Overview
The LT1716HS5#WTRPBF is a micropower precision rail-to-rail 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 V+. It features a maximum input offset voltage of 30mV and an internal pull-up current source. This automotive-grade device supports temperatures from -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
- Internal class B pull-up current source eliminating external resistors
- Automotive qualified for high reliability requirements
Applications
- Power supply monitors
- Relay and lamp drivers
- Peak detectors
- Level shifting circuits
Procurement Notes
Verify the #W suffix indicates automotive qualification and specific manufacturing controls. Confirm the TRPBF suffix denotes tape and reel packaging. Ensure the HS5 grade matches the required -40°C to 125°C operating temperature range for your application environment.
Selection Notes
Select this part when inputs exceed the positive supply rail or require operation below the negative supply. The internal pull-up reduces component count compared to open-collector comparators. Verify that the 35µA quiescent current meets system power budgets.
Part Context
This component belongs to the LT1716 family of micropower comparators. The HS5 variant specifies the industrial/high-temperature grade (-40°C to 125°C). The W suffix designates automotive compliance, while TRPBF indicates reel packaging.

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 phase reversal.
Does the output require an external pull-up resistor?
No, the internal class B pull-up current source eliminates the need for an external resistive pull-up.
