High-side switch controller with intelligent fuse protection for automotive applications


Automotive high-side switch controller combines enhanced system-protection and diagnostic features with ST’s I2-t silicon-fuse feature

Its flexibility is ideal for the latest automotive zonal electronic/electrical (E/E) architectures that boost efficiency and reliability while supporting increased electrification and extra functions for smart driving.

Key features

The feature-rich and adaptable VNF1048F has a serial peripheral interface (SPI) for a host microcontroller to configure and monitor system-protection and diagnostic features. These include under-voltage and over-temperature protection, thermal protection for the external high-side MOSFET, desaturation shutdown, and I2-t fuse settings. High-precision digital current sensing is built in. Analog-to-digital converters (ADCs) for monitoring the temperature-sensing thermistor voltage, output voltage, and MOSFET drain-source voltage are also integrated.
