Product details
Overview
LT6700HVIS6-2#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 features two inverting inputs, open-collector outputs rated to 36V, 6.5µA quiescent current at 5V, ±10nA max input bias current, and operates from 1.4V to 18V supply. It is used in battery voltage supervision and overvoltage/undervoltage detection circuits.
For engineers reviewing the LT6700HVIS6-2#TRPBF datasheet, LT6700HVIS6-2#TRPBF pinout, LT6700HVIS6-2#TRPBF application, or LT6700HVIS6-2#TRPBF equivalent, key selection considerations include its dual inverting-input configuration, 36V output voltage tolerance, –40°C to 85°C industrial temperature range, internal hysteresis (6.5mV typ), and SOT-23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The LT6700HVIS6-2#TRPBF implements two independent comparators, each with one externally accessible inverting input and the other internally tied to the precision 400mV reference. Its Over-The-Top® input architecture allows input voltages up to 36V regardless of supply voltage, enabling direct high-side sensing without level-shifting circuitry.
Both open-collector outputs support sinking >5mA over temperature and can be pulled up to any voltage ≤36V, decoupling output logic levels from the core supply. Internal hysteresis (6.5mV typical) eliminates oscillation near threshold without external components, simplifying design for stable trip-point detection.
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 |
|---|---|---|---|
| LT6700IS6-2#TRPBF | Same pinout and function but rated only to 18V input/output; no HV version. | Limited to ≤18V systems; unsuitable for 24V industrial or automotive battery monitoring. | Select LT6700IS6-2#TRPBF only if system maximum voltage is ≤18V and cost sensitivity outweighs HV margin. |
| TLV3702IDR | Single-supply dual comparator with 1.24V reference; no built-in hysteresis; 36V input not supported. | Requires external hysteresis resistors and reference scaling; less accurate threshold due to 1.24V reference tolerance. | Choose TLV3702IDR only when 400mV reference is unnecessary and board space allows external components. |

The LT6700HVIS6-2#TRPBF supports input voltages from –0.3V to 36V on both –INA and –INB pins, regardless of supply voltage (VS). This Over-The-Top® capability enables direct sensing of 24V industrial buses or automotive batteries without external attenuation, making LT6700HVIS6-2#TRPBF ideal for high-side monitoring applications where VS may be much lower than the monitored signal.
Does the LT6700HVIS6-2#TRPBF require external hysteresis components?
No, the LT6700HVIS6-2#TRPBF includes internal hysteresis of 6.5mV typical, eliminating the need for external positive-feedback resistors. This feature ensures stable output transitions near the 400mV reference threshold under noisy conditions, simplifying design and reducing bill-of-materials for LT6700HVIS6-2#TRPBF-based voltage supervisors.
What is the operating temperature range specified for the LT6700HVIS6-2#TRPBF?
The LT6700HVIS6-2#TRPBF is specified for operation from –40°C to +85°C, qualifying it for industrial-grade applications such as factory automation, motor drives, and outdoor equipment. This range is confirmed in the device's ordering information table and electrical characteristics section under the "I" grade designation, distinct from commercial (C) or high-temp (H) variants.
Can the LT6700HVIS6-2#TRPBF drive a relay coil directly?
Yes, the LT6700HVIS6-2#TRPBF open-collector outputs are guaranteed to sink >5mA over temperature and tolerate up to 36V off-state voltage. When paired with an appropriate pull-up resistor or external transistor driver, LT6700HVIS6-2#TRPBF can directly control low-power relays or interface with standard 5V/12V/24V logic inputs without additional buffering.
How does the LT6700HVIS6-2#TRPBF differ from the LT6700-2 variants without "HV" in the part number?
The "HV" suffix in LT6700HVIS6-2#TRPBF denotes high-voltage input/output capability: inputs and outputs tolerate up to 36V, whereas standard LT6700-2 variants (e.g., LT6700IS6-2#TRPBF) are limited to 18V. Both share identical pinout, 400mV reference, and dual inverting-input topology, but LT6700HVIS6-2#TRPBF is required for systems exceeding 18V rail monitoring.
