Overview
The BA2903YF-CE2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 2 V to 36 V and consumes 600 uA of operating current. The device features an open collector output capable of sourcing 16 mA per channel, with a typical response time of 1.3 us. Input characteristics include a maximum offset voltage of 5 mV and a typical bias current of 50 nA. It functions in temperatures from -40°C to +125°C and is housed in an SOP-8 package.
Feature Summary
- Supports ground-sense operation allowing inputs and outputs to operate near ground potential.
- Includes built-in electrostatic protection circuits rated at ±5000 V (Typ.) under human body model conditions.
- Compatible with standard comparator terminal connections for simplified circuit integration.
Applications
- Automotive electronic systems requiring functional safety support analysis
- General-purpose signal comparison in low-voltage environments
- Industrial control circuits operating within wide temperature ranges
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before implementation. Confirm that the SOP-8 package and taping packaging align with existing assembly lines. Ensure compliance with RoHS directives and AEC-Q100 automotive grade requirements for target deployment environments.
Selection Notes
Select this component when dual-channel comparison with ground-sense capability is required in automotive or industrial settings. Consider the 2 V minimum supply voltage for low-power applications. Evaluate the 1.3 us response time against system speed requirements. Verify thermal management needs for the specified -40°C to +125°C operating range.
Part Context
This part belongs to the BA2903 series of standard open-collector comparators developed for automotive use. It supports functional safety analysis and is characterized for high reliability in harsh environments. The series emphasizes wide supply voltage tolerance and robust input protection mechanisms suitable for vehicle electronics.
Replacement Considerations
Check for pin-compatible alternatives within the same ROHM family if new design adoption is restricted. Verify electrical parameter equivalence for supply voltage, offset voltage, and output current capabilities before substitution.
