Product details
Overview
LT6700HVIS6-2#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 inverting inputs, 6.5µA typical supply current at 5V, ±10nA max input bias current, and open-collector outputs rated to 36V-enabling level translation independent of supply voltage.
For engineers reviewing the LT6700HVIS6-2#TRMPBF datasheet, LT6700HVIS6-2#TRMPBF pinout, LT6700HVIS6-2#TRMPBF application, or LT6700HVIS6-2#TRMPBF equivalent, this device is selected for battery voltage supervision, threshold detection with hysteresis, and relay driving where wide supply range (1.4V–18V), rail-to-rail input capability, and AEC-Q100-compliant temperature operation (–40°C to 85°C) are critical.
Technical Context
The LT6700HVIS6-2#TRMPBF integrates two independent comparators, each with one externally accessible inverting input and the other internally tied to a precision 400mV reference. Its Over-The-Top® input architecture allows input voltages up to 36V regardless of VS, supporting direct high-side sensing in battery and power rail monitoring.
Hysteresis is built-in (6.5mV typ), eliminating external feedback components. The open-collector outputs sink ≥5mA and tolerate up to 36V off-state voltage, enabling flexible pull-up configurations across diverse logic families and voltage domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.4V to 18V - supports single-cell Li-ion, alkaline, and 12V automotive systems without LDO pre-regulation. |
| Quiescent Current | 6.5µA typ at 5V - enables multi-year battery life in always-on monitoring circuits. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures precise trip points without calibration. |
| Input Voltage Range | –0.3V to 36V relative to GND - permits direct connection to battery terminals or unregulated rails. |
| Hysteresis | 6.5mV typ - prevents output oscillation near threshold without external resistor networks. |
| Output Sink Current | >5mA guaranteed over temperature - drives LEDs, small relays, or logic gates directly. |
| Operating Temp | –40°C to +85°C - qualified for industrial control and under-hood automotive environments. |
Pinout & Package
LT6700HVIS6-2#TRMPBF is housed in a 6-lead TSOT-23 (S6) package, 2.9mm × 1.6mm × 1.0mm profile, with exposed pad not connected internally (optional PCB thermal connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output of Comparator A | Sinks load current; off-state voltage up to 36V - enables level-shifting to higher-voltage logic or relay coils. |
| GND | Ground reference and reference low terminal | Common return for internal 400mV reference and all circuitry; must be low-impedance for accuracy. |
| –INA | Inverting input of Comparator A | Accepts signals from –0.3V to 36V; compares against internal 400mV reference - used for high-side threshold detection. |
| OUTB | Open-collector output of Comparator B | Independent output with same 36V tolerance and ≥5mA sink capability as OUTA. |
| VS | Core supply voltage | Powers comparator core and reference; operates down to 1.4V - supports energy harvesting and ultra-low-power designs. |
| –INB | Inverting input of Comparator B | Identical electrical behavior to –INA; enables dual-threshold or window detection with shared reference. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400mV reference | Eliminates external reference IC or resistor divider, reducing BOM count and layout area in space-constrained designs. |
| Two inverting inputs (–INA, –INB) | Enables direct high-side monitoring of positive rails (e.g., battery voltage > reference) without signal inversion circuitry. |
| Over-The-Top® input capability | Allows input voltages exceeding VS by up to 18V - simplifies sensing in buck converter feedback or battery pack monitoring. |
| Built-in 6.5mV hysteresis | Removes need for external positive feedback resistors, improving noise immunity and design repeatability across production lots. |
| AEC-Q100 qualified (Grade I) | Validated for automotive applications including body electronics and powertrain subsystems requiring robustness to temperature cycling and ESD. |

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#TRMPBF | Same pinout and function but non-HV version; input/output max 18V instead of 36V. | Restricted to ≤18V systems (e.g., 5V/12V embedded controllers); unsuitable for direct battery sensing in 24V automotive or industrial rails. | Select when supply and input voltages remain ≤18V and cost sensitivity outweighs HV margin. |
| TLV3702IDR | Single-supply dual comparator with 1.8V–16V range, no internal reference; requires external 400mV source or resistor divider. | Lacks integrated reference and Over-The-Top® inputs; needs additional components for same functionality and occupies more board area. | Choose only if existing design already uses external reference and 36V input tolerance is unnecessary. |
Compared with LT6700IS6-2#TRMPBF, the LT6700HVIS6-2#TRMPBF adds 36V input tolerance and AEC-Q100 qualification for automotive use; compared with TLV3702IDR, it reduces component count and improves accuracy by integrating the reference and hysteresis.

FAQ
What is the maximum input voltage rating for LT6700HVIS6-2#TRMPBF?
The LT6700HVIS6-2#TRMPBF supports input voltages from –0.3V to 36V relative to GND on both –INA and –INB pins, independent of the VS supply voltage. This Over-The-Top® capability allows direct connection to battery terminals or unregulated rails without level-shifting circuitry, making LT6700HVIS6-2#TRMPBF ideal for high-side monitoring in automotive and industrial systems.
Does LT6700HVIS6-2#TRMPBF require external hysteresis components?
No, LT6700HVIS6-2#TRMPBF includes internal hysteresis of 6.5mV typical, eliminating the need for external positive feedback resistors. This built-in feature ensures stable output operation near threshold crossings and simplifies design validation, especially in noisy environments where external hysteresis networks could introduce variability. The hysteresis value remains consistent across the full operating temperature range.
What is the operating temperature range of LT6700HVIS6-2#TRMPBF?
The LT6700HVIS6-2#TRMPBF is specified for operation from –40°C to +85°C and is AEC-Q100 qualified for automotive Grade I applications. This temperature range covers under-hood automotive electronics, industrial control cabinets, and outdoor instrumentation where ambient conditions exceed commercial-grade limits. The device maintains its key specifications-including reference accuracy and propagation delay-across this full range.
How does the 400mV internal reference improve system accuracy in LT6700HVIS6-2#TRMPBF?
The LT6700HVIS6-2#TRMPBF's internal 400mV reference contributes to ±1.25% max total threshold error at 25°C, combining reference drift, comparator offset, and hysteresis effects. Unlike external resistor dividers subject to ratio mismatch and temperature coefficient errors, this monolithic reference ensures consistent trip points across voltage scaling networks, reducing calibration overhead and improving batch-to-batch consistency in production.
Can LT6700HVIS6-2#TRMPBF drive a relay coil directly?
Yes, LT6700HVIS6-2#TRMPBF open-collector outputs sink ≥5mA over temperature and tolerate up to 36V off-state voltage, enabling direct drive of small relays (e.g., 12V/5mA coil) with appropriate pull-up. For higher-current relays, an external NPN transistor or MOSFET buffer is recommended. The output stage's guaranteed sinking capability and wide voltage tolerance make LT6700HVIS6-2#TRMPBF suitable for relay control in automotive and industrial systems without additional driver ICs.
