Abstract
An over-power protection circuit for a MOSFET includes an over-current protection circuit and a current limit setting circuit, and an over-power protection circuit configured to continuously monitor a voltage across the MOSFET being protected to prevent over-power conditions, and to dynamically determine a maximum current limit based on the monitored voltage and a pre-set maximum power limit.
