Overview
The BA2901YFV-MGE2 is a four-channel ground-sense comparator from ROHM Semiconductor, designed for automotive applications. It operates on a single supply of +2.0V to +36V or split supplies of ±1.0V to ±18V. Key electrical parameters include a typical response time of 1.3µs, voltage gain of 100dB, and output current of 16mA. The input offset voltage is typically 7mV maximum, with an input bias current of 50nA. It functions within a temperature range of -40°C to 125°C and is housed in a 14-SSOP-B package.
Feature Summary
- Supports wide operating supply voltage ranges for flexible power configurations
- Features standard comparator pin assignments for easy integration
- Includes internal ESD protection circuits for enhanced reliability
- Capable of supporting functional safety analysis for automotive use

Procurement Notes
This component is designated as not recommended for new designs. It is produced solely to support existing customers. Verify availability through authorized distributors, as stock levels may vary. Ensure the ordering suffix matches the required package type. Confirm RoHS compliance and automotive grade status before procurement.
Selection Notes
Select this part for legacy automotive designs requiring ground-sense comparators with wide supply voltage capabilities. It serves as a direct replacement for earlier BA2901 variants in SSOP-B packages. Consider the LM2901EYFV-CE2 for new designs due to its active status. Evaluate thermal performance within the specified -40°C to 125°C range for your application environment.
Part Context
The BA2901 series belongs to ROHM's EMARMOUR lineup, characterized by high EMI immunity for automotive environments. This specific variant uses the SSOP-B14 package, offering a compact footprint suitable for space-constrained PCB layouts. It adheres to AEC-Q100 standards, ensuring reliability under automotive stress conditions.
Replacement Considerations
The LM2901EYFV-CE2 is a manufacturer-recommended alternative for new designs. Both parts share similar electrical characteristics and channel counts. Verify pin compatibility and package dimensions when substituting. The LM2901 variant is actively supported for new projects.
FAQ
Is the BA2901YFV-MGE2 suitable for new design implementations?
No, it is explicitly marked as not recommended for new designs and is produced only for existing customer support.
What is the common-mode input voltage range?
The input voltage range extends from VEE to VCC-1.5V, allowing operation down to ground level.
