Overview
The LT6700HDCB-2#TRMPBF is a micropower, low voltage dual comparator featuring an internal 400mV reference. It operates with supply voltages from 1.4V to 18V and draws only 6.5µA typical quiescent current at 5V. The device includes two inverting inputs and open-collector outputs capable of sinking greater than 5mA. Inputs and outputs operate up to 36V for the HV version, though this specific part is rated for 18V. It features internal hysteresis of 6.5mV typical and low input bias current of ±10nA maximum.
Feature Summary
- Integrates two micropower comparators with a fixed 400mV internal reference
- Features open-collector outputs allowing level translation independent of supply voltage
- Includes internal hysteresis to ensure stable output operation
- Supports Over-The-Top® input operation including ground potential
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific suffix #TRMPBF indicates mini tape and reel packaging containing 500 pieces. Confirm the DCB6 package designation matches the required 2mm x 3mm DFN footprint. Ensure the 'H' grade corresponds to the –40°C to 125°C specified temperature range for your application environment.
Selection Notes
Select this variant when two inverting comparator inputs are required relative to the internal reference. Compare against LT6700-1 or LT6700-3 if mixed polarity inputs are needed. Consider the LT6700HV series if input or output voltages must exceed 18V while maintaining the same low power characteristics.
Part Context
This component belongs to the LT6700/LT6700HV family of micropower comparators. It is available in commercial, industrial, and automotive temperature grades. The DCB6 package offers a tiny 2mm x 3mm form factor suitable for space-constrained designs requiring low profile surface mount technology.

FAQ
What is the function of the second input on each comparator section?
For the LT6700-2 variant, both inputs are inverting. One input is available externally, while the other is internally connected to the 400mV reference.
Can the output voltage exceed the supply voltage?
Yes, the open-collector outputs can be referred to any voltage up to 18V (or 36V for HV versions) independent of the supply voltage VS.
