All switch, reference, control, and bias circuitry of the LP8733xx 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 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 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 22. Figure 22. Device Operation Modes |
