Failure of the system regulator IC leads to malfunction of electronic devices. The system particularly loses functionality when microcontroller (MCU) failure impacts on operation. “TB9042FTG” provides an SPI communication function to avoid this dangerous condition. The system regulator IC and the MCU identify trouble at the time of the abnormality by using the SPI communication function to monitor each other. Using the derived information, the system can carry out safe and timely processing.

Key Features

  • Two DCDC converters and three series regulators are built in
  • Various monitoring functions
    • Continuous monitoring of the system regulators.
      (High output voltage, Low output voltage, Overcurrent, Overheat, Unusual frequency)
    • Continuous monitoring of the MCU
      (Watchdog Timer, MCU alarm, MCU calculation function, Communication error)
    • Self-diagnosis function
      (High output voltage, Low output voltage, Output logic of each detection circuit)
  • SPI communication[1] reports the monitoring state to external system
  • When an unusual condition occurs, the output terminal immediately reports the monitored state to the external system. (Reset timer (RSTA/B), unusual voltage detection (NOVDET), MCU alarm (NOALM), All diagnosis result report (NDIAG)
