AMICO 8 Channel Pre Diagnosis Device
  • active Active

The device has integrated several functions which save job load of the microcontroller and save necessary connections to the microcontroller. It’s possible to connect analog and digital high side drivers (HSD) to the device and control them via SPI interface. A synchronous detailed diagnostics feature is integrated.

The device has 8 outputs to the HSD with the possibility to be driven either by steady state ON/OFF mode or by PWM. Two clock inputs used as base frequency to generate the PWM signal internally are provided. The outputs are fully independent and can also be driven with phase shift to improve characteristics of power net during the inrush phase. The device has 8 current sense (CS)/status (ST) pins connected to the HSD to run diagnostics. The index of ST/CS pin corresponds to the input connected to the same HSD channel (ST0/CS0 with OUT0, ST1/CS1 with OUT1 ...).
