2.1.2 Power Control [SW1] with LED for Status [LD7][LD8][LD9]

The EVM supports a manual switch [SW1] for power control to the EVM. The switch [SW1] is a two-position switch. The OFF position disconnects input power from on-board circuitry. The ON position connects the input power.

Three status LEDs [LD7][LD8][LD9] are used to communicated power status to the user.

Table 2-2 Power Domain Status
LED ‘ON’ State ‘OFF’ State
[LD7] Power switch [SW1] is in the ON position, and input power is being supplied to the EVM. Power switch [SW1] is in the OFF or there is some other issue causing power to not be supplied.
[LD8] MCU domain of the EVM is powered MCU domain of the EVM is not powered/OFF (1)
[LD9] MAIN domain of the EVM is powered MAIN domain of the EVM is not powered/OFF (1)
Note: The power management IC (PMIC) includes functions to monitor power domains, including over/under voltage, over current, and residual voltage. If the PMIC detects and error, it may transition to ‘safe-mode’ where it powers down both the MCU and MAIN domains.
