Product details
Overview
LT6700HVIS6-1#TRPBF 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 ±1.25% max threshold error at 25°C, and delivers open-collector outputs sinking >5mA - enabling battery-powered voltage supervision and window detection.
For engineers reviewing the LT6700HVIS6-1#TRPBF datasheet, LT6700HVIS6-1#TRPBF pinout, LT6700HVIS6-1#TRPBF application, or LT6700HVIS6-1#TRPBF equivalent, this part supports precise low-threshold detection with internal hysteresis (6.5mV typ), over-the-top input operation up to 36V, and AEC-Q100 qualification for automotive-grade reliability under –40°C to 85°C conditions.
Technical Context
The LT6700HVIS6-1#TRPBF integrates two independent comparators, each with one externally accessible input and the other tied internally to the 400mV reference. Its LT6700HV-1 variant provides one noninverting (+INA) and one inverting (–INB) input, enabling direct window comparator implementation without external resistors.
Input voltage range extends from GND – 0.3V to 36V regardless of supply voltage, supporting high-side sensing in systems with floating or elevated grounds. Output stages are open-collector with 36V absolute maximum off-state voltage rating and guaranteed 5mA sink capability across temperature.
Key Specifications

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#TRPBF | Same pinout and function but standard-voltage version (18V max input); not rated for 36V over-the-top operation. | Limited to systems where sensed voltage never exceeds 18V - unsuitable for automotive battery monitoring or high-side rail sensing. | Select when cost sensitivity outweighs 36V input requirement and ambient temperature stays ≤85°C. |
| TLV3701IDBVR | Single comparator with 1.24V reference; no internal hysteresis; 5.5V max supply; 650nA quiescent current. | Requires external hysteresis and resistor scaling; cannot implement window detection without additional comparators or logic. | Choose only for ultra-low-power single-threshold detection where 36V input and dual-channel operation are unnecessary. |
Compared with LT6700IS6-1#TRPBF and TLV3701IDBVR, the LT6700HVIS6-1#TRPBF uniquely combines 36V over-the-top inputs, dual-channel window capability, internal hysteresis, and AEC-Q100 qualification - making it the only drop-in solution for automotive and industrial high-reliability voltage supervision.
