Product details
Overview
TLV6700DDCT from Texas Instruments is a micropower, 18-V window comparator IC with integrated 400-mV reference, dual open-drain outputs rated to 18 V, ±0.5% threshold accuracy at 25°C, and 5.5 µA typical quiescent current. It operates as a voltage window detector for overvoltage/undervoltage monitoring in battery-powered systems using external resistor dividers.
For engineers reviewing the TLV6700DDCT datasheet, TLV6700DDCT pinout, TLV6700DDCT application, or TLV6700DDCT equivalent, key selection criteria include its 1.8–18 V supply range, 400-mV internal reference with 1.0% max overtemperature accuracy, built-in 5.5 mV hysteresis, –40°C to 125°C operation, and SOT-23-6 (DDC) package compatibility with space-constrained portable designs.
Technical Context
The TLV6700DDCT integrates two independent high-accuracy comparators sharing a single 400-mV internal reference: INA+ drives OUTA low when input falls below (VIT+ – VHYS), while INB– drives OUTB low when input rises above VIT+. Both outputs feature open-drain topology with 18-V absolute maximum rating independent of VDD.
Its architecture supports flexible configuration - either as a window comparator (using both inputs) or as two discrete voltage monitors. Input terminals accept 0–6.5 V signals regardless of supply voltage, and built-in hysteresis rejects noise-induced false triggering without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 18 V - enables direct monitoring of 3.3 V, 5 V, 12 V, and 15 V rails without level-shifting. |
| Reference Voltage | 400 mV ±0.5% (25°C), ±1.0% (–40°C to 125°C) - provides stable, temperature-compensated threshold baseline for precision window detection. |
| Quiescent Current | 5.5 µA (typ) - supports multi-year battery life in always-on sensing applications like door/window sensors and portable medical devices. |
| Hysteresis Voltage | 5.5 mV (typ), up to 12 mV (max) - suppresses chatter on noisy supply lines without requiring external RC networks. |
| Input Threshold Accuracy | ±0.5% at 25°C, ±1.0% over full temperature range - ensures reliable trip points across automotive and industrial ambient conditions. |
| Output Type | Open-drain, 18-V rated - allows pull-up to any voltage ≤18 V, enabling interface with higher-voltage logic or wired-OR fault signaling. |
| Propagation Delay | tPHL = 18 µs, tPLH = 29 µs (VDD = 5 V, 10-mV overdrive) - balances speed and power for real-time rail monitoring without excessive bandwidth. |
Pinout & Package
TLV6700DDCT is packaged in a Thin SOT-23-6 (DDC) case measuring 2.90 mm × 1.60 mm, optimized for compact PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | INA+ comparator output | Open-drain output asserted low when INA+ drops below (VIT+ – VHYS); high-impedance otherwise - used for undervoltage flag generation. |
| GND | Ground reference | Analog and digital ground return path; must be low-impedance and decoupled with 0.1-µF ceramic capacitor near VDD. |
| INA+ | Noninverting input | Monitors rising/falling voltage via external resistor divider; low 25 nA input leakage preserves accuracy with high-value dividers. |
| OUTB | INB– comparator output | Open-drain output asserted low when INB– exceeds VIT+; high-impedance otherwise - used for overvoltage flag generation. |
| VDD | Power supply input | Accepts 1.8–18 V; powers internal reference and comparators; requires local 0.1-µF bypass capacitor. |
| INB– | Inverting input | Monitors voltage via external resistor divider; polarity enables overvoltage detection when signal exceeds VIT+ threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable window thresholds | Set via external resistor dividers - supports monitoring of any rail ≥400 mV (e.g., 12 V ±10%, 5 V ±5%) without trimming. |
| Internal 400-mV reference | 0.5% accuracy at 25°C, 1.0% over –40°C to 125°C - eliminates need for external precision reference, reducing BOM count and layout area. |
| 18-V open-drain outputs | Rated to 18 V regardless of VDD - enables direct interfacing with 3.3 V, 5 V, or 12 V microcontrollers and fault-bus signaling. |
| Micropower operation | 5.5 µA typical IDD - extends battery life in always-active applications such as IoT sensors and wearable health monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar window comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6710DSE | Wider 1.8–36 V supply range; 0.75% max threshold accuracy over temperature; WSON-6 package only. | Supports 24 V industrial systems and higher-voltage battery stacks where TLV6700DDCT's 18 V limit is insufficient. | Choose TLV6710DSE when monitoring >18 V rails or requiring tighter 0.75% threshold tolerance; not pin-compatible with TLV6700DDCT due to different package and pinout. |
| TLV6703DDCR | Single-channel non-inverting comparator; same 1.8–18 V range, 400-mV reference, and 5.5 µA IQ; SOT-23-5 package. | Used for dedicated overvoltage or undervoltage detection only - lacks second input for true window functionality. | Choose TLV6703DDCR when only one threshold is needed and board space permits separate UV/OV ICs; requires two units to replicate TLV6700DDCT's dual-channel behavior. |
Compared with TLV6710DSE and TLV6703DDCR, the TLV6700DDCT uniquely delivers dual-window detection in a single SOT-23-6 footprint with guaranteed 1.0% threshold accuracy and 18-V output capability - making it optimal for cost- and space-sensitive 12 V portable systems.

FAQ
What is the function of the INB– pin on the TLV6700DDCT?
The INB– pin on the TLV6700DDCT serves as the inverting input for the second comparator, enabling overvoltage detection. When the voltage at INB– exceeds the internal 400-mV reference (VIT+), the TLV6700DDCT drives OUTB low. This polarity allows the TLV6700DDCT to form a complete window comparator when paired with INA+, supporting precise upper-threshold monitoring without external inversion circuitry.
Can the TLV6700DDCT monitor a 24-V rail?
No, the TLV6700DDCT cannot directly monitor a 24-V rail because its absolute maximum input voltage on INA+ and INB– is 6.5 V, and its VDD supply is limited to 18 V. However, a properly scaled external resistor divider can reduce the 24-V signal to within the 0–6.5 V input range while preserving threshold accuracy - but the TLV6700DDCT itself remains unsuitable for direct 24-V connection.
Does the TLV6700DDCT require external hysteresis components?
No, the TLV6700DDCT includes built-in hysteresis of 5.5 mV (typical), which is factory-trimmed and temperature-stable. This eliminates the need for external positive feedback resistors or RC networks, simplifying PCB layout and ensuring consistent noise immunity across –40°C to 125°C without design iteration.
What is the maximum sink current capability of TLV6700DDCT outputs?
The TLV6700DDCT outputs are rated for 40 mA maximum sink current per channel (OUTA or OUTB), as specified in Absolute Maximum Ratings. In normal operation, typical VOL is 250 mV at 5 mA sink (VDD = 5 V), confirming robust drive strength for direct GPIO interfacing or driving small LEDs and optocouplers without external buffers.
Is the TLV6700DDCT pin-compatible with other members of the TLV67xx family?
No, the TLV6700DDCT is not pin-compatible with other TLV67xx variants. For example, TLV6703DDCR uses SOT-23-5 (5-pin), TLV6710DSE uses WSON-6 with different pin mapping, and TLV6700DDCT's SOT-23-6 (DDC) pinout is unique to this part. Board redesign is required when substituting across the family due to differing pin counts, functions, and package footprints.
