Safety System Basis Chip with Low Power, for ASIL D Systems

FS26 Active

Roll over image to zoom in

The FS26 family of automotive safety system basis chip (SBC) devices offer multiple power supply options designed to support entry and mid-range safety microcontrollers like the S32K3 series. FS26 devices also enable other microcontrollers targeting automotive electrification such as powertrain, chassis, safety and low-end gateway applications.

The FS26 features multiple switch mode regulators as well as LDO voltage regulators to supply the microcontroller, sensors, peripheral ICs and communication interface. FS26 offers a high-precision voltage reference available to the system and a reference voltage for 2 independent voltage-tracking regulators. In addition, various functionalities are available for system control and diagnostics such as analog multiplexer, GPIOS and selectable wake up events from I/O, long duration timer or SPI communication.

The FS26 is ISO 26262 compliant, covering ASIL B and ASIL D safety integrity levels. It features multiple fail-safe outputs, becoming a full part of a safety-oriented system partitioning, along with the latest 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.
