LT6700CS6-3#TRMPBF

Overview

The LT6700CS6-3#TRMPBF is a micropower, low voltage dual comparator with an internal 400mV reference. It operates on a supply voltage from 1.4V to 18V and draws a typical quiescent current of 6.5µA at 5V. The device features two noninverting inputs (LT6700-3 configuration) with the other inputs tied internally to the reference. It includes internal hysteresis of approximately 6.5mV typical. Outputs are open-collector, allowing level translation up to 18V independent of the supply voltage. The component is housed in a 6-lead SOT-23 package and is specified for operation between 0°C and 70°C.

Feature Summary

• Integrates two comparators with a fixed 400mV internal reference threshold
• Features open-collector outputs capable of driving loads up to 18V independent of supply voltage
• Includes internal hysteresis to ensure stable output operation
• Supports wide supply voltage range from 1.4V to 18V with micropower consumption

Applications

• Battery-powered system monitoring
• Threshold detectors
• Window comparators
• Relay driving
• Industrial control systems
• Handheld instruments
• Automotive monitor and controls

Procurement Notes

Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 pieces. Confirm the CS6 designation corresponds to the commercial temperature grade of 0°C to 70°C. Ensure the -3 variant matches the required dual noninverting input configuration. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when a dual comparator with a fixed internal reference is required to minimize external components. The -3 suffix is necessary if both comparator inputs must be noninverting. Consider the SOT-23 package size for space-constrained designs. Verify that the 18V maximum input/output rating meets the application's voltage requirements, as higher voltages require the LT6700HV variant.

Part Context

This part belongs to the LT6700 family of micropower comparators. The LT6700 series offers multiple input polarity configurations (-1, -2, -3) and temperature grades (C, I, H, MP). The CS6 variant specifically denotes the commercial temperature range within the SOT-23 package form factor. It is designed for low-voltage applications where power efficiency and compact footprint are critical.

Replacement Considerations

Direct substitutes include other LT6700 variants with different temperature grades or input polarities, such as LT6700IS6-3#TRMPBF for industrial temperature range. For higher voltage tolerance, the LT6700HVIS6-3#TRMPBF is available. Ensure pin compatibility and electrical specifications match the original design requirements.
