Overview
The LT6700MPDCB-3#TRMPBF is a micropower, low voltage dual comparator featuring an internal 400mV reference. It operates within a supply voltage range of 1.4V to 18V and draws a typical quiescent current of 6.5µA at 5V. The device utilizes a 6-lead DFN package and specifies an operating temperature range from -55°C to 125°C. Both comparator channels are configured with noninverting external inputs, while the opposing inputs connect internally to the reference. Outputs are open-collector type, supporting load voltages up to 18V independent of the supply rail.
Feature Summary
- Integrates two comparators with a fixed 400mV internal reference for simplified threshold detection
- Features noninverting external inputs on both channels suitable for window comparator configurations
- Open-collector outputs allow level translation to voltages independent of the supply voltage
- Includes internal hysteresis to ensure stable output operation without external components
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Automotive monitor and controls
Procurement Notes
Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces as per official documentation. Confirm the MP grade corresponds to the extended -55°C to 125°C temperature range. Ensure the DCB package matches the required footprint. Cross-reference the manufacturer part number against current availability status through authorized distributors.
Selection Notes
Select this variant when both comparator inputs require noninverting logic relative to the internal reference. The MP grade is necessary for applications requiring operation below -40°C. Verify that the open-collector output interface aligns with the downstream circuit requirements. Consider the DFN package dimensions if board space is constrained compared to SOT-23 alternatives.
Part Context
This component belongs to the LT6700 family of micropower comparators. The 'MP' designation identifies the automotive-grade temperature range extension. The '-3' suffix specifies the input polarity configuration with two noninverting inputs. The 'DCB' code denotes the 2mm x 3mm DFN package style. This specific ordering code combines these attributes into a single surface-mount device.

FAQ
What is the input polarity configuration for the LT6700MPDCB-3?
Both Comparator A and Comparator B have noninverting external inputs. The opposing inputs for each channel are 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, independent of the supply voltage used for the comparator core.
