Product details
Overview
LT6700HVIS6-1#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 operates from 1.4V to 18V supply, draws only 6.5µA typical quiescent current, features ±10nA max input bias current, 6.5mV typical hysteresis, and open-collector outputs rated to 36V (HV version), enabling robust threshold detection in battery-powered and wide-input systems.
For engineers reviewing the LT6700HVIS6-1#TRMPBF datasheet, LT6700HVIS6-1#TRMPBF pinout, LT6700HVIS6-1#TRMPBF application, or LT6700HVIS6-1#TRMPBF equivalent, this part supports precise window-comparator configurations with one inverting and one noninverting input, operates across –40°C to 85°C, and delivers stable 400mV reference accuracy (±1.25% max at 25°C) without external components.
Technical Context
The LT6700HVIS6-1#TRMPBF integrates two independent comparators sharing a precision internal 400mV reference; each has one externally accessible input while the other connects internally to the reference. Its LT6700-1 variant configuration provides +INA (noninverting) and –INB (inverting) inputs, enabling direct window-comparator implementation without external resistors.
Input voltage range extends to 36V (relative to GND), independent of supply voltage, supporting Over-The-Top® operation down to ground. Open-collector outputs sink >5mA over temperature and tolerate up to 36V pull-up, allowing level translation and interface with higher-voltage logic or relay drivers.
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 - ensures multi-year battery life in always-on monitoring circuits. |
| Reference Accuracy | ±1.25% max at 25°C - eliminates need for external trimming in cost-sensitive threshold detection. |
| Hysteresis | 6.5mV typ - prevents output oscillation near trip points without external feedback components. |
| Input Bias Current | ±10nA max - permits high-impedance sensing (e.g., resistor-divider networks >1MΩ) without significant error. |
| Output Voltage Range | Up to 36V (vs GND) - allows direct drive of 24V PLC inputs or optocouplers without level-shifting circuitry. |
| Operating Temp | –40°C to 85°C - qualified for industrial control and under-hood automotive environments. |
Pinout & Package
Package: 6-lead plastic TSOT-23 (S6), 1mm profile, RoHS-compliant, tape-and-reel (500 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output of Comparator A | Sinks >5mA; off-state voltage up to 36V - drives LEDs, MOSFET gates, or optocouplers directly. |
| GND | Ground reference and reference low side | Common return for supply, reference, and signal paths; exposed pad optional in DFN but not present in SOT-23. |
| +INA | Noninverting input of Comparator A | Accepts –0.3V to 36V; used with internal 400mV reference to detect rising thresholds (e.g., battery OK). |
| OUTB | Open-collector output of Comparator B | Independent output with same 36V capability as OUTA - enables dual-threshold or window logic. |
| VS | Core supply voltage | Powers internal comparators and reference; decoupling capacitor required at pin for stability. |
| –INB | Inverting input of Comparator B | Accepts –0.3V to 36V; compares against internal 400mV reference to detect falling thresholds (e.g., undervoltage lockout). |
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. |
| Over-The-Top® input operation | Supports input signals down to –0.3V and up to 36V regardless of VS - enables direct sensing of battery, bus, or sensor voltages without level shifters. |
| Internal hysteresis | 6.5mV typical - removes need for external positive feedback resistors, simplifying design and improving noise immunity. |
| Low input bias current | ±10nA max - preserves accuracy in high-impedance divider networks used for high-voltage monitoring (e.g., 48V systems). |
| Wide temperature range | –40°C to 85°C operation - meets industrial and automotive ambient requirements without derating or thermal compensation. |
Applications
| Battery Voltage Monitor | Industrial Undervoltage Lockout |
|---|---|
Use Scenario: Monitoring single-cell Li-ion (2.5V–4.2V) or alkaline (0.9V–1.6V) battery voltage to trigger low-battery warning or shutdown. IC Role / Device Role / Timing Role: Dual comparator implements high-threshold (battery OK) and low-threshold (battery critical) detection using internal 400mV reference and resistor dividers. Use Value: 6.5µA quiescent current extends battery life; ±1.25% reference accuracy ensures consistent trip points across temperature and unit variance. | Use Scenario: Detecting brownout conditions on 12V or 24V industrial power rails before microcontroller reset or actuator failure. IC Role / Device Role / Timing Role: LT6700HVIS6-1#TRMPBF acts as dedicated UVLO supervisor, asserting fault signal when rail drops below programmable threshold. Use Value: 36V input tolerance allows direct connection to unregulated rails; open-collector outputs interface cleanly with PLC or FPGA inputs. |
| Automotive Window Comparator | Handheld Instrument Threshold Detector |
Use Scenario: Validating sensor output (e.g., pressure transducer) stays within safe operating band in ADAS or body control modules. IC Role / Device Role / Timing Role: Configured as window comparator using +INA and –INB pins to assert fault only when signal falls outside defined upper/lower bounds. Use Value: Single-chip solution replaces discrete op-amp + reference + resistors; AEC-Q100-compatible temperature range ensures reliability in vehicle environments. | Use Scenario: Detecting pass/fail status of analog sensor readings (e.g., thermistor, photodiode) in portable test equipment with limited PCB area. IC Role / Device Role / Timing Role: Provides fast, low-power threshold comparison with minimal external components - ideal for battery-operated handheld devices. Use Value: TSOT-23 package fits tight layouts; 1.4V minimum supply enables operation from partially discharged batteries during field use. |
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 | Same pinout and function, but standard voltage rating (18V max input/output) instead of 36V HV rating. | Not suitable for >18V input monitoring or 24V+ pull-up applications; lower absolute maximum ratings limit use in industrial 24V/48V systems. | Select when system voltages remain ≤18V and cost sensitivity outweighs HV margin. |
| TLV3701IDBVR | Single comparator with 1.24V reference, 650nA quiescent current, no internal hysteresis, SOT-23-6 package. | Requires external hysteresis and resistor network for dual-threshold; lacks integrated 400mV reference and Over-The-Top® input capability. | Choose only for ultra-low-power single-threshold detection where reference flexibility justifies added design complexity. |
Compared with LT6700IS6-1#TRMPBF, the LT6700HVIS6-1#TRMPBF adds 36V input/output tolerance essential for industrial 24V systems; versus TLV3701IDBVR, it delivers integrated dual-comparator architecture with factory-trimmed hysteresis and reference - reducing component count and validation effort by eliminating external passive networks.
