Features (Typical unless otherwise noted) • Low power consumption (max):  IS = 10 μA/comp • Wide range of supply voltages: 2.7V to 15V • Rail-to-Rail input common mode voltage range • Open drain output • Short circuit protection: 40 mA • Propagation delay (@VS = 5V, 100 mV overdrive): 5 μs • LMC6772Q is AEC-Q qualified • LMC6772Q has −40°C to 125°C temperature range Description The LMC6772 is an ultra low power dual comparator with a maximum 10 μA/comparator power supply current. It is designed to operate over a wide range of supply voltages, with a minimum supply voltage of 2.7V. The common mode voltage range of the LMC6772 exceeds both the positive and negative supply rails, a significant advantage in single supply applications. The open drain output of the LMC6772 allows for wired-OR configurations. The open drain output also offers the advantage of allowing the output to be pulled to any voltage rail up to 15V, regardless of the supply voltage of the LMC6772. The LMC6772 is targeted for systems where low power consumption is the critical parameter. Guaranteed operation at supply voltages of 2.7V and rail-to-rail performance makes this comparator ideal for battery-powered applications. Refer to the LMC6762 datasheet for a push-pull output stage version of this device. Applications • Laptop computers • Mobile phones • Metering systems • Hand-held electronics • RC timers • Alarm and monitoring circuits • Window comparators, multivibrators

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
