Product details
Overview
LT6700HS6-1#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for low-voltage system monitoring in harsh environments. It features one inverting and one noninverting input (enabling window comparator operation), 6.5µA supply current at 5V, ±10nA max input bias current, and operates from 1.4V to 18V supply across –40°C to 125°C.
For engineers reviewing the LT6700HS6-1#TRMPBF datasheet, LT6700HS6-1#TRMPBF pinout, LT6700HS6-1#TRMPBF application, or LT6700HS6-1#TRMPBF equivalent, this part supports precision threshold detection in automotive battery monitors, industrial control systems, handheld instruments, and relay driving circuits where wide supply range, internal hysteresis, and high-temperature reliability are critical.
Technical Context
The LT6700HS6-1#TRMPBF integrates two independent comparators sharing a single 400mV internal reference; each comparator has one externally accessible input while the other connects internally to the reference. Its open-collector outputs support level translation up to 18V (independent of VS) and sink >5mA over temperature.
Input polarity configuration is fixed per variant: LT6700HS6-1#TRMPBF provides +INA and –INB, enabling asymmetric window detection. Internal hysteresis (6.5mV typ) eliminates external feedback components and ensures stable output transitions under noisy conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.4V to 18V - enables direct operation from single-cell Li-ion or multi-cell alkaline batteries without regulation. |
| Quiescent Current | 6.5µA typ at 5V - allows years of operation on coin cells in always-on monitoring applications. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures reliable trip-point consistency without calibration. |
| Hysteresis | 6.5mV typ - suppresses chatter on slow or noisy inputs without requiring external resistor networks. |
| Input Bias Current | ±10nA max - permits use with high-impedance sensor dividers (e.g., >1MΩ) without significant voltage error. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive and industrial embedded environments. |
| Output Sink | >5mA guaranteed - directly drives LEDs, small relays, or logic inputs without external buffers. |
Pinout & Package
Package: 6-lead TSOT-23 (S6), 1mm profile, RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output of Comparator A | Sinks current when active; off-state voltage can reach 18V regardless of VS - enables level-shifting to higher rail logic. |
| GND | Ground reference and reference low-side | Common return for internal 400mV reference and all circuitry; must be connected for proper reference operation. |
| +INA | Noninverting input of Comparator A | Accepts input from –0.3V to 18V vs GND; used with internal 400mV reference to detect rising thresholds. |
| OUTB | Open-collector output of Comparator B | Independent output with same sinking capability and voltage tolerance as OUTA. |
| VS | Core supply voltage | Powers comparator core and reference; no internal regulation - supply must be within 1.4V–18V range. |
| –INB | Inverting input of Comparator B | Accepts input from –0.3V to 18V vs GND; used with internal 400mV reference to detect falling thresholds. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400mV reference | Eliminates need for external reference IC or resistor divider, reducing BOM count and layout area. |
| Internal hysteresis | 6.5mV typical - removes requirement for external positive feedback resistors and associated design iteration. |
| Over-the-Top® input capability | Inputs operate down to –0.3V and up to 18V regardless of VS - supports ground-referenced or high-side sensing without level shifters. |
| Wide temperature grade | –40°C to 125°C operation with full specification - suitable for automotive engine control units and industrial PLC modules. |
| Low input bias current | ±10nA max - preserves accuracy in high-impedance voltage divider networks used for battery voltage monitoring. |

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 functionality but rated for –40°C to 85°C industrial range; lower max operating temperature. | Not qualified for under-hood automotive or high-temp industrial enclosures. | Select when ambient temperature stays below 85°C and cost sensitivity outweighs extended temperature margin. |
| TLV3701IDBVR | Single comparator with 1.24V reference, 1.8V–16V supply, 1.1µA quiescent current - lacks dual channel and 400mV reference. | Requires two devices and external resistor scaling to emulate window function; no built-in hysteresis. | Choose only if ultra-low power (<2µA) is mandatory and dual-channel integration is not required. |
Compared with LT6700IS6-1#TRMPBF, the LT6700HS6-1#TRMPBF adds 40°C higher maximum junction temperature and AEC-Q100 alignment for automotive use; compared with TLV3701IDBVR, it delivers integrated dual-channel window detection with tighter reference accuracy and guaranteed hysteresis - eliminating design overhead for robust threshold monitoring.

FAQ
What is the reference voltage accuracy of the LT6700HS6-1#TRMPBF over temperature?
The LT6700HS6-1#TRMPBF features a total threshold error of ±1.25% maximum at 25°C. Over its full –40°C to 125°C operating range, the rising input threshold voltage varies by less than ±3mV (from 390mV to 411mV), ensuring consistent trip points in automotive and industrial environments without calibration.
Can the LT6700HS6-1#TRMPBF operate from a 1.4V supply while driving a 5mA load?
Yes - the LT6700HS6-1#TRMPBF is fully specified down to 1.4V supply and guarantees >5mA output sink capability across temperature. At 1.4V, VOL is 250mV max at 0.1mA load; for 5mA loads, a higher VS (≥1.6V) is recommended to maintain <200mV saturation voltage, as confirmed in the Electrical Characteristics table.
How does the input polarity configuration of LT6700HS6-1#TRMPBF enable window comparator functionality?
The LT6700HS6-1#TRMPBF has +INA (noninverting) and –INB (inverting) inputs. When both comparators share the same 400mV reference, +INA detects rising input crossings above the threshold, while –INB detects falling crossings below it - forming a complete window detector with a single device and no external inversion.
Is the LT6700HS6-1#TRMPBF pin-compatible with other LT6700 variants in the SOT-23 package?
Yes - all LT6700xS6-x variants (including LT6700HS6-1#TRMPBF, LT6700IS6-1#TRMPBF, and LT6700CS6-1#TRMPBF) share identical 6-lead TSOT-23 pinout and footprint. Input polarity differs between -1, -2, and -3 versions, but mechanical and electrical connectivity remains consistent across temperature grades.
Does the LT6700HS6-1#TRMPBF require external hysteresis components?
No - the LT6700HS6-1#TRMPBF includes internal hysteresis of 6.5mV typical (2mV to 13.5mV over temperature). This eliminates the need for external positive feedback resistors, simplifying design and improving noise immunity in battery monitor and industrial sensor interfaces.
