Latest Patents
Wharton McDaniel holds a patent for a current limiting technique for hybrid power MOSFET circuits. This invention involves a power FET and a replica FET on a semiconductor chip, coupled to a logic control circuit on a second semiconductor chip within a single housing. The power FET acts as a switch to connect a DC power source to a load. A portion of the power FET drain current flows through the replica FET and an external resistance. When the voltage across the external resistance surpasses a predetermined maximum, the logic control circuit transitions into a pulsed gate (PG) mode of operation. This mode includes a predefined non-conducting state for both FETs, followed by a ramp voltage application that ensures the power FET operates below its maximum power dissipation limits. The PG mode effectively eliminates the need for additional temperature and thermal control circuits.
