Zusammenfassung:	The disclosure features systems and methods for protecting transistors of a wireless power receiver. Systems can include a gate driver configured provide a control signal to control switching of the transistor gate such that power is transmitted to a load coupled to the receiver; and a controller coupled to the gate driver and configured to generate a protection signal. The protection signal can include (i) a fault signal indicating a fault in one or more components of the receiver; (ii) a signal indicating that the transistor gate should be latched; and/or (ii) at least one undervoltage signal indicating that an undervoltage condition exists in a power supply of the gate driver. Based on the generated protection signal, the gate driver can be configured to adjust the provided control signal to latch the transistor gate such that power is not transmitted to the load.
