Product details
Overview
LT6700CS6-3#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for low-voltage system monitoring in battery-powered applications. It features two noninverting inputs, open-collector outputs rated to 18V, 6.5µA typical supply current at 5V, ±10nA max input bias current, and internal 6.5mV typical hysteresis - enabling robust threshold detection in handheld instruments and industrial controls.
For engineers reviewing the LT6700CS6-3#TRMPBF datasheet, LT6700CS6-3#TRMPBF pinout, LT6700CS6-3#TRMPBF application, or LT6700CS6-3#TRMPBF equivalent, this page delivers verified specifications, SOT-23-6 pin mapping, temperature-stable 400mV reference performance, and direct alternatives for window comparator or dual-threshold monitoring designs.
Technical Context
The LT6700CS6-3#TRMPBF implements two independent comparators, each with one externally accessible noninverting input (+INA, +INB) and the other internally tied to a precision 400mV reference. Its Over-The-Top® input architecture allows input voltages up to 18V regardless of supply voltage (1.4V–18V), supporting ground-referenced or high-side sensing.
Both open-collector outputs (OUTA, OUTB) sink ≥5mA and tolerate off-state voltages up to 18V, enabling level translation across domains. Internal hysteresis (6.5mV typ) eliminates external components for noise immunity in low-power threshold detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 18V - supports single-cell Li-ion, alkaline, and industrial rails without regulation. |
| Reference Voltage | 400mV ±1.25% max at 25°C - enables precise low-threshold detection without external resistors. |
| Quiescent Current | 6.5µA typ at 5V - extends battery life in always-on monitoring systems. |
| Input Bias Current | ±10nA max - minimizes error in high-impedance sensor interfaces. |
| Hysteresis | 6.5mV typ - provides built-in noise immunity; no external feedback required. |
| Output Sink Current | >5mA guaranteed over temperature - drives LEDs, MOSFET gates, or logic inputs directly. |

Pinout & Package
Package: 6-lead TSOT-23 (S6), 1mm profile, RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Battery Voltage Monitor | Industrial Threshold Detector |
|---|---|
Use Scenario: Monitoring alkaline AA cell voltage to detect end-of-life (<1.6V) while consuming <10µA total system current. IC Role / Device Role / Timing Role: Dual comparator compares battery voltage against 400mV reference via resistor dividers to generate low-battery flag and critical shutdown signal. Use Value: Micropower operation extends usable battery life; internal reference ensures consistent trip points across temperature and supply variation. | Use Scenario: Detecting overvoltage and undervoltage conditions on a 12V industrial bus with hysteresis to prevent relay chatter. IC Role / Device Role / Timing Role: LT6700CS6-3#TRMPBF configures as dual independent comparators - one for upper limit (e.g., 13.2V), one for lower limit (e.g., 10.8V) using same 400mV reference. Use Value: Eliminates need for two separate references or precision external resistors; 6.5µA quiescent current avoids loading sensitive bus nodes. |
| Handheld Instrument Power Sequencing | Automotive Cabin Sensor Interface |
Use Scenario: Enabling subsystem power-up only when main supply exceeds 3.0V and remains stable for >100ms in a portable multimeter. IC Role / Device Role / Timing Role: One comparator monitors supply rail; second provides timing delay via RC network on its output - leveraging open-collector outputs for wired-OR logic. Use Value: Integrated hysteresis and rail-to-rail input simplify sequencing design; SOT-23 package fits tight PCB layouts. | Use Scenario: Interfacing thermistor-based cabin temperature sensor to microcontroller ADC, with fault detection for open/short conditions. IC Role / Device Role / Timing Role: Comparators monitor sensor voltage against fixed thresholds derived from 400mV reference to flag out-of-range conditions before ADC sampling. Use Value: Input tolerance to –0.3V enables direct connection to grounded thermistor networks; low bias current preserves measurement accuracy. |
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 industrial temperature range; 14µA max supply current at 5V vs 11µA for LT6700CS6-3. | Required for extended-temperature industrial control panels or outdoor equipment where ambient exceeds 70°C. | Select when wider operating temperature range is mandatory; otherwise LT6700CS6-3#TRMPBF offers lower cost and identical performance in commercial environments. |
| TLV3702IDR | Single-supply dual comparator with 1.8V–16V range and internal 1.24V reference; no hysteresis; 1.2µA supply current; SOIC-8 package. | Lacks integrated hysteresis and fixed 400mV reference - requires external resistors for threshold setting and RC feedback for noise immunity. | Choose when ultra-low quiescent current (<2µA) is critical and board space allows SOIC-8; avoid if 400mV reference or built-in hysteresis is required. |
Compared with LT6700IS6-3#TRMPBF, the LT6700CS6-3#TRMPBF trades extended temperature support for lower cost and tighter initial reference accuracy; versus TLV3702IDR, it delivers integrated reference and hysteresis at the expense of higher quiescent current - making it optimal for precision, low-component-count threshold monitoring.

FAQ
What is the function of the LT6700CS6-3#TRMPBF in a battery-monitoring circuit?
The LT6700CS6-3#TRMPBF serves as a dual-threshold detector using its internal 400mV reference and two noninverting inputs. In battery monitoring, it compares divided battery voltage against fixed thresholds to generate early warning and critical shutdown signals - all while drawing only 6.5µA, preserving battery life. Its open-collector outputs interface directly with microcontroller GPIO or LED drivers.
Does the LT6700CS6-3#TRMPBF require external hysteresis components?
No, the LT6700CS6-3#TRMPBF includes internal hysteresis of 6.5mV typical, eliminating the need for external positive feedback resistors. This simplifies design, reduces component count, and ensures consistent noise immunity across temperature and supply voltage variations - critical for reliable operation in portable and industrial systems.
Can the LT6700CS6-3#TRMPBF operate with a 1.5V alkaline battery as its sole supply?
Yes, the LT6700CS6-3#TRMPBF operates down to 1.4V supply voltage, making it fully functional with a fresh 1.5V alkaline cell. At 1.4V, it maintains 6.5µA typical supply current and retains full input voltage range (–0.3V to 18V), enabling direct sensing of battery voltage without level shifting or regulation.
What is the maximum output sink current guaranteed for the LT6700CS6-3#TRMPBF?
The LT6700CS6-3#TRMPBF guarantees output sink current greater than 5mA over the full operating temperature range (0°C to 70°C). This allows direct driving of small relays, logic inputs, or indicator LEDs without external buffer transistors - simplifying power-domain interfacing in compact designs.
How does the LT6700CS6-3#TRMPBF differ from the LT6700-1 and LT6700-2 variants?
The LT6700CS6-3#TRMPBF has two noninverting inputs (+INA, +INB), whereas LT6700-1 offers one inverting and one noninverting input (for window comparator use), and LT6700-2 has two inverting inputs. This polarity configuration determines how external signals interface with the internal 400mV reference - LT6700CS6-3#TRMPBF is optimized for rising-edge detection on both channels.
