Product Details

Top Features

  • Control and diagnostic reporting through a serial peripheral interface (SPI) 
  • Wide input voltage range (6 to 36 VIN operating range, 40 VIN maximum)
  • 2.2 MHz Synchronous buck 5.35V pre-regulator (VREG) for integration and efficiency
  • Five internal linear regulators with foldback short-circuit protection 
    • 3.3V and 4x 5V outputs (one with short- to-battery protection for remote sensors)
  • OV and UV protection for all output rails provide the ability to monitor health of outputs
  • Pin-to-pin and pin-to-ground tolerant at every pin
  • Three configurable watchdogs with fail-safe features: pulse period, window, Q&A watchdog
  • Power-on reset signal (NPOR) indicating a fault on the 3.3V output, the optional 1.3V input monitor (for self-powered core voltage) and a watchdog failure 
  • Safety signal (POE) can disable a separate function (e.g., Motor Driver) due to a Watchdog Failure
