Self-Protected Low Side
Driver with In-Rush Current
Management
NCV8412, NCV8412D
The NCV8412 is a three terminal protected Low−Side Smart
Discrete FET. The protection features include Delta Thermal
Shutdown, overcurrent, overtemperature, ESD and integrated
Drain−to−Gate clamping for overvoltage protection. The device also
offers fault indication via the gate pin. This device is suitable for harsh
automotive environments.

APPLICATION INFORMATION
Circuit Protection Features
junction temperature is exceeded. When activated at
typically 175°C, the NCV8412 turns off. This feature is
provided to prevent failures from accidental overheating.
The NCV8412 has three main protections. Current Limit,
Thermal Shutdown and Delta Thermal Shutdown. These
protections establish robustness of the NCV8412.
EMC Performance
Current Limit and Short Circuit Protection
The NCV8412 has current sense element. In the event that
the drain current reaches designed current limit level,
integrated Current Limit protection establishes its constant
level.
If better EMC performance is needed, connect a small
ceramic capacitor to the drain pin as close to the device as
possible according to Figure 23.
Delta Thermal Shutdown
Delta Thermal Shutdown (DTSD) Protection increases
higher reliability of the NCV8412. DTSD consist of two
independent temperature sensors – cold and hot sensors. The
NCV8412 establishes a slow junction temperature rise by
sensing the difference between the hot and cold sensors.
ON/OFF output cycling is designed with hysteresis that
results in a controlled saw tooth temperature profile
(Figure 24). The die temperature slowly rises (DTSD) until
the absolute temperature shutdown (TSD) is reached around
175°C.
Thermal Shutdown with Automatic Restart
Internal Thermal Shutdown (TSD) circuitry is provided to
protect the NCV8412 in the event that the maximum
