Overview
The LMV393QDRQ1 is a dual general-purpose analog comparator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector/open drain output type. Key electrical parameters include a maximum response time of 200 ns, a quiescent current of 140 uA, and an input offset voltage of 7 mV. The device supports a common-mode voltage down to -100 mV and delivers up to 23 mA per channel output current. It functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards for robust performance in vehicle environments.
- Low-voltage operation capability enabling efficient power management in battery-powered systems.
- Dual-channel architecture providing two independent comparison functions within a single compact package.
Applications
- Automotive sensor signal conditioning
- Battery monitoring circuits
- Temperature threshold detection
Procurement Notes
Verify the specific suffix QDRQ1 matches the required automotive grade and SOIC-8 packaging configuration. Confirm that the AEC-Q100 qualification aligns with your project's reliability requirements. Ensure the operating temperature range meets environmental specifications. Cross-reference datasheet revisions to guarantee compatibility with existing design constraints.
Selection Notes
Select this component when dual comparators are needed in low-voltage automotive designs. Consider the 200 ns response time for speed requirements. Evaluate the 140 uA quiescent current against power budget constraints. Verify that the open-drain output suits the pull-up resistor configuration in the target circuit.
Part Context
This part belongs to the LMV393 family of low-voltage comparators. The 'Q' indicates automotive qualification, while 'DRQ1' specifies the SOIC-8 tape-and-reel packaging variant. It serves as a specialized version of the standard LMV393, tailored for harsh automotive environments requiring extended temperature stability and high reliability.
Replacement Considerations
LMV393IDR is a non-automotive equivalent with similar electrical characteristics but lacks AEC-Q100 certification. LMV393IPWR offers the same functionality in a TSSOP-8 package instead of SOIC-8. Verify pinout compatibility and thermal performance before substitution.
