Overview
The LM2903BYPT is a dual low-power voltage comparator manufactured by STMicroelectronics, designed for operation from a single supply over a wide voltage range or split power supplies. It features an input common-mode voltage range that includes the negative rail. The device offers very low supply current of 0.4 mA independent of supply voltage and low input bias current of 25 nA typical. It provides TTL, DTL, ECL, MOS, and CMOS compatible outputs with a differential input voltage range equal to the supply voltage. The component is qualified under AEC-Q100 standards.
Feature Summary
- Dual low-power voltage comparators designed for wide single-supply or split power supply operation
- Input common-mode voltage range includes the negative power rail
- Outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic families
- Qualified for automotive applications under AEC-Q100 standards
Applications
- Automotive electronic systems requiring voltage monitoring
- General-purpose analog signal comparison circuits
- Power supply management and protection interfaces
Procurement Notes
Verify the specific suffix BYPT against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure the AEC-Q100 qualification status aligns with your system requirements. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current production status before procurement.
Selection Notes
Select this component when dual comparators are required in a compact surface-mount package with automotive qualification. Consider its low supply current and wide voltage range for battery-powered or energy-efficient designs. Verify that the output compatibility meets the interface requirements of the downstream logic circuitry.
Part Context
This device belongs to the LM2903 series of analog comparators from STMicroelectronics. It shares functional similarities with other members like the LM2903YQ3T but differs in packaging and specific automotive grade qualifications. The series is characterized by low power consumption and robust performance across varying supply voltages.
