LMC6772QMMX/NOPB

Overview

The LMC6772QMMX/NOPB is an ultra-low power dual comparator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates over a supply voltage range of 2.7 V to 15 V and features a maximum power supply current of 10 μA. The device utilizes an open-drain output configuration and is housed in an 8-VSSOP package. It supports single or split supply operation, making it suitable for low-power sensing and signal conditioning tasks in harsh environments.

Feature Summary

• Ultra-low power consumption with maximum 10 μA supply current
• Automotive grade reliability with AEC-Q100 qualification
• Wide single-supply operating voltage range from 2.7 V to 15 V
• Open-drain output structure for flexible interfacing

Applications

• Automotive sensor signal conditioning
• Low-power battery monitoring systems
• Industrial control logic interfaces
• Temperature threshold detection circuits

Procurement Notes

Verify the specific suffix 'QMMX' confirms the automotive qualification (AEC-Q100) and tape-and-reel packaging format. Ensure the design accounts for the open-drain output requirement, which necessitates an external pull-up resistor for proper logic high levels. Confirm that the 8-VSSOP package dimensions match the target PCB footprint constraints.

Selection Notes

Select this component when minimizing quiescent current is critical, such as in battery-operated automotive modules. The wide input common-mode range and low supply voltage capability make it suitable for direct interface with various sensors. Consider the open-drain output if level shifting or wired-OR configurations are required in the system architecture.

Part Context

This part belongs to the LMC6772 family of dual comparators. The 'Q' prefix indicates automotive qualification, while 'MMX' specifies the VSSOP-8 package and reel packaging. It serves as a low-power alternative to standard comparators in applications where energy efficiency and automotive durability are primary design constraints.

Replacement Considerations

Direct replacements must maintain AEC-Q100 qualification and similar pinout compatibility. Verify that substitute parts support the 2.7 V minimum supply voltage and offer comparable propagation delay characteristics. Ensure the replacement also features an open-drain output if the existing circuit design relies on this topology.
