The smart fuse high-side switch portfolio (HCS device family) from Texas Instruments (TI) 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 communication to configure various parameters such as capacitive charging and I2T, and to read out diagnostics such as current sense (through an integrated ADC) and fault detection. To simplify software development, TI provides a full suite of software drivers and code examples across multiple processor or microcontroller platforms (both from TI and otherwise). This application note describes all the aspects of the smart fuse software ecosystem from TI, 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.
