Overview
The LMC7215QIM5X/NOPB is an automotive-grade, micro-power, rail-to-rail CMOS analog comparator manufactured by Texas Instruments. It features a push-pull output stage and operates on a single supply voltage ranging from 2 V to 8 V. Key electrical specifications include a maximum input offset voltage of 6 mV at 5 V, a typical operating supply current of 1 µA, and a propagation delay of approximately 10 µs. The device is housed in a compact SOT-23-5 package and is rated for operation over an extended industrial temperature range.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability in vehicle applications.
- Micro-power consumption design utilizing CMOS technology to minimize energy usage in battery-operated systems.
- Rail-to-rail input capability allows signal processing near the supply voltage rails without performance degradation.
Applications
- Battery-powered consumer electronics requiring low quiescent current.
- Automotive sensing circuits and monitoring systems.
- Threshold detection in portable medical devices.
Procurement Notes
Verify that the specific suffix Q indicates automotive grade qualification when sourcing. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Ensure the supplier provides traceability documentation suitable for automotive manufacturing processes. Check for RoHS compliance status as indicated in official datasheets.
Selection Notes
Select this component when automotive reliability is required alongside ultra-low power constraints. Compare against standard LMC7215 variants if automotive certification is unnecessary. Consider the push-pull output drive capability versus open-drain options based on interface requirements. Evaluate the 1 µA supply current against system power budgets.
Part Context
This part belongs to the LMC7215 family of micro-power comparators. The 'Q' prefix denotes automotive qualification, distinguishing it from commercial grades like the LMC7215IM5X/NOPB. It shares functional similarities with other rail-to-rail comparators but offers specific automotive durability and testing protocols defined by Texas Instruments.
Replacement Considerations
Direct substitutes include the LMC7215IM5X/NOPB for non-automotive applications. For automotive needs, verify pin compatibility with other TI automotive comparers. Cross-reference with LMV721 series if higher speed is acceptable, noting significant differences in power and bandwidth specifications.
