Overview
The LM8391EYG-CTR is a high-gain, ground-sense input comparator from the EMARMOUR™ series, designed for automotive applications. It operates on a wide supply voltage range of 3V to 36V with typical supply current of 0.3mA. Key electrical parameters include a maximum input offset voltage of 5mV, typical input bias current of 50nA, and typical response time of 1.3µs. The device features a voltage gain of 120dB and output current of 16mA. It supports single or dual power supplies, operates from VEE to VCC-1.5, and functions within a temperature range of -40°C to 150°C in an SSOP5 package.
Feature Summary
- EMARMOUR™ Series with excellent EMI immunity performance
- Operable from almost GND level for input
- AEC-Q100 Qualified (Grade 1)
- Low supply current
Applications
- Engine control units
- Electric Power Steering (EPS)
- Anti-lock Braking Systems (ABS)
Procurement Notes
Verify the specific suffix 'CTR' indicates tape and reel packaging configuration as per official documentation. Confirm AEC-Q100 Grade 1 qualification status matches project requirements. Ensure the SSOP5 package dimensions align with PCB layout constraints. Check functional safety classification details if system-level safety analysis is required.
Selection Notes
Select this component when high EMI immunity is critical for automotive signal integrity. The ground-sense input capability allows detection near zero volts, suitable for low-side sensing applications. The wide operating temperature range up to 150°C supports harsh engine bay environments. Compare against standard comparers if EMI resistance is a primary design constraint.
Part Context
This part belongs to ROHM's EMARMOUR™ series, which focuses on enhancing electromagnetic interference resistance for automotive electronics. It shares the same core comparator architecture as the LM8391EZG-C but includes specific enhancements for EMI robustness. Both variants utilize the SSOP5 package and target similar automotive control systems.
Replacement Considerations
LM8391EZG-C is a comparable variant within the same family offering similar electrical characteristics without the specific EMARMOUR™ EMI enhancements.
