... Note: Other addresses are available. Contact SMSC for more information. 3.7 SMBus Timeout The EMC1046/EMC1047 support SMBus Timeout. If the clock line is held low for longer than 30ms, the device will reset its SMBus protocol. This function can be enabled by setting the TIMEOUT bit in the Consecutive Alert Register (see SMSC EMC1046/EMC1047 Table 3 ...

... Thermal management is performed in cooperation with a host device. This consists of the host reading the temperature data of both the external and internal temperature diodes of the EMC1046/EMC1047 and using that data to control the speed of one or more fans. Because the EMC1046/EMC1047 automatically corrects for temperature errors due to series ...

... External Diode channels to determine which of these channels is reporting the hottest temperature. The hottest temperature is stored in the Hottest Temperature Registers and the appropriate status bit in the Hottest Status Register is set optional feature, the EMC1046/EMC1047 can also flag an event if the hottest temperature channel changes. For example, suppose that External Diode channels 1, 3, and 4 are programmed to be compared in the “ ...

... Diode Connections The diode connection for the External Diode 1 channel is determined based on the selected device. For the EMC1046, this channel can support a diode-connected transistor (such as a 2N3904 substrate transistor (such as those found in an CPU or GPU) as shown in diodes are not supported on the External Diode 1 channel. ...

... CPU substrate PNP 4.3.1 Diode Faults The EMC1046/EMC1047 actively detects an open and short condition on each measurement channel. When a diode fault is detected, the temperature data MSByte is forced to a value of 80h and the FAULT bit is set in the Status Register. When an external diode channel is configured to operate in APD mode, the circuitry will detect independent open fault conditions, however a short condition will be shared between the APD channels ...
