FS26

Click image to open expanded view

The FS26 family of automotive safety system basis chips (SBCs) provides power management, system control, and diagnostic functions for automotive applications, including electrification, powertrain, chassis, safety, gateway, and S32K3-based systems.

The FS26 integrates multiple switch-mode and LDO regulators to supply microcontrollers, sensors, peripheral devices, and communication interfaces. It also includes a high-precision voltage reference, voltage-tracking regulators, GPIOs, an analog multiplexer, selectable wake-up sources, and SPI communication support.

The FS26 is compliant with ISO 26262 and supports safety applications up to ASIL B and ASIL D through fail-safe outputs and on-demand latent fault monitoring.

Note: Any FS26 OTP configuration where VBST is in front-end mode can also be used without it. Connect VBST_FB pin to the VSUP/VSUP_PWR node and follow our recommendations for the other unused pins in section '8. Connection of unused pins' from the FS26 Product datasheet.

Note: Any FS26 OTP configuration where VMONEXT pin is enabled and assigned to the ABIST1 can also be used without it. Connect an external resistor bridge divider to apply 0.8 V at VMONEXT pin.

Note: Each SFS26 part number corresponds to a unique OTP configuration, which is detailed in the FS26 product datasheet in terms of parameters and functionality.
