Overview
The BA2903YFV-MGE2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, designed for automotive applications. It features an open-collector output type and operates within a supply voltage range of 2V to 36V on a single supply or ±1V to ±18V on a split supply. The device draws a maximum static current of 1mA and provides a typical output current of 16mA at 5V. Key electrical parameters include a maximum input offset voltage of 7mV at 5V and a maximum input bias current of 0.25µA at 5V. It is housed in an 8-SOP surface-mount package with a width of 4.40mm and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- AEC-Q100 qualified for automotive grade reliability
- Ground sense capability allowing common-mode input voltage range to include ground level
- Standard comparator pin-assignments for easy replacement
- Internal ESD protection circuit integrated
Applications
- Engine control units
- Electric power steering systems
- Antilock brake systems
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before finalizing any design implementation. Confirm that the specific ordering suffix matches the required package and tape/reel specifications. Ensure compatibility with existing automotive qualification standards if replacing legacy parts. Check for available manufacturer-recommended substitutes such as the LM2903EYFJ-CE2 if new production is required.
Selection Notes
Select this component when a dual-channel comparator with ground-sense inputs is required for automotive environments. The wide supply voltage range and low power consumption make it suitable for battery-powered vehicle systems. Verify that the 8-SOP package dimensions fit the target PCB layout constraints. Consider the open-collector output requirement for interfacing with downstream logic circuits.
Part Context
This part belongs to the BA2903 series of general-purpose comparators from ROHM Semiconductor. The series is specifically engineered to meet automotive requirements, offering high gain and low supply current. The BA2903YFV-MGE2 variant integrates two independent comparator circuits into a single chip, providing a compact solution for signal comparison tasks in harsh electromagnetic environments.
Replacement Considerations
The LM2903EYFJ-CE2 is listed as a manufacturer-recommended substitute. Verify pinout compatibility and electrical parameter equivalence before substitution.
