Silicon Laboratories had three patents in advanced materials during Q2 2024. The patent describes a battery-powered device sealed in an enclosure with a photovoltaic device that activates the controller to transition the device from shelf mode to active mode. The enclosure has a transparent portion for external optical signals and can be obstructed by an opaque label. The controller can configure a terminal as an output to keep the device in active mode and use the activation signal to return the device to shelf mode.

Application: Wake-up for battery-powered device (Patent ID: US20240163794A1)
The patent filed by Silicon Laboratories Inc. describes a battery-powered device sealed in an enclosure with a photovoltaic device that converts light to an electrical signal to activate the controller and transition the device from a shelf mode to an active mode. The enclosure has a transparent portion for passing external optical signals to the photovoltaic device, which may be obstructed by a removable, opaque label. The controller configures a general-purpose input-output terminal as an output to maintain the active level of the activation signal, keeping the device in the active mode, and can also return the device to shelf mode using the activation signal.
The patent claims detail an integrated circuit product with an energy harvesting circuit, a controller transitioning from ultra-low power to active mode in response to an activation signal, and a feedback circuit maintaining the activation signal at an active level. The energy harvesting circuit uses visible light to provide the activation signal, and the enclosure includes a transparent portion for passing the electromagnetic signal. The controller can execute instructions to maintain the active level of the activation signal, couple to a battery, and return to low-power mode after a predetermined time of inactivity, providing an efficient and innovative power management system for battery-powered devices.
