Overview
The BA82903YF-CE2 is a dual-channel analog comparator from ROHM Semiconductor, designed for automotive applications with AEC-Q100 qualification. It features an open collector output and operates within a supply voltage range of 2 V to 36 V. The device draws a typical operating current of 600 uA and provides an output current of 16 mA per channel. Key electrical parameters include a response time of 1.3 us, an input offset voltage of 2 mV, and an input 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
- Ground-sense input capability allowing operation near ground potential
- High EMI noise tolerance suitable for automotive environments
- Wide single-supply voltage operation range
Applications
- Engine control units
- Electric Power Steering (EPS) systems
- Anti-lock Braking Systems (ABS)
Procurement Notes
Verify the NRND status before integration, as this component is not recommended for new designs. Confirm that existing inventory or last-time buy options meet project timelines. Ensure compatibility with SOP-8 footprints during PCB layout finalization. Check for updated datasheets regarding any minor manufacturing changes while the part remains available for legacy support.
Selection Notes
Select this comparator when ground-referenced signal detection is required in noisy automotive circuits. The low power consumption and wide voltage range make it suitable for battery-powered or variable supply systems. Consider the open-collector output requirement for pull-up resistor implementation. Verify thermal performance within the specified industrial temperature range for long-term reliability.
Part Context
This component belongs to the BA8290x series of ground-sense comparators. It integrates two independent comparison circuits on a single chip. The series is engineered for robustness in high-noise automotive environments. It serves as a specialized solution for safety-critical vehicle electronics requiring reliable signal threshold detection.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Evaluate pin-compatible alternatives only if they match the specific ground-sense and EMI tolerance requirements. Verify that any replacement maintains the AEC-Q100 automotive grade certification.
