Overview
The LM2903EYFVM-CTR is a dual-channel analog comparator from ROHM Semiconductor’s EMARMOUR™ series, designed for automotive applications. It operates on a single supply voltage ranging from 3V to 36V or split supplies of ±1.5V to ±18V. The device features low power consumption with a typical operating current of 600µA and an input bias current of 50nA. It offers high voltage gain of 120dB and a typical response time of 1.3µs. The output supports open-collector configuration with rail-to-rail capability and can source up to 16mA. It functions within an extended temperature range of -40°C to +150°C.
Feature Summary
- High EMI immunity performance suitable for automotive environments
- Wide operating supply voltage range supporting diverse system requirements
- Low power consumption optimized for engine control units and safety systems
- Open-collector output compatible with various logic families
Applications
- Engine Control Units (ECU)
- Electric Power Steering (EPS) systems
- Anti-lock Braking Systems (ABS)
Procurement Notes
Verify the specific suffix against official ROHM documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 automotive qualification standards required for your target application. Confirm RoHS compliance status directly with the manufacturer's latest datasheet before finalizing procurement orders.
Selection Notes
Select this component when high electromagnetic interference resistance is critical for signal integrity in noisy automotive environments. The wide supply voltage range allows flexibility in power design without level shifting. Consider the open-collector output structure for interfacing with different logic voltage levels in complex vehicle electronic architectures.
Part Context
This part belongs to the LM2903 family of dual comparators. The EYFVM variant specifically denotes the MSOP-8 package and automotive-grade reliability. It is distinct from standard industrial versions by its enhanced EMI protection features and extended temperature rating, aligning with modern vehicle electrification trends.
Replacement Considerations
Direct substitutes include other automotive-grade dual comparators with similar pinouts and electrical characteristics. Verify that any replacement maintains the same EMARMOUR™ EMI immunity level and operates within the required -40°C to +150°C temperature range for seamless integration.
