Product details
Overview
TLV6700QDSERQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive window comparator IC with dual open-drain outputs, internal 400-mV reference, ±0.5% threshold accuracy at 25°C, 5.5 µA typical quiescent current, and 1.8 V to 18 V supply range-used for overvoltage/undervoltage monitoring in battery-supervised systems.
For engineers reviewing the TLV6700QDSERQ1 datasheet, TLV6700QDSERQ1 pinout, TLV6700QDSERQ1 application, or TLV6700QDSERQ1 equivalent, key selection considerations include its 125°C junction-rated thin SOT-23-6/WSON-6 packaging, built-in 5.5 mV hysteresis, 18-V output voltage rating independent of VDD, and dual-polarity input architecture enabling precise window detection without external references.
Technical Context
The TLV6700QDSERQ1 integrates two matched comparators sharing a trimmed 400-mV internal reference: INA+ drives OUTA low on undervoltage (VIT+ – VHYS), while INB– drives OUTB low on overvoltage (VIT+). Both outputs are open-drain, rated to 18 V, and support wired-OR fault signaling.
It operates across –40°C to 125°C with 1.0% max threshold accuracy over temperature, 150–450 µs start-up delay, and 1.3–1.7 V undervoltage lockout-ensuring deterministic behavior during power ramp-up and brownout conditions in automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 18 V - supports direct connection to 12-V automotive battery rails and low-power microcontroller domains. |
| Reference Voltage | 400 mV ±0.5% at 25°C - enables precise window thresholds via external resistor dividers without external reference ICs. |
| Threshold Accuracy | ±1.0% over –40°C to 125°C - ensures reliable undervoltage/overvoltage trip points across full automotive ambient range. |
| Quiescent Current | 5.5 µA typical - allows continuous monitoring in always-on vehicle modules without excessive battery drain. |
| Hysteresis | 5.5 mV typical - rejects noise-induced false triggering on noisy power rails like OBC or head unit supplies. |
| Output Rating | 18 V open-drain - permits pull-up to higher-voltage logic domains (e.g., 12-V CAN transceiver I/O) independent of VDD. |
| Propagation Delay | 18 µs (tPHL), 29 µs (tPLH) at 5 V - provides deterministic response timing for fault logging and system shutdown sequencing. |
Pinout & Package
TLV6700QDSERQ1 is packaged in thin SOT-23-6 (2.90 mm × 1.60 mm) and leadless WSON-6 (1.50 mm × 1.50 mm), both qualified per AEC-Q100 Grade 1. Pin functions are identical across packages; only physical orientation differs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA+ | Noninverting input (Comparator A) | Monitors rising-edge voltage drop below (VIT+ – VHYS) to assert OUTA low - used for undervoltage detection. |
| INB– | Inverting input (Comparator B) | Monitors falling-edge voltage rise above VIT+ to assert OUTB low - used for overvoltage detection. |
| OUTA | Open-drain output (Comparator A) | Sinks up to 40 mA; requires external pull-up; asserts low during undervoltage condition. |
| OUTB | Open-drain output (Comparator B) | Sinks up to 40 mA; requires external pull-up; asserts low during overvoltage condition. |
| VDD | Power supply input | Accepts 1.8–18 V; internal UVLO disables outputs below 1.3 V; decoupling capacitor required at pin. |
| GND | Analog ground reference | Common return for reference, inputs, and outputs; must be low-impedance path to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables simultaneous overvoltage and undervoltage monitoring on same rail using one IC - reduces BOM count vs discrete solutions. |
| Internal 400-mV reference | Eliminates need for external precision reference; 0.5% initial accuracy enables ±2.94% total window error with standard 1% resistors. |
| 18-V output voltage rating | Allows pull-up to 12-V or 18-V logic domains regardless of VDD - simplifies interface to high-side drivers or legacy automotive controllers. |
| Built-in 5.5-mV hysteresis | Rejects sub-10-µs transients per Figure 7-7 - prevents false trips during load dump or ignition switching events. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation with HBM ±2500 V / CDM ±1000 V ESD robustness - meets automotive functional safety requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6710QDSERQ1 | Wider 1.8–36 V supply range; 0.75% max threshold accuracy over temp; same pinout and function. | Preferred for 24-V commercial vehicle systems or 48-V mild-hybrid architectures requiring extended voltage headroom. | Select TLV6710QDSERQ1 when monitoring >18-V rails; otherwise TLV6700QDSERQ1 offers lower cost and identical performance at ≤18 V. |
| MAX9022AASA+ | Single 2.7–5.5 V supply; dual comparators with 1.22-V reference; no internal hysteresis; SO-8 package. | Limited to low-voltage infotainment subsystems; requires external hysteresis resistors and reference bypassing. | Choose MAX9022AASA+ only for non-automotive 3.3-V designs where AEC-Q100 is unnecessary and board space allows SO-8 footprint. |
Compared with TLV6710QDSERQ1, TLV6700QDSERQ1 delivers identical accuracy and hysteresis at lower cost for 12-V systems; versus MAX9022AASA+, it eliminates external components and qualifies for automotive use - reducing design validation effort by 60%.

FAQ
What is the maximum input voltage allowed at INA+ and INB– pins of TLV6700QDSERQ1?
The absolute maximum input voltage at INA+ and INB– is 7 V, independent of VDD level. This allows safe monitoring of voltages up to 7 V directly, or higher voltages via external resistor dividers - ensuring compatibility with 5-V logic domains and protecting internal ESD structures per AEC-Q100 stress limits.
Does TLV6700QDSERQ1 require external hysteresis components?
No, TLV6700QDSERQ1 includes built-in 5.5 mV typical hysteresis on both comparators. This eliminates external resistors and ensures consistent noise immunity across temperature and supply variations - critical for rejecting transients during load dump or cold-crank events in automotive environments.
Can TLV6700QDSERQ1 outputs drive a 12-V logic input directly?
Yes, TLV6700QDSERQ1 open-drain outputs are rated to 18 V and can be pulled up to 12 V - enabling direct interface to 12-V automotive microcontrollers or CAN transceivers without level-shifting circuitry. The device maintains 300 nA max leakage at 18 V, ensuring clean high-state logic levels.
What is the start-up delay specification for TLV6700QDSERQ1?
TLV6700QDSERQ1 has a maximum start-up delay of 450 µs after VDD exceeds 1.8 V. During this period, outputs remain in a known state per Table 8-1 - allowing system designers to implement reliable power-on sequencing and avoid spurious fault assertions during power ramp-up in automotive ECUs.
How does TLV6700QDSERQ1 handle undervoltage lockout conditions?
When VDD falls below 1.3–1.7 V (UVLO threshold), TLV6700QDSERQ1 drives OUTA low and places OUTB in high-impedance state - providing a deterministic fault signal for system reset controllers. Below 0.8 V (power-on reset voltage), both outputs enter high-impedance mode to prevent undefined behavior during deep brownout.
