Overview
The BA82903YFVM-CTR is a dual-channel analog comparator from ROHM Semiconductor, designed for automotive applications. It features an open-collector output and operates within a supply voltage range of 2V to 36V. The device draws a typical circuit current of 0.6mA and provides a typical output current of 16mA. Key electrical specifications include a typical response time of 1.3µs, a maximum input offset voltage of 5mV, and a typical input bias current of 50nA. It is qualified under AEC-Q100 Grade 1 standards and functions across an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrated EMI filter providing high noise immunity suitable for automotive environments
- Ground-sense capability allowing input voltage range to extend down to VEE level
- AEC-Q100 Grade 1 qualification ensuring reliability in automotive systems
Applications
- Engine control units
- Electric power steering (EPS) systems
- Antilock brake systems (ABS)
Procurement Notes
Verify the specific suffix 'VM' corresponds to the MSOP-8 package variant when sourcing. Confirm that the 'CTR' designation indicates tape-and-reel packaging with the specified quantity. Ensure compatibility with existing board layouts requiring this specific footprint and pinout configuration for replacement or new designs.
Selection Notes
Select this component for designs requiring robust electromagnetic interference resistance without external filtering components. It is suitable for low-power applications due to its low supply current consumption. The wide common-mode input range simplifies interface design for ground-referenced signals in automotive circuits.
Part Context
This part belongs to ROHM's EMARMOUR™ series, which utilizes specialized circuit design and layout techniques to achieve superior anti-noise performance. The BA82903YFVM-CTR integrates two independent high-gain comparators on a single chip, offering a compact solution for complex sensing requirements in vehicle electronics.
Replacement Considerations
Direct substitutes may include other ROHM automotive comparers with similar pinouts and electrical characteristics, such as the LM2903EYFVM-C series, provided functional safety and EMI performance requirements are met.
