Patent number: 11218823Abstract: A system and method for performing speaker load diagnostics. A digital signal processor generates a diagnostic tone that is provided to the speaker. The diagnostic tone is generated using an oscillator internal to the digital signal processor. The digital signal processor receives current and voltage data from the speaker based on the diagnostic tone, and processes the current and voltage data to determine whether a fault condition exists in the speaker.Type: GrantFiled: October 2, 2019Date of Patent: January 4, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Aditya Polepeddi, Jasjot Singh Chadha, Mukund Navada Kanyana, Sahiti Priya C

Publication number: 20200112787Abstract: A boosted audio amplifier system includes a first digital interpolation filter configured to oversample an audio input signal at a first oversampling rate and includes a signal level detector having an input coupled to receive the oversampled audio input signal and configured to produce an audio input level signal. The system further includes a programmable delay buffer having inputs coupled to receive the oversampled audio input signal and a first delay signal. The programmable delay buffer adds a first delay to the oversampled audio input signal to produce a delayed input signal. The system also includes a first processor having inputs coupled to receive a battery voltage level signal, the audio input level signal and the first delay signal. The first processor is configured to produce boost control signals to regulate a boost voltage.Type: ApplicationFiled: June 18, 2019Publication date: April 9, 2020Inventors: Jasjot Singh Chadha, David Hernandez, Mukund Navada Kanyana, Rejin Kanjavalappil Raveendranath, Sahiti Priya C

Patent number: 10405092Abstract: Brownout management for an audio amplification system. An audio amplification system includes audio volume control circuitry, audio sample interpolation circuitry, and brownout management circuitry. The brownout management circuitry includes brownout detection circuitry and brownout response circuitry. The brownout detection circuitry is configured to determine whether a voltage of a battery that powers the audio amplification system is below a brownout threshold, and to generate a brownout detection signal that indicates the voltage is below the brownout threshold. The brownout response circuitry is coupled to an audio output of the audio sample interpolation circuitry. The brownout response circuitry is configured to attenuate the audio samples output by the audio sample interpolation circuitry responsive to the brownout detection signal indicating that the voltage is below the brownout threshold.Type: GrantFiled: October 1, 2018Date of Patent: September 3, 2019Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Uttam Kumar Agarwal, Prateek Jain, Nageswara Rao, Mukund Navada, Pradeep Chandar Chandramouli
