Product details
Overview
LT6700MPS6-3#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, configured with two noninverting inputs for threshold detection in ultra-low-power systems. It operates from 1.4V to 18V supply, draws only 6.5µA typical quiescent current at 5V, features 6.5mV typical hysteresis, and supports input voltages up to 36V (Over-The-Top®), making it ideal for battery voltage monitoring in aerospace-grade embedded systems.
For engineers reviewing the LT6700MPS6-3#TRMPBF datasheet, LT6700MPS6-3#TRMPBF pinout, LT6700MPS6-3#TRMPBF application, or LT6700MPS6-3#TRMPBF equivalent, this page delivers verified electrical specs, temperature-range-validated performance data, SOT-23 package layout guidance, and real-world design context for high-reliability analog sensing circuits.
Technical Context
The LT6700MPS6-3#TRMPBF integrates two independent comparators sharing a precision 400mV internal reference; each comparator's second input is hardwired to that reference, while the external pins (+INA, +INB) accept noninverting signals. This architecture enables simultaneous high-side and low-side threshold detection without external resistive dividers.
Its open-collector outputs (OUTA, OUTB) support rail-to-rail sinking up to 5mA and tolerate off-state voltages up to 36V-decoupled from VS-enabling level translation across disparate supply domains. Internal hysteresis (6.5mV typ) eliminates oscillation near trip points without external feedback components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 18V - Enables operation directly from single-cell Li-ion or multi-cell alkaline stacks without regulation. |
| Quiescent Current | 6.5µA typ at 5V - Supports >10-year battery life in always-on monitoring applications. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - Ensures precise, repeatable trip points without calibration. |
| Hysteresis | 6.5mV typ - Eliminates noise-induced chatter on slow-rising/falling inputs without external RC networks. |
| Input Voltage Range | –0.3V to 36V - Allows direct connection to unregulated rails or battery terminals, even when VS is low. |
| Output Sink Current | >5mA guaranteed over temperature - Drives LEDs, MOSFET gates, or optocouplers directly without buffer stages. |
| Operating Temp Range | –55°C to 125°C - Qualified for extended industrial, automotive, and aerospace environments. |
Pinout & Package
LT6700MPS6-3#TRMPBF is housed in a 6-lead plastic TSOT-23 (S6) package, 2.9mm × 1.6mm × 1.0mm profile, with exposed pad thermally connected to GND. Pin 1 = OUTA, Pin 2 = GND, Pin 3 = +INA, Pin 4 = +INB, Pin 5 = VS, Pin 6 = OUTB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Open-collector output of Comparator A | Sinks current when +INA exceeds 400mV; supports pull-up to 36V independent of VS. |
| GND (Pin 2) | Ground reference and reference low terminal | Common return for internal 400mV reference and all circuitry; must be low-impedance. |
| +INA (Pin 3) | Noninverting input of Comparator A | Accepts signals from –0.3V to 36V; comparator trips high when input > 400mV reference. |
| +INB (Pin 4) | Noninverting input of Comparator B | Independent noninverting input; enables dual-threshold detection (e.g., under/over-voltage). |
| VS (Pin 5) | Core supply voltage | Powers comparator core and reference; range 1.4V–18V; does not limit input/output voltage swing. |
| OUTB (Pin 6) | Open-collector output of Comparator B | Functionally identical to OUTA; allows independent control of two external loads. |
Key Features
| Feature | Design Value |
|---|---|
| Dual noninverting inputs | Enables simultaneous high-side threshold detection on both comparators without polarity inversion circuitry. |
| Integrated 400mV reference | Eliminates need for external precision reference IC or resistor divider, reducing BOM count and layout area. |

| Guaranteed >5mA sink per output | Drives standard logic-level MOSFETs or optocouplers directly, removing gate-driver or transistor buffer stages. |
| –55°C to 125°C operation | Validated performance across extreme ambient conditions, supporting MIL-STD-810G and DO-160D compliance paths. |
Applications
| Battery Under-Voltage Lockout | Power Supply Sequencing Monitor |
|---|---|
Use Scenario: Detecting when a lithium-thionyl chloride primary cell drops below 2.8V to disable non-critical subsystems before deep discharge. IC Role / Device Role / Timing Role: LT6700MPS6-3#TRMPBF compares battery voltage against 400mV reference via resistive divider; its dual outputs enable separate enable/disable control paths.

| Industrial Sensor Fault Detection | Aerospace Battery Cell Balancing Enable |
Use Scenario: Identifying open-circuit or short-circuit faults in 4–20mA loop transmitters by monitoring loop compliance voltage. IC Role / Device Role / Timing Role: LT6700MPS6-3#TRMPBF senses loop voltage at two thresholds (e.g., 12V OK / 24V fault) using its dual noninverting inputs and shared reference. Use Value: Delivers deterministic fault response in <30µs propagation delay, with no external hysteresis components needed. | Use Scenario: Enabling passive balancing FETs only when individual Li-ion cell voltage exceeds 4.15V during charging cycles.

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 |
|---|---|---|---|
| LT6700IS6-3#TRMPBF | Same functionality but rated for –40°C to 85°C; lower cost; 13µA max IS vs 13µA typ for MP grade. | Lacks extended low-temp capability; unsuitable for cold-soak or space-grade deployments. | Select when operating range is limited to commercial/industrial environments and cost sensitivity outweighs extreme temp coverage. |
| TLV3702IDR | Single-supply dual comparator with 1.24V reference; no Over-The-Top® input; 1.8V–16V supply; 800nA IQ. | Cannot monitor voltages above VS; requires external scaling for >16V rails; lacks guaranteed 5mA sink. | Choose only for ultra-low-power (<1µA) applications where input voltage stays below VS and reference flexibility is secondary. |
Compared with LT6700IS6-3#TRMPBF, the LT6700MPS6-3#TRMPBF provides validated operation down to –55°C and tighter initial threshold accuracy, enabling deployment in cryogenic or high-reliability aerospace systems; versus TLV3702IDR, it delivers 36V input tolerance and robust 5mA output drive-critical for direct interface with industrial actuators and unregulated battery stacks.

FAQ
What is the maximum input voltage rating for LT6700MPS6-3#TRMPBF?
The LT6700MPS6-3#TRMPBF supports input voltages from –0.3V to 36V relative to GND on both +INA and +INB pins, regardless of the VS supply voltage. This Over-The-Top® capability allows direct monitoring of battery stacks or unregulated rails without level-shifting circuitry, and is fully specified across the –55°C to 125°C operating range.
Does LT6700MPS6-3#TRMPBF require external hysteresis components?
No, the LT6700MPS6-3#TRMPBF includes internal hysteresis of 6.5mV typical (3.5mV min, 9.5mV max), which is factory-trimmed and temperature-stable. This eliminates the need for external positive-feedback resistors, simplifying PCB layout and ensuring consistent noise immunity across all operating conditions without design iteration.
Can LT6700MPS6-3#TRMPBF drive a MOSFET gate directly?
Yes, the LT6700MPS6-3#TRMPBF open-collector outputs (OUTA and OUTB) guarantee >5mA sink current over temperature and support pull-up voltages up to 36V. This enables direct driving of logic-level N-channel MOSFET gates (e.g., Si2302, DMN2004) without buffer transistors, provided the gate charge and switching frequency align with the 29µs low-to-high propagation delay.
What is the reference voltage accuracy of LT6700MPS6-3#TRMPBF over temperature?
The LT6700MPS6-3#TRMPBF features a total threshold error of ±1.25% maximum at 25°C, with drift characterized across –55°C to 125°C. Typical rising threshold variation is ±2mV over full temperature range (398mV to 402mV), ensuring reliable trip-point stability in unheated enclosures or high-ambient environments without recalibration.
Is LT6700MPS6-3#TRMPBF pin-compatible with other LT6700 variants?
Yes, all LT6700 SOT-23 variants-including LT6700MPS6-3#TRMPBF, LT6700IS6-3#TRMPBF, and LT6700HS6-3#TRMPBF-share identical 6-pin TSOT-23 pinout and footprint. The only differences are temperature grade, initial accuracy, and quiescent current specifications; no PCB redesign is required when upgrading or substituting within the same -3 variant.
