Application: Circuitry for driving a load (Patent ID: US20240168506A1)
The patent filed by Cirrus Logic Inc. describes circuitry for driving a load, including primary and auxiliary driver circuitry, current detection circuitry, and selectable current sense resistors. The circuitry operates in two modes: a first mode where a playback signal is output to the load, and a second mode where a pilot signal is output. The pilot signal has a predefined frequency and magnitude, while the playback signal drives the load to generate a desired output. The circuitry also includes features such as selectable primary and auxiliary current sense resistors, integrated circuits incorporating the described circuitry, and devices like portable devices, smart speakers, headphones, and wearable devices that can utilize this technology.
The circuitry is designed to efficiently and effectively drive a load by providing different signals in different modes of operation. The primary driver circuitry supplies a playback signal in the first mode, while the auxiliary driver circuitry supplies a pilot signal in the second mode. Current detection circuitry generates signals indicative of the current through the load, allowing for precise monitoring and control. The inclusion of selectable current sense resistors and the ability to operate with a constant DC voltage in the second mode further enhance the functionality and versatility of the circuitry. Overall, the patent outlines a comprehensive system for driving loads that can be integrated into various devices for improved performance and functionality.
