F75383/F75384
6.5 Temperature Monitoring
6.5 Alert#
The F75383/F75384 monitors a local and a remote temperature sensor. Both can be measured from 0°C to 140.875°C.
The temperature format is as the following table:
Five events can trigger ALERT# to low:
(1). VT1(Local) temperature exceeds High Limit
(2). VT1(Local) temperature goes below Low Limit
(3). VT2(Remote) temperature exceeds High Limit
(4). VT2(Remote) temperature goes below Low Limit
(5). VT2(Remote) temperature is Open-circuit.
These five events are wired-NOR together. This means that when one of out-of-limit event occurs, the ALERT# output goes low if the
MASK control is disabled. ALERT# signal can be used as an IRQ-like interrupt or as an SMBALERT. When ALERT# acts as an
IRQ-like interrupt, the ALERT# will be de-asserted until the following 2 conditions are matched:
(1). The abnormal condition is gone
