    EMC1002/EMC1033/EMC1402 EVB User Manual 1 Overview The EMC1002/1402 is an SMBus temperature sensing IC with 1 internal and 1 external sensor in an 8 pin MSOP package. The EMC1002/1402 has 2 outputs that can be Alert/Therm2 Addr/Therm configured to signal when temperatures exceed programmed limits. Resistance Error Correction can eliminate the affect of series resistance to provide a more accurate temperature reading.
  • Page 3: Getting Started

    USB driver installation. Follow the instructions in the readme.txt file to complete the installation process. 3. Start the EVB Software by selecting the Register Manager application from the SMSC folder from the Programs Windows Start menu. The EVB will initialize and the Register Manager Help screen...
  • Page 4 Note: The Windows Register Manager application allows viewing and changing register values for a variety of EVBs including the EMC1001, EMC1002, EMC1023 and 1033. The Register Manager software only needs to be installed once to support all of these EVBs. The list of supported EVBs may be found in the readme.txt file included on the distribution CD.

    5V fan to 3 different speeds based on programmable temperature limits. EMC1002/1033/1402 The EMC1002/1402 are SMBus temperature sensors with 1 internal and 1 external sensor in an 8 pin MSOP package. The EMC1033 has the same features plus support for a second external sensor in parallel with Remote 1 using the “Anti-Parallel Diode”...

    EMC1002/EMC1033/EMC1402 EVB User Manual Direct SMBus Connect Option It is also possible to connect an external SMBus master to the EMC1002 EVB. A few modifications to the circuit are required: Cut 3 traces connecting JP4 pins 3-4, 5-6 and 7-8 on the bottom side of the PCB. This will disconnect the USB bridge from the SMBus.
  • Page 7: Demo Description

    Temperature Limits and Alert/Therm2, Addr/Therm Outputs The high and low limits are displayed as dashed lines, initially with values set in the EMC1002.ini file. (or EMC1033.ini) These limits may be changed either in the register manager or by dragging the line on the history plot.
  • Page 8: Fan Driver

    RED on the Register Manager panel. Press the Response button to cause RegMan to send the SMBus Alert Address to the EMC1002/1033/1402 . The EMC1002/1033/1402 will respond with it’s SMBus address which is displayed in a text box next to the Response button on the RegMan interface.
