NSI22C11 is a high-speed isolated comparator with output separated from input based on the NOVOSENSE capacitive isolation technology Adaptive OOK®. The NSI22C11 is an isolated single-ended comparator with both open-drain and push-pull output. The short response time of NSI22C11 makes it highly suitable for over-voltage protection application. The high common-mode transient immunity ensures that the device is able to provide accurate protection even in the presence of high-power switching such as in motor control applications. NSI22C11 have an adjustable input reference threshold from 0.5V to 2V. The reference can be set by an external voltage source or the 100μA internal current source flowing through an external resistor. The fail-safe function (missing VDD1 detection) simplifies system-level design and diagnostics.
