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.

NCV8461
REVERSE BATTERY PROTECTION
The NCV8461 provides reverse battery protection up to
32 V. This protection requires a Resistor in the GND path.
The recommended GND resistor is 150 W, but a variety of
resistor values can be chosen for this purpose. The graph
below shows the considerations and constraints for selection
of the GND resistor. Figure 2 shows the power dissipation
in the GND resistor during a 32 V reverse battery event on
the left axis, while the right axis shows the voltage drop
across the GND resistor while in normal operation. The far
right side of the graph is grayed out to indicate that the
voltage drop across the resistor is too high, and the part will
not be able to turn on with a standard 5 V on the input pin.
Selection of the optimal GND resistor requires balancing the
power dissipation considerations while in a reverse battery
event, with the turn on capability of the input signal during
normal operation.
