LM2903HYPT

Overview

The LM2903HYPT is a low-power dual voltage comparator manufactured by STMicroelectronics. It features two independent differential comparators in an 8-pin TSSOP surface-mount package. The device operates from a single power supply ranging from 2 V to 36 V, or dual supplies of ±1 V to ±18 V. Key electrical specifications include a maximum response time of 1.3 µs, a typical input offset voltage of 7 mV, and a quiescent supply current of 1 mA per channel. It supports output currents up to 16 mA and functions within a temperature range of -40°C to +150°C.

Feature Summary

• Dual differential voltage comparators designed for wide single-supply operation
• Input common-mode voltage range includes the negative supply rail
• Compatible with various logic families including CMOS, TTL, and ECL outputs
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive electronic systems requiring high-temperature reliability
• Industrial control circuits utilizing single-supply architectures
• Voltage monitoring and threshold detection tasks

Procurement Notes

Verify the specific suffix HYPT against official STMicroelectronics documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets the required AEC-Q100 qualification standards for your target application environment. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when designing systems that require operation at elevated temperatures up to 150°C. The H-series designation indicates extended thermal performance compared to standard industrial variants. Consider the TSSOP-8 package constraints for PCB layout and verify that the 1.3 µs propagation delay aligns with the system's switching speed requirements.

Part Context

This part belongs to the LM2903H series, which represents the high-temperature variant of the LM2903 family. While the standard LM2903 typically operates up to 125°C, the H-series extends the maximum junction temperature capability. This distinction is critical for automotive under-the-hood applications where ambient temperatures exceed standard industrial limits.
