Overview
The LMC6772QMM/NOPB is a dual micro-power rail-to-rail input CMOS comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 15 V and features an open-drain output configuration. The device is housed in an 8-pin VSSOP package and supports an operating temperature range from -40°C to +125°C. Designed for automotive applications, it meets AEC-Q100 qualification standards while maintaining low power consumption.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification
- Rail-to-rail input capability for maximum dynamic range
- Ultra-low quiescent current for battery-powered systems
- Open-drain output interface for flexible logic compatibility
Applications
- Automotive sensor signal conditioning
- Battery management system threshold detection
- Industrial control circuit monitoring
- Low-power portable electronic devices
Procurement Notes
Verify the specific suffix 'QMM' confirms the automotive grade and VSSOP-8 package variant. Confirm RoHS compliance status as indicated in official documentation. Ensure the NOPB designation matches the lead-free requirement for your assembly process. Cross-reference the manufacturer part number against the latest datasheet revision to confirm active status and any potential obsolescence notices.
Selection Notes
Select this component when automotive qualification and wide temperature operation are required. The rail-to-rail input allows sensing signals near the supply rails. The open-drain output requires an external pull-up resistor. Compare input offset voltage specifications against other variants if precision is critical. Ensure the VSSOP-8 footprint fits the PCB layout constraints.
Part Context
This part belongs to the LMC6772 family of dual comparators. It shares functional similarities with the LMC6772AIM/NOPB but differs in automotive qualification and package type. The Q-series designation indicates compliance with automotive reliability standards. It serves as a low-power alternative to higher-speed comparators in cost-sensitive automotive designs.
Replacement Considerations
LMC6772AIM/NOPB offers similar electrical performance but lacks automotive qualification. LMC6772BIMX/NOPB provides a SOIC-8 package option instead of VSSOP. Verify pinout compatibility before substitution. Check if the non-automotive variants meet the thermal requirements of the application.
