Product details
Overview
LT6700HDCB-1#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for high-temperature system monitoring. It features one inverting and one noninverting input (–INA, +INB), open-collector outputs rated to 18V, 6.5µA supply current at 5V, ±10nA max input bias current, and operates from 1.4V to 18V supply across –40°C to 125°C.
For engineers reviewing the LT6700HDCB-1#TRMPBF datasheet, LT6700HDCB-1#TRMPBF pinout, LT6700HDCB-1#TRMPBF application, or LT6700HDCB-1#TRMPBF equivalent, this part supports precision low-voltage threshold detection, window-comparator configurations, and industrial battery monitoring where wide supply range, internal hysteresis (6.5mV typ), and over-the-top input capability are critical.
Technical Context
The LT6700HDCB-1#TRMPBF integrates two independent comparators sharing a precision 400mV internal reference; each has one externally accessible input while the other connects internally to the reference. Its input stage supports Over-The-Top® operation down to ground and up to 18V regardless of VS, enabling direct sensing of signals beyond the supply rail.
Both open-collector outputs sink ≥5mA and tolerate off-state voltages up to 18V, allowing level translation and interface with higher-voltage logic or relay drivers. Internal hysteresis (6.5mV typical) eliminates external components for stable switching in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.4V to 18V - enables operation from single-cell Li-ion or alkaline up to industrial 12V/15V rails |
| Quiescent Current | 6.5µA typ at 5V - supports multi-year battery life in always-on monitoring systems |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures reliable trip-point repeatability without calibration |
| Hysteresis | 6.5mV typ - suppresses chatter on slow or noisy input edges without external RC networks |
| Input Bias Current | ±10nA max - minimizes voltage drop across high-impedance sensor dividers (e.g., thermistors) |
| Output Sink Capability | >5mA guaranteed over temperature - directly drives LEDs, small relays, or MOSFET gates |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
LT6700HDCB-1#TRMPBF uses a 6-lead (2mm × 3mm) plastic DFN package with exposed pad (internally connected to GND). Pin 7 is soldered exposed thermal pad; PCB connection is optional but recommended for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Open-collector output of Comparator A | Sinks ≥5mA; off-state voltage up to 18V - interfaces with 3.3V/5V/12V logic or discrete loads |
| GND (Pin 2) | Ground reference and reference low-side | Common return for supply, reference, and outputs; exposed pad (Pin 7) tied internally |
| –INA (Pin 3) | Inverting input of Comparator A | Accepts –0.3V to 18V regardless of VS - enables over-the-top sensing of battery or bus voltage |
| OUTB (Pin 4) | Open-collector output of Comparator B | Independent sinking output; used with OUTA for window-comparator or dual-threshold logic |
| VS (Pin 5) | Core supply voltage | Powers comparator core and reference; decoupling capacitor required near this pin |
| +INB (Pin 6) | Noninverting input of Comparator B | Configures LT6700-1 variant for window-comparator topology with –INA and +INB as outer thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400mV reference | Eliminates external reference IC or resistor divider, reducing BOM count and layout area |
| Over-The-Top® inputs | Allows direct sensing of signals below GND or above VS - e.g., battery voltage monitoring without level-shifting |
| Internal hysteresis | 6.5mV typical - removes need for external positive feedback resistors in noise-prone applications |
| Wide supply range (1.4V–18V) | Supports single-cell to multi-cell battery systems and industrial 12V/15V rails without LDO pre-regulation |
| AEC-Q100 qualified | Validated for automotive-grade reliability - suitable for engine control, ADAS power monitoring, and body electronics |

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-1#TRMPBF | Same pinout and function, but rated for –40°C to 85°C only; lower max junction temperature (125°C vs 150°C) | Suitable for commercial/industrial indoor applications, not under-hood automotive or extended-temperature industrial use | Select when ambient temperature stays below 85°C and cost sensitivity outweighs extended temp requirement |
| TLV3701IDBVR | Single comparator with 1.24V reference; no internal hysteresis; 650nA quiescent current; SOT-23-6 package | Lacks dual-channel integration and fixed 400mV reference; requires external hysteresis and scaling for window detection | Choose only for ultra-low-power single-threshold detection where dual functionality and reference accuracy are not required |
Compared with LT6700IDCB-1#TRMPBF, the LT6700HDCB-1#TRMPBF delivers guaranteed operation to 125°C and higher reliability for automotive under-hood use; versus TLV3701IDBVR, it provides integrated dual channels, precise 400mV reference, and built-in hysteresis-reducing component count and design complexity for window-monitoring tasks.

FAQ
What is the operating temperature range of the LT6700HDCB-1#TRMPBF?
The LT6700HDCB-1#TRMPBF is specified for operation from –40°C to 125°C and is qualified per AEC-Q100 Grade 1, making it suitable for under-hood automotive and high-temperature industrial environments. This range is confirmed in the Absolute Maximum Ratings table and applies across all electrical specifications unless otherwise noted.
Does the LT6700HDCB-1#TRMPBF require external hysteresis components?
No, the LT6700HDCB-1#TRMPBF includes internal hysteresis of 6.5mV typical, eliminating the need for external positive feedback resistors. This simplifies design for stable threshold detection in noisy environments and is inherent to the comparator architecture - no configuration or external parts are needed to activate it.
Can the LT6700HDCB-1#TRMPBF monitor voltages higher than its supply voltage (VS)?
Yes, the LT6700HDCB-1#TRMPBF supports Over-The-Top® inputs: both –INA and +INB accept voltages from –0.3V to 18V relative to GND, independent of VS. This allows direct monitoring of battery or bus voltages exceeding the core supply - for example, sensing a 12V rail while powered from 3.3V.
What is the reference voltage accuracy of the LT6700HDCB-1#TRMPBF?
The LT6700HDCB-1#TRMPBF features a precision internal 400mV reference with total threshold error of ±1.25% maximum at 25°C. This includes contributions from reference tolerance, comparator offset, and temperature drift - verified across the full –40°C to 125°C range per the Electrical Characteristics tables.
Is the LT6700HDCB-1#TRMPBF pin-compatible with other LT6700 variants in the DFN package?
Yes, all LT6700x-1 variants in the DCB6 (2mm × 3mm DFN) package - including LT6700CDCB-1#TRMPBF, LT6700IDCB-1#TRMPBF, and LT6700HDCB-1#TRMPBF - share identical pinout, footprint, and terminal functions. Only the temperature grade and test screening differ; no PCB redesign is needed when upgrading from commercial to high-temp versions.
