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 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
