Abstract: According to examples, an apparatus may include a power circuit to transmit standby power to a device, a memory associated with the device to maintain first configuration data and second configuration data and a battery to provide backup power to the device. The device may, following a loss and a recovery of the standby power to the device, determine whether the backup power was lost during the loss of the standby power. The device may also, based on a determination that the backup power was lost during the loss of the standby power, read the first configuration data or may, based on a determination that the backup power was not lost during the loss of the standby power, read the second configuration data. The device may further apply the read one of the first configuration data or the second configuration data to configure the device.

Abstract: Example implementations relate to controlling a field-effect transistor (FET) switch in a load switch circuit. A digital pulse width modulated (PWM) voltage signal may be applied to a gate of a FET switch. The pulse width of the PWM voltage signal may be set to a first value. The pulse width of the digital PWM voltage signal may be digitally incremented to a second value. The digital PWM voltage signal having the pulse width of the second value may be applied to the gate of the FET switch.

Abstract: Examples disclose a method, system, and computer readable media to configure a device within a computing system. The examples process configuration data when standby power is applied to the device. Additionally, the examples configure the device based on the configuration data, wherein the device is configured prior to initialization of the computing system.
