Patent number: 11937352Abstract: A MOSFET circuit clamps a MOSFET gate voltage (either directly or via a gate control circuit) when the source voltage exceeds a threshold level, for example in response to a voltage surge event between the source and drain. In particular, the gate is held at a voltage relative to the source, to turn off the first MOSFET during such a surge event, but not during normal operation. This provides automatic protection against unwanted increases in the input voltage, especially when the MOSFET was in its on state during the switching. A threshold circuit is connected between a gate (or gate control node) and a reference voltage. When the voltage at the source exceeds a voltage threshold level, it conduct a unidirectional circuit component (D18) between the source and gate (or gate control node), and the threshold circuit.Type: GrantFiled: August 7, 2020Date of Patent: March 19, 2024Assignee: SIGNIFY HOLDING B.V.Inventors: Chenghu Luo, Shaowei Han
