SMSC EMCT03

DATASHEET

A conversion for all 3 temperature readings takes about 60ms. Therefore, the maximum conversion

rate, equals 16 conversions per second.

Bits 6 set of the Configuration Register sets the power mode of the part:

In Run Mode, the EMCT03 will operate at the preset conversion rate. In Standby Mode, the part is

powered down to minimize current consumption. The SMBus is fully operational in either mode. In

Standby Mode, a WRITE command to the One Shot register will trigger a one time conversion of the

3 temperature monitors. After the part finishes the conversion, it will go back to Standby Mode. The

host can now read the updated temperature information.
