Product details
Overview
LT6700HVHS6-2#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, two inverting inputs, open-collector outputs, 6.5µA supply current at 5V, and 36V output voltage capability. It operates from 1.4V to 18V supply and is rated for –40°C to 125°C, making it suitable for high-reliability automotive battery monitoring and industrial overvoltage detection.
For engineers reviewing the LT6700HVHS6-2#TRMPBF datasheet, LT6700HVHS6-2#TRMPBF pinout, LT6700HVHS6-2#TRMPBF application, or LT6700HVHS6-2#TRMPBF equivalent, key selection considerations include input polarity (dual inverting), HV-rated output swing (up to 36V), internal hysteresis (6.5mV typ), total threshold error (±1.25% max at 25°C), and AEC-Q100 qualification for automotive use.
Technical Context
The LT6700HVHS6-2#TRMPBF integrates two independent comparators, each with one externally accessible inverting input and the other internally tied to a precision 400mV reference. Its Over-The-Top® input architecture allows inputs to operate up to 36V above ground regardless of supply voltage.
Both open-collector outputs support sinking >5mA and tolerate off-state voltages up to 36V, enabling level translation and direct interface with higher-voltage loads such as relays or optocouplers without external components. Internal hysteresis eliminates need for external feedback networks.
Key Specifications

|---|---|
| Supply Voltage Range | 1.4V to 18V - supports single-cell Li-ion, multi-cell alkaline, and industrial 12V/15V rails. |
| Quiescent Current | 6.5µA typ at 5V - enables decade-long operation in battery-powered systems. |
| Reference Accuracy | ±1.25% max at 25°C - ensures precise, repeatable trip points without external trimming. |
| Hysteresis | 6.5mV typ - prevents output oscillation near threshold under noisy conditions. |
| Input Voltage Range | –0.3V to 36V - accommodates signals beyond supply rail, including negative transients and high-side sensing. |
| Output Sink Capability | >5mA over temperature - directly drives LEDs, small relays, or MOSFET gates. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
LT6700HVHS6-2#TRMPBF uses a 6-lead plastic TSOT-23 (S6) package with exposed pad not connected internally. Pin 7 is absent; the exposed thermal pad is optional for PCB connection and internally tied to GND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Open-collector output of comparator A - sinks current when input falls below 400mV reference. |
| 2 | GND | Ground reference for internal 400mV reference and comparator core - must be low-impedance return path. |
| 3 | –INA | Inverting input of comparator A - voltage applied here is compared against internal 400mV reference. |
| 4 | –INB | Inverting input of comparator B - enables dual-threshold detection with shared reference. |
| 5 | VS | Core supply voltage input - powers comparator circuitry and reference; independent of output voltage range. |
| 6 | OUTB | Open-collector output of comparator B - independently controlled, supports wired-OR logic or separate load control. |
