Overview
The BA2901YF-CE2 is a general-purpose analog comparator manufactured by ROHM Semiconductor, housed in a SOP-14 surface-mount package. It features four independent channels with open-collector outputs and differential inputs. The device operates within a supply voltage range of 2 V to 36 V and draws a typical operating current of 800 uA. Key electrical specifications include a response time of 1.3 us, an input offset voltage of 2 mV, and an input bias current of 50 nA. Each channel provides an output current capability of 16 mA. The component is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range from -40 C to +125 C.
Feature Summary
- Four-channel configuration providing independent comparison capabilities within a single integrated circuit.
- Ground-sense input functionality allowing operation near the negative supply rail.
- Automotive-grade qualification ensuring reliability in demanding environmental conditions.
- Open-collector output structure facilitating flexible interfacing with various logic families.
Applications
- Automotive ground sensing circuits
- Voltage level detection systems
- Threshold monitoring applications
Procurement Notes
Verify the specific suffix CE2 against the official ROHM datasheet to confirm pinout and packaging details. Confirm AEC-Q100 compliance requirements match the target application's automotive grade specifications. Check for any obsolescence notices or recommended replacement parts due to the NRND status associated with similar family members. Ensure the SOP-14 footprint matches the design layout constraints.
Selection Notes
Select this component when a quad-channel comparator with low power consumption and wide supply voltage tolerance is required. The open-collector output necessitates external pull-up resistors, which must be accounted for in the circuit design. Consider the 1.3 us response time for signal integrity in high-speed switching applications. Verify that the 2 mV input offset voltage meets the precision requirements of the sensing task.
Part Context
This part belongs to the BA2901 series of ground-sense comparators from ROHM Semiconductor. It shares functional similarities with other members like the BA82901YF-CE2 but may differ in specific electrical parameters or packaging variants. The series is designed for robust performance in industrial and automotive environments, emphasizing stability and wide operating ranges.
Replacement Considerations
