Product details
Overview
LT6700HS6-2#TRPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for low-voltage system monitoring in harsh environments. It features two inverting inputs, open-collector outputs rated to 18V, 6.5µA typical supply current at 5V, ±10nA max input bias current, and operates across –40°C to 125°C.
For engineers reviewing the LT6700HS6-2#TRPBF datasheet, LT6700HS6-2#TRPBF pinout, LT6700HS6-2#TRPBF application, or LT6700HS6-2#TRPBF equivalent, this device supports precision threshold detection in battery-powered industrial sensors, automotive voltage monitors, and high-reliability power-supply supervisors where wide supply range (1.4V–18V) and internal hysteresis are critical.
Technical Context
The LT6700HS6-2#TRPBF implements two independent comparators, each with one externally accessible inverting input and the other tied internally to the 400mV reference. Its Over-The-Top® input architecture allows input voltages up to 18V regardless of supply voltage, enabling direct sensing of higher-voltage rails without level-shifting.
Both open-collector outputs sink ≥5mA over temperature and support level translation by referencing the load to any voltage ≤18V. Internal hysteresis (6.5mV typ) eliminates oscillation near thresholds, simplifying design for stable trip-point behavior 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 applications |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures precise 400mV trip point without external calibration |
| Hysteresis | 6.5mV typ - provides noise immunity without requiring external resistors |
| Input Bias Current | ±10nA max - minimizes loading on high-impedance sensor dividers |
| Output Sink Capability | >5mA over temperature - directly drives LEDs, small relays, or logic inputs without buffer stages |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
Package: 6-lead plastic TSOT-23 (S6), 1mm profile, RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND | Ground reference and reference low-side | Common return for internal 400mV reference and all circuitry; must be connected to system ground |
| –INA | Inverting input of Comparator A | Voltage applied here is compared against internal 400mV reference; polarity matches LT6700-2 variant |
| OUTB | Open-collector output of Comparator B | Independent output with same sinking capability and voltage rating as OUTA |

| –INB | Inverting input of Comparator B | Second inverting input; enables dual-threshold or redundant monitoring with matched reference |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400mV reference | Eliminates need for external precision reference or resistor divider, reducing BOM count and layout area |
| Over-The-Top® input operation | Allows –IN pins to accept signals up to 18V even when VS = 1.4V, enabling direct high-side sensing |
| Internal hysteresis | 6.5mV typical hysteresis reduces sensitivity to noise and prevents chatter without external components |
| AEC-Q100 qualified | Rated for automotive applications per Grade H (–40°C to 125°C), supporting functional safety-critical monitoring |
| Low input bias current | ±10nA max enables use with megaohm-level sensor dividers without significant offset error |
Applications
| Battery Voltage Monitor | Power Supply Supervisor |
|---|---|
Use Scenario: Monitoring lithium-ion cell voltage during discharge to trigger low-battery warning before cutoff. IC Role / Device Role / Timing Role: Dual comparator compares cell voltage against 400mV reference scaled via resistor divider to detect 3.0V and 2.8V thresholds. Use Value: Micropower operation extends battery life; internal hysteresis prevents false triggers during transient load dips. | Use Scenario: Validating 5V and 3.3V rail integrity in industrial PLC I/O modules during startup and runtime. IC Role / Device Role / Timing Role: Each comparator independently supervises one rail using dedicated inverting inputs and shared 400mV reference. Use Value: Single IC replaces two discrete comparators + reference, reducing footprint and improving matching between thresholds. |
| Automotive Cabin Sensor | Industrial Temperature Transmitter |
Use Scenario: Detecting overtemperature condition in HVAC blower motor control using NTC thermistor divider. IC Role / Device Role / Timing Role: Comparator A monitors high-temp trip; Comparator B monitors fault condition (open/short) via second threshold. Use Value: –40°C to 125°C rating ensures reliability under hood; Over-The-Top® input accommodates 12V sensor supply while VS runs from 3.3V LDO. | Use Scenario: Providing fail-safe 4–20mA loop supervision in hazardous-area temperature transmitters. IC Role / Device Role / Timing Role: One comparator validates loop current presence; the other detects overcurrent or open-wire fault using reference-based thresholds. Use Value: Open-collector outputs interface directly with 24V loop supply; 6.5µA quiescent current meets intrinsic safety power budgets. |
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 |
|---|---|---|---|
| LT6700IS6-2#TRPBF | Same functionality but rated for –40°C to 85°C industrial range; lower max operating temperature | Suitable for non-automotive industrial controls where extended temperature is not required | Select when cost sensitivity outweighs need for 125°C operation and AEC-Q100 qualification |
| TLV3702IDR | Single-supply dual comparator with 1.24V reference; no internal hysteresis; 850nA supply current | Requires external hysteresis resistors and reference scaling; higher power consumption | Choose only if 1.24V reference aligns with existing design and board space permits external components |
Compared with LT6700IS6-2#TRPBF, the LT6700HS6-2#TRPBF adds automotive-grade temperature range and AEC-Q100 qualification; versus TLV3702IDR, it integrates hysteresis and a lower 400mV reference, reducing component count and enabling ultra-low-power operation.

FAQ
What is the function of the –INA and –INB pins on the LT6700HS6-2#TRPBF?
The –INA and –INB pins are the externally accessible inverting inputs for Comparator A and Comparator B, respectively. Each is compared against the internal 400mV reference. For the LT6700HS6-2#TRPBF, both inputs are inverting - meaning the corresponding output goes low when the input voltage falls below the reference. This configuration supports dual-threshold detection or redundancy in critical monitoring circuits.
Does the LT6700HS6-2#TRPBF require external hysteresis components?
No, the LT6700HS6-2#TRPBF includes internal hysteresis of 6.5mV typical, eliminating the need for external feedback resistors. This built-in hysteresis stabilizes output transitions near the 400mV threshold and is inherent to the LT6700HS6-2#TRPBF's comparator design, simplifying PCB layout and improving consistency across temperature and unit-to-unit variation.
Can the LT6700HS6-2#TRPBF operate with a 1.4V supply and still interface with a 12V load?
Yes. The LT6700HS6-2#TRPBF's open-collector outputs support off-state voltages up to 18V, independent of the 1.4V to 18V supply (VS). When VS = 1.4V, OUTA and OUTB can still switch a 12V pull-up load - enabling level translation without additional circuitry. This Over-The-Top® capability is a core feature of the LT6700HS6-2#TRPBF.
What is the maximum input voltage allowed at –INA or –INB for the LT6700HS6-2#TRPBF?
The absolute maximum input voltage at –INA or –INB is 18.5V above GND (or 40V for HV variants, but LT6700HS6-2#TRPBF is standard-voltage). Per the datasheet, inputs operate safely from (GND – 0.3V) to 18.5V regardless of VS. This allows direct connection to 12V or 15V rails while powering the LT6700HS6-2#TRPBF from a low-voltage LDO - a key advantage in mixed-rail systems.
Is the LT6700HS6-2#TRPBF pin-compatible with other LT6700 variants in the SOT-23 package?
Yes - all LT6700xS6 variants (e.g., LT6700HS6-1, LT6700HS6-3, LT6700IS6-2) share identical 6-lead TSOT-23 pinouts. Pin functions (OUTA, GND, –INA, OUTB, VS, –INB) are fixed per variant type; only the input polarity differs between -1/-2/-3 versions. Thus, the LT6700HS6-2#TRPBF is mechanically and electrically pin-compatible with other S6-packaged LT6700 parts, allowing drop-in replacement where input polarity matches the design.
