ONSEMI NCV8461-D

NCV8461
Self Protected High Side
Driver with Temperature
Shutdown and Current Limit
The NCV8461 is a fully protected High−Side driver that can be used
to switch a wide variety of loads, such as bulbs, solenoids and other
activators. The device is internally protected from an overload
condition by an active current limit and thermal shutdown. A
diagnostic output reports OFF state open load conditions as well as
thermal shutdown.
