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.

Features

Power Management

  • 40 V DC maximum input voltage
  • Handle severe cranking operation (3.2 V battery) due to its BOOST controller
  • Low Power Off mode with very low sleep current (30 uA typ.)
  • Low Power Standby mode, VPRE active. LDO1 or LDO2 active selectable via OTP configuration (25 uA typ.)
  • Multiple switch mode regulators as well as LDO voltage regulators to supply the microcontroller, sensors, peripheral ICs and communication interface

System Solutions

  • System added value to save space and reduce complexity: LDT, AMUX, Dual Tracker, Vref
  • Programmable long duration timer (LDT) for system turn-off/wake-up control
  • Selectable wake-up sources from: WAKE/GPIO pins, LDT or SPI activity

Functional Safety

  • Scalable portfolio from automotive safety integrity levels ASIL B to ASIL D
  • Enable latent fault monitoring when system is running: ABIST on-demand
  • Independent monitoring circuitry
  • Dedicated interface for microcontroller monitoring
  • Simple and challenger watchdog function
  • Safety outputs with latent fault detection mechanism (RSTB, FS0B, FS1B)

Configuration and Enablement

  • LQFP48 pins with exposed pad for optimized thermal management
  • Permanent device customization via one-time-programming (OTP) fuse memory
  • Temporary OTP emulation mode for system development and evaluation
  • Ready to use S32K3 + FS26 hardware and software

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.
