A thermal overload protection circuit and method for protecting switching power amplifier circuits provides protection against latch-up and other failures due to energy returned from an inductive load when the amplifier output is disabled in response to a thermal overload condition. Upon
An over-current protection circuit protection circuit and method for protecting switching power amplifier circuits provides protection against latch-up and other failures due to energy returned from an inductive load when one or more transistors in the amplifier output are disabled in
A protection circuit and method for protecting switching power amplifier circuits during reset provides protection against latch-up and other failures due to energy returned from an inductive load when the amplifier is reset. Upon receipt of a reset indication, rather than immediately
A pulse width modulation circuit for driving a full-bridge output load includes a pulse width modulation stage for generating, from an input data stream, a pulse width modulated data stream for driving a terminal of a full-bridge output load and another pulse width modulated data str
A pre-charge apparatus and method for controlling startup transients in a capacitively-coupled switching power stage provide lower cost and improved startup transient performance in Class D amplifiers, as well as in other AC power converter applications. A charging source is activated
