Overview
The LM2901EYFV-CE2 is a four-channel analog comparator from ROHM Semiconductor's EMARMOUR series, designed for automotive applications. It features an SSOP-B14 package with open collector outputs and operates on a single or dual supply voltage ranging from 3 V to 36 V. The device draws a typical supply current of 1.2 mA per channel and offers a response time of 1.3 µs. It supports input voltages from VEE to VCC-1.5 V, ensuring ground-sense capability. The component is qualified under AEC-Q100 Grade 1 standards and functions within a temperature range of -40 °C to +150 °C.
Feature Summary
- High electromagnetic interference immunity characteristic suitable for automotive environments
- Ground-sense input capability allowing operation near the negative rail
- AEC-Q100 Grade 1 qualification for automotive reliability
- Wide operating temperature range extending up to 150 °C
Applications
- Engine control units
- Electric power steering systems
- Anti-lock braking systems
Procurement Notes
Verify the specific suffix CE2 against the manufacturer's datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SSOP-B14 package dimensions are compatible with the PCB footprint. Confirm that the open-collector output configuration aligns with the downstream logic interface. Check for any functional safety support documentation if required by the application standard.
Selection Notes
Select this component when high EMI immunity and ground-sense inputs are critical for automotive signal processing. The wide supply voltage range accommodates various automotive bus architectures. Consider the thermal performance in the SSOP-B14 package for high-temperature environments. Verify that the 1.2 mA quiescent current meets system power budget constraints compared to lower-power alternatives.
Part Context
This part belongs to the LM2901 family of ground-sense comparators. It is the automotive-grade version of the LM2901, distinguished by its enhanced EMI resistance and extended temperature rating. It serves as a specialized replacement for general-purpose comparators in harsh electromagnetic environments found in modern vehicles.
Replacement Considerations
LM2901EYFV-C is listed as an alias for this component.
