Overview
The LM2901HYDT is an automotive-grade, low-power quad voltage comparator manufactured by STMicroelectronics. It features four independent precision comparators designed for single or split power supply operation within a range of +2 V to +36 V. The device operates over an extended temperature range from -40 °C to +150 °C and is housed in a SO-14 plastic micropackage. Key electrical characteristics include a typical supply current of 1.1 mA, input bias current of 25 nA, and small signal response time of 1.3 μs. It meets AEC-Q100 qualification standards.
Feature Summary
- Automotive grade qualification compliant with AEC-Q100 standards
- Extended operating temperature range up to +150 °C
- Low power consumption with supply current independent of voltage
- Input common-mode voltage range includes ground
Applications
- Automotive electronic systems requiring high reliability
- High temperature industrial control applications
- Voltage monitoring circuits in harsh environments
Procurement Notes
Verify the specific ordering code matches the required package and packing configuration. Confirm that the automotive grade designation aligns with project requirements. Ensure compatibility with the intended supply voltage and temperature conditions. Check for any specific screening requirements defined by AEC-Q standards before finalizing procurement.
Selection Notes
Select this component when high temperature stability and automotive reliability are critical. The wide supply voltage range supports diverse power architectures. Consider the SO-14 package dimensions for PCB layout constraints. Evaluate the low input bias current for high impedance sensor interfaces.
Part Context
This part belongs to the LM2901H series of high temperature, low-power quad voltage comparators. It shares core functionality with standard versions but includes enhanced screening and qualification for automotive use. The family offers flexibility through various package options and temperature grades.
Replacement Considerations
LM2901HDT serves as a non-automotive equivalent. Verify if the standard grade meets the thermal and reliability requirements of the application.
