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 LP87332D 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 LP87332D 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 LP87332D are enabled. All registers can be read or
written by the host processor via 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 via the system serial interface.
The operating modes and transitions between the modes are shown in Figure 18.
