6.4 Temperature Monitoring
6.5 Alert#
entry key writing, the address will keep default value 98h. For example, use 30k resistor for address 6A selection. User need to
write entry key to register CRFAh.
The F75393 monitors a local and a remote temperature sensor. Both can be measured from -40°C to 127.875°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.
