrated push-pull drive - reducing BOM count and enabling direct logic interfacing.

FAQ
What is the maximum input voltage the TLV3702QDRG4Q1 can tolerate?
The TLV3702QDRG4Q1 accepts input voltages from –0.1V to 16V on both IN+ and IN– pins, independent of the V+ supply voltage. This over-the-rail capability allows direct sensing of battery voltage or other signals exceeding V+, and the device survives reverse-battery conditions up to –18V on V+ - confirmed in Section 6.1 Absolute Maximum Ratings and Section 7.4.1.2 Fail-Safe Inputs of the SGLS154F datasheet.
Does the TLV3702QDRG4Q1 have internal hysteresis, and what is its value?
Yes, the TLV3702QDRG4Q1 includes internal hysteresis of 2.8mV typical (1mV to 5mV min/max), as specified in Section 6.4 Electrical Characteristics under VHYS. This hysteresis reduces sensitivity to noise in automotive environments and eliminates the need for external positive feedback networks when implementing threshold detection - directly supporting reliable voltage monitoring in noisy under-hood applications.
Can the TLV3702QDRG4Q1 drive a MOSFET gate directly?
Yes, the TLV3702QDRG4Q1's push-pull CMOS output can source and sink current - delivering VOH = (V+) – 0.08mV and VOL = 8mV at 2µA load - making it suitable for driving low-capacitance MOSFET gates in low-speed power control circuits. However, for high-Ciss loads or fast switching, external buffering is recommended; the datasheet cautions against shorting outputs to rails at >12V due to thermal risk.
Is the TLV3702QDRG4Q1 pin-compatible with the non-automotive TLV3702?
No - while TLV3702QDRG4Q1 and TLV3702 share identical pinout (SOIC-8), they differ in qualification: TLV3702QDRG4Q1 is AEC-Q100 Grade 1 qualified (–40°C to 125°C), with enhanced ESD (2000V HBM), reverse-battery protection, and automotive-specific test screening. The commercial TLV3702 lacks these qualifications and is not approved for automotive use per TI documentation.
What is the purpose of the Power-On Reset (POR) function in the TLV3702QDRG4Q1?
The TLV3702QDRG4Q1 incorporates an internal POR circuit that holds both outputs low for ≤2ms after V+ crosses 1.5V during power-up or power-down. This ensures deterministic initial state in safety-critical automotive systems - preventing undefined logic levels or spurious wake-up events - as detailed in Section 7.4.5 and Figure 7-3 of the SGLS154F datasheet.
