BA2901YF-LBH2

Overview

The BA2901YF-LBH2 is a quad ground-sense analog comparator manufactured by ROHM Semiconductor. It operates within a supply voltage range of 2V to 36V, supporting both single and split power configurations. The device features four independent channels with open-collector outputs capable of sourcing up to 16mA. Key electrical characteristics include a typical response time of 1.3µs, a maximum input offset voltage of 7mV, and a typical input bias current of 50nA. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Ground-sense capability allowing common-mode input voltage range to include the negative rail (VEE).
• Standard comparator pin-assignments for simplified integration into existing designs.
• Internal ESD protection circuitry integrated on all input and output pins.

Applications

• Industrial equipment requiring long-term component support.
• Automotive systems utilizing AEC-Q100 qualified components.
• General-purpose signal comparison in wide-voltage environments.

Procurement Notes

Verify the NRND status carefully before procurement, as this designation indicates the component is not recommended for new designs. Confirm that the SOP14 package and taping specifications match your manufacturing requirements. Ensure compatibility with existing legacy systems, as replacement strategies may be necessary for future production phases due to end-of-life planning.

Selection Notes

Select this component when ground-referenced input sensing is required without level shifting. The wide supply voltage range accommodates various industrial power standards. Consider the open-collector output structure for flexible interfacing with different logic families. Verify thermal management needs given the operating temperature limits and package size constraints.

Part Context

This part belongs to the BA2901 series of ground-sense comparators designed for robust performance in harsh environments. The suffix LB(H2) typically denotes specific packaging or environmental compliance variations within the product line. It shares functional similarities with other members like the BA82901YF-CE2 but differs in automotive qualification and specific electrical tolerances defined by the manufacturer.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, direct replacements should be evaluated based on pin compatibility and electrical parameter equivalence rather than official substitution lists.
