- Anti-lock braking systems (ABS)
Procurement Notes
Verify component authenticity through authorized Rohm Semiconductor distributors or certified partners. Confirm the specific suffix CE2 matches the required packaging configuration. Check for RoHS compliance documentation relevant to the manufacturing date code. Ensure the NRND status does not conflict with long-term production lifecycle requirements for the target application.
Selection Notes
Select this component when high electromagnetic interference resistance is critical for signal integrity in noisy automotive environments. The ground-sense input feature simplifies circuit design for low-side sensing applications. Consider the open-collector output type for flexible interfacing with various logic levels. Evaluate the 1.3 µs response time against system switching speed requirements.
Part Context
This part belongs to the BA82901Yxx-C series of ground-sense comparators designed specifically for automotive use. It integrates four independent high-gain comparators on a single chip to reduce board space. The series is characterized by low power consumption and wide operating voltage ranges, making it suitable for battery-powered and alternator-fed vehicle systems.
