PRODUCTION DATA
This section provides an overview of each supplies for both user cases: without using Reverse Wakeup and with using Reverse Wakeup. See the Section 7.3.6 for diagnostic control and fault detection on the power supplies block.
NAME | W/O REVERSE WAKEUP USER CASE | W/ REVERSE WAKEUP USER CASE |
---|---|---|
VIO | This supply is powered by regulated 3.3V or 5V from SBC (PMIC), it powers UART/SPI interface pins. | |
BAT | This supply is powered by regulated 5V from SBC (PMIC). | This supply is powered by unregulated 12V battery. |
AVAOREF | This supply is generated from VBAT. It is always on if VBAT exists. It powers REFSYS and Power mode control block. | |
AVDDREF | This supply is derived from AVAOREF. AVDDREF and AVAOREF are connected by a switch, the switch is open in SHUTDOWN mode. | |
DVDD | This supply is generated by the internal DVDD LDO. It is the supply for the digital circuits. It takes the input voltage from CVDD and generates a nominal 1.8V. It will not be used to power any external circuit. | |
CVDD | This supply is powered by regulated 5V from SBC(PMIC). It is the supply for daisy chain interface. | This supply is generated by the internal CVDD LDO. It is the supply for the daisy chain interface (or vertical interface, VIF). It takes the input voltage from VBAT and generates a nominal 5V. It will not be used to power any external circuit. |
