A method for signaling between a controller and a driver includes receiving, at a pin of the driver coupled to the controller, a command signal generated by the controller and generating, by the driver at the pin coupled to the controller, a fault signal indicating a fault condition. The driver can be configured to drive a switch and the command signal can be configured to cause the driver to open the switch when the command signal is in a first state and to close the switch when the command signal is in a second state. The command signal being in the first state may correspond to the command signal having a voltage level above a first predetermined threshold and the command signal being in the second state may correspond to the command signal having a voltage level below a second predetermined threshold.
