Overview
The BA2903YF-MGE2 is a dual-channel standard open-collector comparator manufactured by Rohm Semiconductor, designed for automotive applications. It operates on a single supply voltage ranging from 2V to 36V or a dual supply of ±1V to ±18V. The device features a typical supply current of 0.6mA and an output current capability of 16mA. Key electrical specifications include a maximum input offset voltage of 7mV at 5V, a maximum input bias current of 0.25µA at 5V, and a typical response time of 1.3µs. It is housed in an 8-SOP package with dimensions of 5.0x6.2mm and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Supports direct ground sensing with common-mode input voltage range including ground level
- Includes internal electrostatic protection circuit with high human body model tolerance
- Qualified for automotive functional safety analysis under AEC-Q100 standards
Applications
- Engine control units
- Electric power steering systems
- Antilock brake systems
Procurement Notes
Verify the specific suffix MGE2 against official Rohm documentation to confirm pinout compatibility and RoHS status. Confirm that the component is marked as Not Recommended for New Designs (NRND) and assess long-term availability risks before finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring wide supply voltage operation and ground-level input sensing capabilities. Ensure the design accommodates the open-collector output configuration and verify that the 1.3µs response time meets the system's timing requirements.
Part Context
This part belongs to the BA2903 series of analog comparators developed specifically for automotive environments. It integrates two independent high-gain voltage comparators into a compact surface-mount package, providing a robust solution for signal comparison tasks in harsh operating conditions.
Replacement Considerations
LM2903EYFJ-CE2 is identified as a manufacturer-recommended substitute part number.
