Microchip Open Drain CMOS Comparator 5.5V 1.6V Supply Voltage 8-Pin SOIC MCP6547T-I/MS

Microchip MCP6547T-I/MS is an open drain CMOS comparator specifically engineered for low power and single-supply circuit designs requiring high precision and reliability. Operating with supply voltages as low as 1.6 V up to 5.5 V, it fits compact applications using surface mount technology in an 8-pin SOIC package with dimensions 2.25mm by 2.4mm by 1.1mm.

This sub microamp comparator draws only 600nA of quiescent current per comparator, making it highly suitable for battery-operated and power-sensitive industrial equipment. Its open-drain output stage can drive heavy DC and capacitive loads, and can also function as a level-shifter with external pull-up resistors for voltages up to 10 V.

The device operates across a robust temperature range from -40°C to +125°C, meeting industrial and extended automotive operating requirements, and passes AEC-Q100 automotive qualification for superior durability and quality assurance.

Rail-to-rail input capability ensures full input voltage range utilization, while a typical propagation delay of 4 µs with 100 mV overdrive allows for fast responsive performance in control systems and signal conditioning circuits.

Microchip MCP6547T-I/MS comparators find applications in industrial automation, instrumentation, electronic measurement devices, automotive sensor interfaces, and other precision analog circuit requirements.

The comparator offers sub microamp supply current with typical 600nA consumption per comparator. It supports wide operating temperatures from -40°C to 125°C for industrial and extended range applications.
