Overview
The LM2901QDRDL is a quad automotive comparator from the LM2901-Q1 family, manufactured by Texas Instruments. It operates on a single or dual supply voltage ranging from 2V to 36V and functions within an ambient temperature range of -40°C to +125°C. The device features four independent differential voltage comparators with open-drain outputs compatible with TTL, MOS, and CMOS logic families. It is AEC-Q100 Grade 1 qualified, ensuring reliability for automotive environments.
Feature Summary
- AEC-Q100 Grade 1 qualification for automotive applications
- Wide supply voltage operation from 2V to 36V
- Open-drain outputs compatible with various logic families
- Differential input voltage range equal to maximum-rated supply voltage
Applications
- HEV/EV and power train systems
- Infotainment and cluster modules
- Body control modules
Procurement Notes
Verify the specific suffix 'DL' against the manufacturer's official orderable addendum to confirm package type and tape/reel specifications. Ensure the component meets the required AEC-Q100 Grade 1 standards for your target application. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement.
Selection Notes
Select this component when high supply voltage tolerance up to 36V is required alongside standard automotive qualification. The open-drain output allows flexible logic interfacing but requires external pull-up resistors. Consider the LM2901B-Q1 if lower offset voltage and bias current are critical, as the base LM2901-Q1 offers higher typical values.
Part Context
This part belongs to the LM2901-Q1 quadruple automotive comparator family. It serves as a robust alternative to general-purpose comparators in harsh environments. The family includes variants like LM2901V-Q1 and LM2901AV-Q1 with different voltage limits, while the LM2901B-Q1 offers enhanced precision metrics.
Replacement Considerations
LM2901QDR (non-automotive grade) may be used if automotive qualification is not required. LM2901BQDRQ1 offers improved electrical performance including lower offset voltage and bias current.
