Product details
Overview
LT6700MPDCB-3#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, two noninverting inputs, open-collector outputs, 6.5µA supply current at 5V, and –55°C to 125°C operating range. It functions as a precision threshold detector in battery monitoring and industrial control systems where low quiescent power and wide temperature tolerance are critical.
For engineers reviewing the LT6700MPDCB-3#TRMPBF datasheet, LT6700MPDCB-3#TRMPBF pinout, LT6700MPDCB-3#TRMPBF application, or LT6700MPDCB-3#TRMPBF equivalent, this page delivers verified electrical specifications, package mapping, input polarity confirmation (dual noninverting), hysteresis behavior (6.5mV typ), and automotive-grade thermal performance for direct design-in evaluation.
Technical Context
The LT6700MPDCB-3#TRMPBF implements two independent comparators, each with one externally accessible noninverting input (+INA, +INB) and the second input internally tied to the 400mV reference. Its Over-The-Top® input architecture allows input voltages up to 36V regardless of supply voltage (1.4V–18V), enabling direct high-side sensing without level-shifting.
Both open-collector outputs (OUTA, OUTB) support sinking ≥5mA and tolerate off-state voltages up to 36V, permitting level translation across disparate supply domains. Internal hysteresis (6.5mV typ) eliminates external feedback components and ensures stable switching under noisy conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 18V - Enables operation from single-cell Li-ion (2.7V) up to industrial 12V/15V rails without external regulators. |
| Quiescent Current | 6.5µA typ at 5V - Supports >1-year battery life in always-on monitoring applications with alkaline AA cells. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - Ensures precise 400mV trip point without calibration for voltage supervision. |
| Hysteresis | 6.5mV typ - Prevents chatter on slow-rising/falling signals; eliminates need for external hysteresis resistors. |
| Input Voltage Range | –0.3V to 36V relative to GND - Allows direct connection to high-voltage nodes (e.g., 24V bus, battery packs) independent of VS. |
| Output Sink Current | ≥5mA guaranteed over temperature - Drives LEDs, MOSFET gates, or optocouplers directly without buffer stages. |
| Operating Temperature | –55°C to 125°C - Qualified for extended-temperature industrial, automotive under-hood, and aerospace environments. |
Pinout & Package
LT6700MPDCB-3#TRMPBF uses a 6-lead (2mm × 3mm) plastic DFN package with exposed pad (internally connected to GND). Pin 7 is soldered exposed pad for thermal enhancement and must be connected to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output of Comparator A | Sinks ≥5mA; off-state voltage up to 36V - interfaces directly with 3.3V/5V/12V logic or relay drivers. |
| GND | Ground reference and reference low-side terminal | Common return for internal 400mV reference and all circuitry; connects to exposed pad for thermal management. |
| +INA | Noninverting input of Comparator A | Accepts –0.3V to 36V; compares against internal 400mV reference - used for high-side voltage monitoring. |
| OUTB | Open-collector output of Comparator B | Independent sink path; enables dual-threshold detection (e.g., under/over-voltage) with shared reference. |
| VS | Core supply voltage | Powers comparator core only; does not limit input/output voltage ranges - decouples supply noise from signal path. |
| +INB | Noninverting input of Comparator B | Dual noninverting configuration (LT6700-3 variant) - supports parallel threshold detection or redundant monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Dual noninverting inputs (+INA, +INB) | Enables simultaneous high-side sensing of two independent voltages against the same 400mV reference - ideal for window monitoring without inversion logic. |
| Internal 400mV reference | Eliminates external reference ICs and trimming components; ±1.25% max error reduces BOM count and layout area in space-constrained designs. |
| Over-The-Top® input capability | Supports input voltages up to 36V while powered from 1.4V - removes level-shifters in battery pack voltage monitoring and 24V industrial I/O. |
| 6.5µA quiescent current | Extends battery life in portable instruments and remote sensors; enables continuous monitoring without duty cycling. |
| –55°C to 125°C operation | Validated for extreme environments including automotive engine compartments, outdoor telecom equipment, and military-grade systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator with reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6700IDCB-3#TRMPBF | Same pinout and function but rated for –40°C to 85°C industrial range; 13µA max supply current vs 13.0µA typ for LT6700MPDCB-3#TRMPBF. | Lacks extended low-temperature capability; unsuitable for cold-climate automotive or aerospace deployments. | Select when cost sensitivity outweighs extended temperature needs and ambient stays above –40°C. |
| TLV3702IDR | Single-supply dual comparator with 1.8V–16V range, no integrated reference; requires external 400mV source; 850nA quiescent current. | Higher accuracy possible with precision external reference, but adds BOM cost, layout area, and calibration complexity. | Choose only if ultra-low power (<1µA) dominates over integration and simplicity in battery-critical designs. |
Compared with LT6700IDCB-3#TRMPBF, the LT6700MPDCB-3#TRMPBF provides guaranteed operation down to –55°C and tighter supply current spec (6.5µA typ), while TLV3702IDR trades integration for lower quiescent current but demands external reference design and validation effort.
