The smart fuse high-side switch portfolio (HCS device family)
from Texas Instruments provides a versatile and powerful set of
devices that allow for seamless replacement of physical melting fuse
devices with a configurable semiconductor design in automotive
applications. The HCS high-side switch device family uses SPI as it
means of communication to configure various parameters such as
capacitive charging/I2T as well as read out diagnostics such as
current sense (through an integrated ADC) and fault detection. To
simplify software development, Texas Instruments provides a full
suite of software drivers and code examples across multiple
processor or microcontroller platforms (both from Texas Instruments
and otherwise). This application note dives deep into all aspects of
the smart fuse software ecosystem from Texas Instruments including
the top level drivers, configuration or evaluation tool, and a full
set of code examples that show common use cases of the underlying
smart fuse devices.
