Overview
The LM2903AVQPWRDL is a dual differential voltage comparator from the LM2903-Q1 family, designed for automotive and industrial applications. It operates on single or dual supplies ranging from 2V to 36V. The device features an open-drain output compatible with TTL, MOS, and CMOS logic. It includes two independent comparators with a common-mode input voltage range that includes ground. The component is AEC-Q100 qualified for Grade 1 temperature operation (-40°C to +125°C) and offers functional safety capability.
Feature Summary
- AEC-Q100 qualified for Grade 1 automotive reliability standards
- Open-drain outputs allow flexible logic level shifting and wired-AND configurations
- Wide supply voltage range supports operation from 2V up to 36V
- Common-mode input voltage range extends down to ground potential
Applications
- Automotive HEV/EV power train systems
- Infotainment and instrument cluster circuits
- Body control module signal processing
- Industrial sensor interface applications
- Appliance control logic
Procurement Notes
Verify the specific suffix 'DL' against the manufacturer's official orderable addendum to confirm package type and availability. Ensure the selected variant meets the required AEC-Q100 grade and temperature specifications for the target application environment. Cross-reference the part number with the latest datasheet revision history to confirm pinout and electrical characteristics have not changed.
Selection Notes
Select this component when high voltage tolerance up to 36V is required alongside low supply current consumption. The open-drain architecture is suitable for interfacing with microcontrollers operating at different logic levels. Consider the thermal resistance metrics in the datasheet for PCB layout planning to ensure reliable operation within the specified ambient temperature range.
Part Context
This device belongs to the LM2903-Q1 family of dual comparators, which are industry-standard replacements for legacy parts like the LM2903. The family provides robust performance in noisy environments with high differential input voltage capabilities. It serves as a foundational building block for voltage monitoring and threshold detection in complex electronic systems.
Replacement Considerations
LM2903B-Q1: Next-generation version with improved ESD and lower offset voltage. LM2903E-Q1: Extended temperature grade option reaching 150°C.
