Overview
The LT1716HS5#TRPBF is a micropower precision comparator in a 5-lead TSOT-23 package. It operates on supply voltages from 2.7V to 44V with a quiescent current of 35µA. The Over-The-Top input stage allows common mode voltages up to 44V above V–, independent of the positive supply. It features rail-to-rail output swing and an internal pull-up current source. The HS grade ensures functional performance across a temperature range of –40°C to 125°C.
Feature Summary
- Over-The-Top input capability extending 44V above the negative supply
- Micropower operation with 35µA quiescent current draw
- Rail-to-rail output swing with internal class B pull-up
- Automotive qualified AEC-Q100 compliant version available
Applications
- Power supply monitors
- Relay and lamp drivers
- Oscillators
- Peak detectors
- Level shifting circuits
Procurement Notes
Verify the specific HS suffix indicates the extended temperature range of –40°C to 125°C. Confirm the #TRPBF designation corresponds to tape and reel packaging. Ensure the component meets automotive reliability standards if required for the target application environment.
Selection Notes
Select this part when high voltage inputs exceed the local supply rail. The internal pull-up eliminates external resistors. Verify that the 35µA quiescent current fits system power budgets. Consider the TSOT-23 package constraints for thermal management and board space.
Part Context
This component belongs to the LT1716 family of comparators. The HS variant specifically denotes the industrial/high-temperature grade capable of operating up to 125°C. It shares the same electrical architecture as the C and I grades but offers wider thermal tolerance.
Replacement Considerations
LT1716IS5#TRPBF (Industrial Grade)
FAQ
Can the inputs withstand voltages below the negative supply?
Yes, built-in resistors protect the inputs for faults up to 5V below the negative supply without causing phase reversal.
Does the output require an external pull-up resistor?
No, the output stage includes an internal class B pull-up current source, eliminating the need for an external resistor.
