The audio system implements one or more techniques for ensuring a transistor within the H-bridge does not turn on in the event of the detection of a short-circuit on the output of the H-bridge. Other transistors within the H-bridge can turn and thus audio can still be played to a speaker.

Abstract: A controller regulates the voltage delivered to the load and current drawn from the battery in an audio system depending on ripple in the battery voltage which is input to the controller to allocate power for audio playback. Regulation maximizes available headroom while avoiding audio clipping. The effect of internal battery and external parasitic resistance (ESR) on ripple is compensated by an iterative process. ESR is rapidly increased whenever the minimum of the battery voltage input to the controller falls below a clipping threshold and slowly decreased whenever such voltage exceeds such threshold and the audio is under compression. A limiter allocates power to utilize more of the available audio headroom. A de-emphasis filter in each audio signal path compensates for capacitive ripple in the battery voltage input to the controller. As the frequency of the audio input changes, the filter(s) allow frequency-dependent power/current regulation to fill the full audio range without distortion.

Abstract: Techniques are provided herein for generating PWM signals. Furthermore, a direct-drive method is disclosed in which a PWM signal is generated as a differential signal made up of OUTP and OUTN signals, where OUTP is a copy of OUTN but shifted in time by half a period. The PWM signal is generated by passing each of an input period and an input duty cycle through corresponding sigma-delta circuits to generate a refined period and a refined duty cycle, respectively. In some example cases, a threshold mapper uses a lookup table (LUT) or similar mechanism to select timing thresholds for rise times and fall times for each of the OUTP and OUTN signals, where the timing thresholds are selected based on the refined period and the refined duty cycle. In some example cases, a pulse generator generates the OUTP and OUTN signals based on the timing thresholds.

Abstract: A circuit includes a comparator to compare an analog signal to a ramp signal to generate a pulse width modulated output signal and a driver to generate control signals for a plurality of power transistors. A pulse blanking circuit receives the pulse width modulated output signal. For each pulse of the pulse width modulated output signal, the pulse blanking circuit, responsive to a width of the pulse being greater than a threshold, passes the pulse to the driver. Responsive to the width of the pulse being less than the threshold, the pulse blanking circuit prevents the pulse from being passed to the driver.
