EVB-EMC1002/EMC1033 User Manual

1 Overview

The EMC1002 is an SMBus temperature sensing IC with 1 internal and 1 external sensor in an 8 pin MSOP package. The EMC1002 has 2 Alert/Therm2 and Addr/Therm outputs that can be 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. This is especially important for microprocessors, FPGAs, and graphics chips. The EMC1033 is also supported by this evaluation board (EVB). The EMC1033 has an additional feature, “Anti-Parallel Diode” (APD) support which allows the connection of two diodes to the EMC1033’s DP/DN inputs in opposite polarity.

The EVB-EMC1002 and EVB-EMC1033 are USB-based platforms for evaluating the EMC1002/1033. A block diagram of the EVB is shown in Figure 1.1 below.
