NCV8460
Self Protected High Side
Driver with Temperature
Shutdown and Current Limit
The NCV8460 is a fully protected High−Side driver that can be used
to switch a wide variety of loads, such as bulbs, solenoids and other
acuators. The device is internally protected from an overload
condition by an active current limit and thermal shutdown.
A diagnostic output reports ON and OFF state open load conditions
as well as thermal shutdown.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Not subjected to production testing
2. Reverse Output current has to be limited by the load to stay within absolute maximum ratings and thermal performance.
