Abstract
An audio or haptic power output system manages and delivers power to multiple output transducers based on corresponding power or current limits that are adjusted dynamically according to measures of power or current that are required to generate power output signals from corresponding digital input values or signals. A power management subsystem controls electrical power or current consumed by power output stages that supply power to the transducers by comparing the measures of power or current required to generate the power output signals to the corresponding power or current limits, and limiting the power or current consumed by the individual power output stages measures of power or current exceeds the corresponding limits.
