Overview
The LT6700HS6-2#WTRPBF is a micropower, low voltage dual comparator with an internal 400mV reference. It operates on supply voltages from 1.4V to 18V and draws approximately 6.5µA at 5V. The device features two inverting inputs and open-collector outputs capable of sinking over 5mA. Inputs and outputs operate up to 36V for the HV variant, though this specific part is standard voltage rated to 18V. It is specified for operation from -40°C to 125°C.
Feature Summary
- Integrates two 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 wide supply range from 1.4V to 18V
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Automotive monitor and controls
Procurement Notes
Verify the automotive grade designation indicated by the #W suffix against project requirements. Confirm the HS6 package variant matches the thermal and physical constraints of the target PCB layout. Ensure the operating temperature range of -40°C to 125°C aligns with environmental specifications. Cross-reference the datasheet revision to confirm electrical characteristics match design calculations.
Selection Notes
Select this component when a dual comparator with a fixed reference is required in a small SOT-23 package. The -2 suffix indicates both inputs are inverting, suitable for specific threshold logic configurations. Consider the LT6700HV variants if input or output voltages exceed 18V. Evaluate quiescent current consumption against battery life requirements for portable applications.
Part Context
This part belongs to the LT6700 family of micropower comparators. The HS6 designation specifies the industrial/high-temperature grade (-40°C to 125°C) in a 6-lead TSOT-23 package. The -2 suffix denotes the pinout configuration with two inverting inputs. The #W suffix indicates automotive qualification under AEC-Q100 standards.

FAQ
What is the polarity of the external inputs for the LT6700HS6-2?
The LT6700-2 variant features two inverting inputs. 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 used.
