... Chapter 3 Product Description The EMC1043 is an SMBus sensor that monitors three temperature zones for use in a personal computer or embedded environment. The part may be used as a companion to one of SMSC’s broad line of SIO host devices to perform fan control and thermal management. The EMC1043-1, EMC1043-2, EMC1043-3 and EMC1043-4 are designed specifically to work with a CPU that implements the thermal diode as a PNP substrate transistor with the collector connected to GND ...
