Overview
The LT1716HS5#WTRMPBF 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 device features an Over-The-Top input stage allowing common mode voltages up to 44V above V–, independent of V+. It provides rail-to-rail output swing and can drive loads connected to supplies higher than the device supply. The HS5 variant supports an operating 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 pull-up current source
- Automotive qualified version with controlled manufacturing
Applications
- Power supply monitors
- Relay and lamp drivers
- Oscillators
- Peak detectors
- Level shifting circuits
Procurement Notes
Verify that the specific suffix #WTRMPBF corresponds to the Automotive grade (HS5) variant with tape and reel packaging. Confirm the manufacturer's automotive reliability reports are obtained for your specific application requirements. Ensure the ordering information matches the required temperature range and package type.
Selection Notes
Select this component when high voltage inputs exceeding the positive supply rail are expected. The rail-to-rail output eliminates the need for external pull-up resistors. Verify that the 35µA quiescent current meets system power constraints. Ensure the TSOT-23 package fits the available board space.
Part Context
This part belongs to the LT1716 family of micropower comparators. The 'H' indicates the extended temperature grade (-40°C to 125°C). The '#W' suffix denotes automotive qualification. The '#TRMPBF' indicates tape and reel packaging without lead-free finish restrictions beyond standard RoHS compliance.
Replacement Considerations
LT1716CS5#TRPBF: Standard industrial grade (-40°C to 85°C), not automotive qualified.
FAQ
Can the inputs withstand voltages below the negative supply?
Yes, if one input is within the valid range, the other can go up to 5V below V– without phase reversal.
Does the output require an external pull-up resistor?
No, the output stage includes an internal class B pull-up current source.
