WAKEUP CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240077932 titled 'WAKEUP CIRCUIT

Simplified Explanation

The present disclosure describes a system with a power management device, a wakeup circuit, a battery management device, and a connector. During a powered down mode of operation, the battery management device can provide, via the connector, a bias voltage to the wakeup circuit. In response to a wakeup switch being activated, the battery management device can provide a power supply (e.g., from a battery) to the power management device. Benefits of the wakeup circuit include (1) a reduction of battery consumption—and thus improving battery lifetime—when the electronic system is in a powered down mode of operation because the wakeup circuit has lower number of active components compared to other designs and (2) a non-complex wakeup circuit design because one or more existing connector interconnects between the power management device and the battery management device can be re-used during electronic system's powered down mode of operation.

• Lower battery consumption due to fewer active components in the wakeup circuit
• Simplified wakeup circuit design by re-using existing connector interconnects
• Improved battery lifetime during powered down mode of operation

Potential Applications

The technology described in the patent application could be applied in various electronic devices that require efficient power management and battery usage, such as smartphones, tablets, laptops, and IoT devices.

Problems Solved

1. Reduced battery consumption during powered down mode of operation 2. Simplified design of the wakeup circuit

Benefits

1. Improved battery lifetime 2. Efficient power management 3. Cost-effective design

Potential Commercial Applications

The technology could be utilized in consumer electronics, medical devices, industrial equipment, and automotive systems to enhance battery performance and optimize power usage.

Possible Prior Art

One possible prior art could be the use of separate wakeup circuits and power management devices in electronic systems, which may not be as efficient in terms of battery consumption and design simplicity.

What are the technical specifications of the system described in the patent application?

The technical specifications of the system, such as the voltage levels supported, the power management capabilities, and the communication protocols used, are not detailed in the abstract. Further information from the full patent application document would be needed to understand the specific technical aspects of the system.

How does the system ensure compatibility with different types of batteries and power sources?

The abstract does not provide information on how the system ensures compatibility with different types of batteries and power sources. This aspect of the technology would need to be explored further in the full patent application to understand how the system addresses compatibility issues.
