Product details
Overview
LT6700HVIS6-3#TRMPBF 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 noninverting 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.
For engineers reviewing the LT6700HVIS6-3#TRMPBF datasheet, LT6700HVIS6-3#TRMPBF pinout, LT6700HVIS6-3#TRMPBF application, or LT6700HVIS6-3#TRMPBF equivalent, this part supports precision threshold detection with ±1.25% max total threshold error at 25°C, internal hysteresis (6.5mV typ), and Over-The-Top® input capability down to ground - critical for battery voltage supervision and fault monitoring in harsh environments.
Technical Context
The LT6700HVIS6-3#TRMPBF integrates 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 36V regardless of supply voltage, enabling direct sensing of high-side rails without level-shifting.
Both open-collector outputs (OUTA, OUTB) sink ≥5mA over temperature and tolerate off-state voltages up to 36V, supporting flexible level translation and relay driving. Internal hysteresis (6.5mV typical) eliminates external components for stable switching in noisy environments, while the –40°C to 85°C industrial temperature range ensures reliability in embedded control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 1.4V to 18V - enables operation from single-cell Li-ion or alkaline batteries up to industrial 12V/15V rails. |
| Quiescent Current | 6.5µA typ at 5V - supports multi-year battery life in always-on monitoring circuits. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures precise, repeatable trip points without calibration. |
| Input Voltage Range | –0.3V to 36V relative to GND - permits direct sensing of battery, bus, or sensor signals exceeding VS. |
| Hysteresis | 6.5mV typ - suppresses chatter on slow or noisy input edges without external resistors. |
| Output Sink Current | ≥5mA guaranteed over temperature - drives LEDs, MOSFET gates, or small relays directly. |
| Input Bias Current | ±10nA max - minimizes voltage drop across high-impedance divider networks (e.g., 1MΩ+). |
Pinout & Package
LT6700HVIS6-3#TRMPBF uses a 6-lead TSOT-23 (S6) package, 2.9mm × 1.6mm × 1.0mm profile, with exposed pad thermally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output A | Sinks ≥5mA; off-state voltage up to 36V - interfaces directly with 3.3V/5V/12V logic or 24V loads. |
| GND | Ground reference | Common return for internal 400mV reference and output pull-down paths; exposed pad must be soldered for thermal performance. |
| +INA | Noninverting input A | Accepts –0.3V to 36V; compares against internal 400mV reference - used for high-side voltage monitoring. |
| OUTB | Open-collector output B | Independent of OUTA; enables dual-threshold or window detection with shared reference. |
| VS | Core supply voltage | Powers comparator core only; does not limit input/output voltage ranges - decoupling capacitor required. |
| +INB | Noninverting input B | Identical electrical behavior to +INA; allows simultaneous monitoring of two independent signals against same 400mV threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Dual noninverting-input topology | Enables direct high-side sensing of two independent rails (e.g., VBAT and VCORE) without inversion logic or external op-amps. |
