NSI22C12-Q1 is a high-speed isolated comparator with output separated from input based on the NOVOSENSE capacitive isolation technology Adaptive OOK?. The NSI22C12-Q1 is an isolated window comparator with open-drain output and latch enable function. The short response time of NSI22C12-Q1 makes it highly suitable for over-current 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. NSI22C12-Q1 have an adjustable input reference threshold of 20mV~ 320mV and the window threshold is from ±20mV to ±320mV. 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. The NSI22C12-Q1 supports reinforced isolation with SOW8 wide body package.
