Two voltage monitor inputs on the EMC2300 monitor Vccp and 3.3V. The EVB has a potentiometer to
adjust the Vccp levels.
This demo board derives +5V power from the USB port. The bridge microcontroller has an internal
voltage regulator that supplies +3.3V to the EMC2300 and other EVB circuits including the zone
heaters. When driving +12V fans, an external +12V supply is required. +12Vdc may be supplied
through either Power Jack P5 or the screw terminal connector P6.
Note: A recommended +12V power supply is P/N: CUI-Stack DTS120420UTC-P5P-SZ.
The
line is also routed to the USB bridge to provide Alert status to the Demo application.
It is possible to communicate with the EMC2300 using an external SMBus master. To do so, the on-
board USB to SMBus bridge master must be disconnected. This is accomplished by removing the
jumpers connecting pins 1-2, 3-4, 5-6 and 7-8 on JP3. Once the bridge is disconnected, the SMBus
master may be connected via P1 or P11.
Note: +5V power must be applied to the EVB, either through the USB cable or the +5V test point.
Note: The pullup resistors for the SMBus SDA, SCL and
