Product details
Overview
LT6700IS6-3#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for low-voltage system monitoring in industrial and automotive applications. It features two noninverting inputs, open-collector outputs rated to 18V, 6.5µA typical supply current at 5V, ±10nA max input bias current, and internal 6.5mV typical hysteresis - enabling robust threshold detection in battery-powered sensors and power-rail monitors.
For engineers reviewing the LT6700IS6-3#TRMPBF datasheet, LT6700IS6-3#TRMPBF pinout, LT6700IS6-3#TRMPBF application, or LT6700IS6-3#TRMPBF equivalent, this part supports precise 400mV-referenced voltage monitoring across 1.4V–18V supplies, operates from –40°C to 85°C, and delivers stable open-collector output sinking >5mA with level-translating capability independent of VS.
Technical Context
The LT6700IS6-3#TRMPBF implements two independent comparators, each with one externally accessible noninverting input (+INA, +INB) and the other internally tied to a precision 400mV reference. Its Over-The-Top® input architecture allows input voltages up to 18V (beyond VS), supporting high-side sensing without level-shifting circuitry.
Both open-collector outputs (OUTA, OUTB) are independently configurable for pull-up to any voltage ≤18V, decoupling output logic levels from the core supply. Internal hysteresis eliminates external feedback components and ensures noise-immune switching at the 400mV threshold, with total threshold error limited to ±1.25% at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.4V to 18V - enables operation directly from single-cell Li-ion, alkaline, or regulated rails without LDO pre-regulation. |
| Quiescent Current | 6.5µA typ at 5V - supports multi-year battery life in always-on monitoring circuits. |
| Reference Voltage | 400mV ±1.25% max at 25°C - provides stable, temperature-compensated threshold for low-voltage brownout or charge-level detection. |
| Input Bias Current | ±10nA max - minimizes voltage drop across high-impedance divider networks (e.g., 1MΩ+). |
| Hysteresis | 6.5mV typ - suppresses chatter on noisy signals without requiring external resistor networks. |
| Output Sink Current | >5mA over temperature - drives LEDs, MOSFET gates, or relay coils directly without buffer stages. |
| Operating Temp | –40°C to +85°C - qualified for industrial control and under-hood automotive subsystems. |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 1mm profile, RoHS-compliant, lead-free finish. Exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Open-collector output A | Sinks current when comparator A trips; pull-up voltage may be up to 18V, independent of VS. |
| 2 - GND | Ground reference | Common return for internal 400mV reference and comparator core; must be connected to system ground. |
| 3 - +INA | Noninverting input A | Accepts input from –0.3V to 18V vs GND; compares against internal 400mV reference. |
| 4 - –INB | Inverting input B | Not applicable for LT6700IS6-3 - this is the LT6700-3 variant, so Pin 4 is +INB (noninverting). Correction: Pin 4 = +INB. |
| 5 - VS | Core supply voltage | Powers comparator core and reference; range 1.4V–18V; no reverse-polarity protection. |
| 6 - OUTB | Open-collector output B | Independent of OUTA; enables dual-threshold or window-monitoring configurations with shared reference. |
Key Features
| Feature | Design Value |
|---|---|
| Dual noninverting inputs (+INA, +INB) | Enables simultaneous monitoring of two rising-edge thresholds (e.g., battery OK and battery full) using same 400mV reference. |
| Over-The-Top® input capability | Accepts inputs up to 18V regardless of VS - supports direct connection to unregulated 12V/24V rails without attenuation or clamping. |
| Internal 400mV reference | Eliminates external reference IC or resistor divider; reduces BOM count and layout area while maintaining ±1.25% accuracy. |
| Guaranteed >5mA sink per output | Drives standard indicator LEDs or small-signal N-channel MOSFETs directly - avoids need for discrete transistor buffers. |
| 6.5µA quiescent current | Enables continuous monitoring in energy-constrained IoT nodes and portable medical devices with multi-year battery life. |
Applications

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 |
|---|---|---|---|
| LT6700IS6-1#TRMPBF | One inverting (+INA) and one inverting (–INB) input - configured as window comparator with common reference. | Used where both high- and low-threshold detection required (e.g., voltage in-range flag), unlike LT6700IS6-3's dual rising-edge detection. | Select LT6700IS6-1 when implementing window-based pass/fail logic; LT6700IS6-3 is optimal for dual upper-threshold monitoring. |
| TLV3603IDBVR | No integrated reference; requires external 400mV source or resistor divider; higher 15µA supply current; only one comparator per package. | Requires additional components for reference generation and hysteresis; less suitable for space-constrained dual-threshold designs. | Choose TLV3603IDBVR only if higher speed (<100ns propagation delay) is critical and board area permits external reference circuitry. |
Compared with LT6700IS6-1#TRMPBF and TLV3603IDBVR, the LT6700IS6-3#TRMPBF uniquely combines dual noninverting inputs, integrated 400mV reference, sub-7µA quiescent current, and industrial temperature range in a 6-pin SOT-23 - delivering lowest component count and power for dual rising-threshold monitoring.

FAQ
What is the reference voltage accuracy of the LT6700IS6-3#TRMPBF over temperature?
The LT6700IS6-3#TRMPBF features a 400mV internal reference with total threshold error of ±1.25% maximum at 25°C. Over the full –40°C to +85°C operating range, typical drift is <±3mV, verified by production testing and characterized in the datasheet's temperature plots (Figure G04–G05). This ensures reliable low-voltage detection without external calibration.
Can the LT6700IS6-3#TRMPBF operate with a 1.4V supply and still drive a 5V logic input?
Yes. The LT6700IS6-3#TRMPBF open-collector outputs (OUTA, OUTB) are fully level-translating: they can be pulled up to any voltage ≤18V, independent of the 1.4V core supply (VS). When VS = 1.4V, OUTA/OUTB remain functional and can interface directly with 5V CMOS inputs using a 5V pull-up resistor - no level shifter required.
What is the maximum input voltage allowed on +INA or +INB pins of the LT6700IS6-3#TRMPBF?
The LT6700IS6-3#TRMPBF supports Over-The-Top® inputs: +INA and +INB accept voltages from –0.3V to 18V relative to GND, regardless of VS value. This allows direct monitoring of 12V automotive rails or 15V industrial supplies even when VS is powered from a lower 3.3V rail - eliminating external attenuators or clamps.
Does the LT6700IS6-3#TRMPBF require external hysteresis components?
No. The LT6700IS6-3#TRMPBF integrates 6.5mV typical hysteresis per comparator, implemented internally to prevent oscillation near the 400mV threshold. This eliminates the need for external positive-feedback resistors, simplifying design, saving PCB area, and ensuring consistent hysteresis performance across temperature and process variation.
Is the LT6700IS6-3#TRMPBF pin-compatible with other LT6700 variants in the SOT-23 package?
Yes - all LT6700xS6 variants (e.g., LT6700IS6-1, LT6700IS6-2, LT6700IS6-3) share identical 6-pin TSOT-23 pinout and footprint. Only the input polarity differs: LT6700IS6-3 has +INA and +INB, while LT6700IS6-1 has +INA and –INB. No PCB redesign is needed when selecting between variants for different threshold configurations.
