Overview
The LMC6772QMMX/NOPB is a dual micropower rail-to-rail input CMOS comparator with open-drain outputs. It operates on supply voltages from 2.7V to 15V, drawing a maximum of 10µA per comparator. The device features an input common-mode voltage range that exceeds both supply rails and supports propagation delays as low as 4µs at 100mV overdrive. Qualified under AEC-Q100 standards, it functions reliably across a temperature range of -40°C to 125°C.
Feature Summary
- Rail-to-rail input common-mode voltage range exceeding supply rails
- Ultra-low power consumption suitable for battery-powered systems
- Open-drain output allowing wired-OR configurations and flexible pull-up voltages
- Short circuit protection up to 40mA
Applications
- Laptop computers
- Mobile phones
- Metering systems
- Hand-held electronics
- Alarm and monitoring circuits
Procurement Notes
Verify the specific suffix 'S7002298' against official Texas Instruments documentation, as standard ordering part numbers typically follow the format LMC6772QMMX/NOPB. Confirm package type VSSOP (DGK) and ensure compatibility with automotive-grade requirements if applicable. Cross-reference datasheet revision SNOS749F for accurate electrical characteristics.
Selection Notes
Select this component for applications requiring low quiescent current and wide supply voltage operation. The rail-to-rail input capability simplifies interfacing with sensors near ground or positive rails. Ensure output load currents remain within the 30mA limit to maintain reliability. Consider the open-drain architecture when designing logic level shifting or wired-OR bus structures.
Part Context
This device belongs to the LMC6772 family of dual comparators manufactured by Texas Instruments. It serves as the automotive-qualified variant (LMC6772Q) designed for high-reliability environments. The Q-series designation indicates compliance with AEC-Q100 standards, distinguishing it from standard commercial grades like the AIM or BIM variants.
Replacement Considerations
Direct substitutes include LMC6772AIMX/NOPB and LMC6772BIMX/NOPB for non-automotive applications. For automotive use, verify availability of other LMC6772Q variants such as LMC6772QMM/NOPB in different packaging options.
