7.4 Device Functional Modes
7.4.1 Modes of Operation
SHUTDOWN: The V(VANA) voltage is below VANAUVLO threshold level. All switch, reference, control, and bias
circuitry of the LP8733xx-Q1 device are turned off.
READ OTP:
The main supply voltage V(VANA) is above VANAUVLO level. The regulators are disabled, and
the reference and bias circuitry of the LP8733xx-Q1 are enabled. The OTP bits are loaded to
registers.
STANDBY:
The main supply voltage V(VANA) is above VANAUVLO level. The regulators are disabled, and
the reference, control, and bias circuitry of the LP8733xx-Q1 are enabled. All registers can be
read or written by the host processor through the system serial interface. The regulators can be
enabled if needed.
ACTIVE:
The main supply voltage V(VANA) is above VANAUVLO level. At least one regulator is enabled. All
registers can be read or written by the host processor through the system serial interface.
The operating modes and transitions between the modes are shown in Figure 7-15.
