2.3 Status LEDs and Sub-regulator

The green LED D2 illuminates when VDD is supplied. VDD must be supplied for normal operation of the TMP113EVM as VDD is used for device power and communication line pullup voltages. VDD can be supplied via the on-board sub-regulator U7 or external power. See Section 2.6 for more details.

The orange ALERT LED and red T_CRIT LED illuminate when the corresponding ALERT/THERM2 and THERM device pins are asserted (active-low). An overtemperature or undertemperature alarm on local and remote temperatures is triggered when measurements exceed user-programmed limits. Additional thermal limits can be programmed to trigger the THERM flag.

The green LED D6 is the MSP430F5528 status LED. Table 2-1 shows how the different modes of operation are displayed by the LED status.
