The MC34VR50020monitors the temperature, input voltage and output currents and provides21corresponding alarms. For the temperature, the chip can send interrupts if22the temperature rises above one of the following values: 110°, 120°, 125° and23130° Celsius. For the input voltage, an interrupt is sent when the voltage24drops below 2.8V.25 26Currently, this driver only implements the input voltage and temperature27alarms. The interrupts are mapped as follows:28 29<= 2.8V -> in0_min_alarm30>110°c -> temp1_max_alarm31>120°c -> temp1_crit_alarm32>130°c -> temp1_emergency_alarm33
