Overview
The TS391RIYLT is a low-power, single voltage comparator manufactured by STMicroelectronics. It operates from a wide single supply range of 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features very low supply current of 0.2 mA independent of supply voltage and low input bias current of 25 nA typical. Input common-mode voltage includes ground even with single supply operation. It is qualified to AEC-Q100 standards for automotive applications and housed in an SOT-23-5 package.
Feature Summary
- Designed for low-power voltage comparison with wide single or dual supply voltage ranges
- Input common-mode voltage range includes ground during single supply operation
- Qualified for automotive applications according to AEC-Q100 standards
- Outputs are compatible with TTL, DTL, ECL, and CMOS logic families
Applications
- Automotive electronic systems requiring AEC-Q100 qualified components
- Voltage monitoring circuits operating from single power supplies
- Threshold detection and level shifting interfaces
- Battery management system protection circuits
Procurement Notes
Verify the specific ordering suffix RIYLT corresponds to the automotive grade SOT-23-5 package variant. Confirm that the component meets AEC-Q100 qualification requirements for your target application environment. Ensure compatibility with the required temperature range of -40 °C to 125 °C. Check datasheet specifications for absolute maximum ratings before integration.
Selection Notes
Select this component when automotive reliability and low power consumption are critical. The wide supply voltage range supports various system architectures. Ground-referenced input capability simplifies circuit design for single-supply applications. Verify output drive requirements against load conditions to ensure proper signal levels.
Part Context
This part belongs to the TS391 family of low-power comparators. It shares core electrical characteristics with standard variants but includes automotive-grade screening and qualification. The RIYLT designation indicates the specific packaging and quality tier within the broader product line.
Replacement Considerations
TS391IYLT serves as a direct alternative within the same automotive-grade series. TS391RILT offers similar performance in standard commercial grade. Verify pinout compatibility and electrical parameter alignment before substitution.
