The MC34VR500 +monitors the temperature, input voltage and output currents and provides +corresponding alarms. For the temperature, the chip can send interrupts if +the temperature rises above one of the following values: 110°, 120°, 125° and +130° Celsius. For the input voltage, an interrupt is sent when the voltage +drops below 2.8V. + +Currently, this driver only implements the input voltage and temperature +alarms. The interrupts are mapped as follows: + +<= 2.8V -> in0_min_alarm +>110°c -> temp1_max_alarm +>120°c -> temp1_crit_alarm +>130°c -> temp1_emergency_alarm |
