Product details
Overview
TLV3701QDBVRQ1 from Texas Instruments is an AEC-Q100 qualified nanopower comparator with push-pull CMOS output, 560 nA supply current per channel, –0.1 V to 16 V input common-mode range, and operation from 2.7 V to 16 V supply. It serves as a rail-to-rail input voltage threshold detector in automotive battery monitoring circuits.
For engineers reviewing the TLV3701QDBVRQ1 datasheet, TLV3701QDBVRQ1 pinout, TLV3701QDBVRQ1 application, or TLV3701QDBVRQ1 equivalent, key selection criteria include ultra-low quiescent current, reverse-battery protection up to 18 V, fail-safe over-rail inputs, and guaranteed operation across –40°C to 125°C.
Technical Context
The TLV3701QDBVRQ1 implements a high-voltage-capable input stage enabling operation with inputs up to 16 V independent of V+, and features internal hysteresis (1–5 mV typ) to suppress noise-induced switching. Its power-on reset circuit holds the output low for ~3 ms during supply ramp-up, ensuring deterministic startup behavior.
It uses a push-pull output stage capable of sourcing and sinking current without external pull-ups, supporting direct drive of MOSFET gates or LEDs. Input bias current remains below 1 pA in low common-mode region (0 V to V+ − 1 V), rising to ~55 nA when inputs exceed V+.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3701QDRQ1 | SOIC-8 package (vs. SOT-23-5); identical electrical specs and AEC-Q100 qualification | Requires larger PCB footprint and different layout; better thermal dissipation in high-ambient environments | Select when board space allows SOIC and higher θJA margin is needed |
| TLV3401QDBVRQ1 | Lower supply current (470 nA typ), same 2.7–16 V range, open-drain output (not push-pull) | Requires external pull-up for logic-high; unsuitable for driving capacitive loads or MOSFET gates directly | Select only if lowest possible current is critical and system already provides pull-up infrastructure |
Compared with TLV3701QDBVRQ1, TLV3701QDRQ1 offers identical performance in a larger SOIC package for easier assembly or thermal management, while TLV3401QDBVRQ1 trades push-pull drive capability for marginal current reduction-making TLV3701QDBVRQ1 optimal for space-constrained, direct-drive automotive sensing nodes.

FAQ
What is the maximum input voltage the TLV3701QDBVRQ1 can tolerate without damage?
The TLV3701QDBVRQ1 supports an absolute maximum input voltage of –0.3 V to 20 V per pin, with fail-safe operation up to 16 V over-rail (i.e., exceeding V+) and reverse-battery protection up to 18 V on supply pins. This allows direct connection to automotive battery rails without external clamping diodes or resistive dividers in most use cases.
Does the TLV3701QDBVRQ1 have internal hysteresis, and what is its typical value?
Yes, the TLV3701QDBVRQ1 includes internal hysteresis with a typical value of 2.8 mV and a specified range of 1–5 mV at 25°C. This built-in hysteresis stabilizes switching behavior in noisy environments such as automotive power domains, eliminating the need for external positive feedback networks in basic threshold-detection applications.
Can the TLV3701QDBVRQ1 operate with a single 3.3 V supply?
Yes, the TLV3701QDBVRQ1 operates from 2.7 V to 16 V, making it fully compatible with 3.3 V systems. At 3.3 V, it maintains 560 nA supply current, –0.1 V to 16 V input common-mode range, and push-pull output swing from near V− to within 80 mV of V+, enabling interoperability with 3.3 V microcontrollers and logic families.
How does the power-on reset (POR) function behave in the TLV3701QDBVRQ1?
The TLV3701QDBVRQ1 incorporates an internal POR circuit that holds the output low for approximately 3 ms after V+ crosses 1.5 V during power-up. This ensures a defined initial state in safety-critical automotive subsystems, preventing spurious outputs or undefined logic levels during supply ramp-up or brownout recovery sequences.
Is the TLV3701QDBVRQ1 pin-compatible with other comparators in the TLV370x-Q1 family?
TLV3701QDBVRQ1 is pin-compatible with TLV3701QDRQ1 in the same functional configuration (single comparator), differing only in package (SOT-23-5 vs. SOIC-8). It is not pin-compatible with dual-channel TLV3702 variants due to different pin counts and assignments. No other manufacturer's comparators share its exact 5-pin SOT-23 push-pull layout.
