Alarms occur when voltage measurements exceed an upper or lower threshold. Thermal management software uses temperature monitoring to control system cooling. The temperature channels have an optional hysteresis function that uses a lower threshold value to indicate when an alarm is deasserted to simplify the control of cooling strategies.
IMPORTANT: The over temperature (OT) limits and associated alarm are typically set at or close to the maximum recommended operating temperature of the device. The OT alarm is generally used to trigger an immediate but controlled shutdown of the equipment before erroneous operation or permanent damage occurs.
