watchdog and reset functions dedicated for microprocessor
applications. Its robustness allows NCV8668 to be used in severe
automotive environments. Very low quiescent current as low as 38 m A
typical makes it suitable for applications permanently connected to
battery requiring very low quiescent current with or without load. The
Enable function can be used for further decrease of quiescent current
down to 1 m A.
The NCV8668 contains protection functions as current limit and
