Product details
Overview
TLV6700QDDCRQ1 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 TLV6700QDDCRQ1 datasheet, TLV6700QDDCRQ1 pinout, TLV6700QDDCRQ1 application, or TLV6700QDDCRQ1 equivalent, this page delivers verified functional role, validated pin functions for SOT-23-6 (DDC), confirmed threshold hysteresis (5.5 mV typ), automotive-grade ESD ratings (HBM H2, CDM C6), and real-world window-comparator use cases in eCall and OBC systems.
Technical Context
The TLV6700QDDCRQ1 integrates two independent comparators sharing a precision 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 regardless of VDD, enabling direct interface with higher-voltage logic or wired-OR fault signaling.
It operates across –40°C to 125°C junction temperature with built-in 5.5 mV typical hysteresis, 1.0% max threshold accuracy over temperature, and undervoltage lockout (UVLO) at 1.3–1.7 V - ensuring robust startup and noise immunity in automotive 12-V and 48-V subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.8 V to 18 V - supports direct connection to automotive battery rails including cold-crank (≥1.8 V) and load-dump transients (≤18 V). |
| Reference voltage | 400 mV ±0.5% (25°C), ±1.0% (–40°C to 125°C) - enables precise window thresholds via external resistor dividers without external reference. |
| Quiescent current | 5.5 µA (typ) at 1.8 V - allows always-on monitoring in low-power automotive modules like eCall backup circuits. |
| Hysteresis | 5.5 mV (typ), ≤12 mV (max) - rejects short-duration noise spikes and prevents output chatter during slow-rising/falling monitored voltages. |
| Output type | Open-drain, 18-V tolerant - permits pull-up to any rail up to 18 V independent of VDD, enabling mixed-voltage system interfacing. |
| Input leakage | ±25 nA (INA+), ±15 nA (INB–) - allows use of high-value resistor dividers (>1 MΩ) without significant threshold error. |
| Propagation delay | 18 µs (tPHL), 29 µs (tPLH) at 5 V - ensures timely fault detection while avoiding false triggers from fast transients. |
Pinout & Package
TLV6700QDDCRQ1 is packaged in thin SOT-23-6 (DDC) with 2.90 mm × 1.60 mm body size. Pinout is validated per TI SNVSBG5 datasheet Figure 6-1 and Table 6-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUTB | Comparator B open-drain output | Drives low when INB– exceeds VIT+; high-impedance otherwise - used for overvoltage flag in window configuration. |
| 2: VDD | Positive supply input | Accepts 1.8–18 V; requires local 0.1-µF ceramic decoupling capacitor for stable operation under load transients. |
| 3: INB– | Inverting input for comparator B | Monitors rising voltage (e.g., battery overvoltage); threshold set by external resistor divider to 400 mV reference. |
| 4: OUTA | Comparator A open-drain output | Drives low when INA+ falls below (VIT+ – VHYS) - used for undervoltage flag in window configuration. |
| 5: GND | Analog ground reference | Return path for internal reference and comparator inputs; must be low-impedance connection to system ground plane. |
| 6: INA+ | Non-inverting input for comparator A | Monitors falling voltage (e.g., battery undervoltage); threshold set by external resistor divider to 400 mV reference. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the function of the TLV6700QDDCRQ1 in a window comparator circuit?
The TLV6700QDDCRQ1 implements a precision window comparator using its two independent comparators: INA+ detects undervoltage (driving OUTA low when input drops below VIT+ – VHYS), and INB– detects overvoltage (driving OUTB low when input exceeds VIT+). Its internal 400-mV reference and 5.5 mV hysteresis eliminate external components, and the TLV6700QDDCRQ1 maintains ±1.0% threshold accuracy from –40°C to 125°C for reliable automotive operation.
Does the TLV6700QDDCRQ1 require an external reference voltage?
No, the TLV6700QDDCRQ1 does not require an external reference voltage. It integrates a factory-trimmed 400-mV internal reference with ±0.5% accuracy at 25°C and ±1.0% over temperature (–40°C to 125°C). This reference is shared by both comparators and enables precise window thresholds using only external resistor dividers - simplifying design and reducing BOM count compared to discrete comparator solutions.
What are the absolute maximum ratings for the TLV6700QDDCRQ1 inputs and outputs?
The TLV6700QDDCRQ1 has absolute maximum ratings of –0.3 V to 20 V on VDD and OUTA/OUTB pins, and –0.3 V to 7 V on INA+/INB– inputs. Output terminals can sink up to 40 mA. Exceeding these limits may cause permanent damage. The device operates safely within recommended conditions: VDD = 1.8–18 V, INA+/INB– = 0–6.5 V, and OUTA/OUTB = 0–18 V - all fully validated for automotive Grade 1 environments.
Can the TLV6700QDDCRQ1 outputs interface with logic running at voltages higher than its VDD?
Yes, the TLV6700QDDCRQ1 open-drain outputs (OUTA and OUTB) are rated to 18 V regardless of VDD level, allowing pull-up to any voltage rail up to 18 V - including 5-V, 12-V, or 18-V microcontroller GPIOs. This enables mixed-voltage system interfacing without level shifters. The TLV6700QDDCRQ1's 18-V tolerance is specified in Section 7.1 Absolute Maximum Ratings and confirmed in the Functional Block Diagram.
How does the TLV6700QDDCRQ1 handle undervoltage conditions on its supply rail?
The TLV6700QDDCRQ1 incorporates undervoltage lockout (UVLO) with activation between 1.3 V and 1.7 V. When VDD falls within the UVLO range (above power-on reset VPOR = 0.8 V but below UVLO), OUTA is driven low and OUTB goes high-impedance - providing a defined fault state. Below VPOR, both outputs enter high-impedance. This behavior ensures predictable operation during brownout and cold-crank events, and is fully characterized in Section 7.5 Electrical Characteristics of the TLV6700QDDCRQ1 datasheet.
