Overview
The BA2901YF-MGE2 is a four-channel analog comparator manufactured by Rohm Semiconductor, designed for automotive applications with AEC-Q100 qualification. It operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. Key electrical specifications include a typical circuit current of 0.8mA, maximum input offset voltage of 7mV, and typical input bias current of 50nA. The device features an open-collector output capable of sourcing 16mA, with a typical response time of 1.3µs and voltage gain of 100dB. It functions within an operating temperature range of -40°C to 125°C and is housed in a 14-SOP package.
Feature Summary
- Operates with wide single or dual power supply voltages
- Includes internal ESD protection circuits
- Supports ground sense input operation
- Complies with AEC-Q100 automotive standards
Applications
- Automotive functional safety analysis support
- Industrial application monitoring
- General-purpose signal comparison
Procurement Notes
This component is designated as not recommended for new designs and is produced solely to support existing customers. Verify current availability status directly with the manufacturer before procurement planning. Ensure that design updates consider the non-recommended status for long-term project viability.
Selection Notes
Select this part only if maintaining compatibility with legacy automotive systems requiring AEC-Q100 grade comparators. Evaluate the trade-off between the established supply chain for existing clients versus the recommendation to adopt newer alternatives for future development cycles.
Part Context
The BA2901YF-MGE2 belongs to the BA2901 series of ground-sense comparators. It shares core specifications with variants like the BA2901YF-LB(H2) but differs in packaging and specific automotive qualification suffixes. It serves as a specialized component for robust industrial and automotive environments requiring high reliability.
Replacement Considerations
The LM2901EYFV-CE2 is identified as a manufacturer-recommended substitute. This alternative offers similar channel counts and automotive qualifications but may differ in package type (SSOP-B-14 vs SOP-14) and specific electrical characteristics such as input offset voltage.
