Abstract: In a method for driving electronic devices connected to a vehicle trailer tow connector a trailer electronic device control signal is receiving from a vehicle data communication network. In response to the received control signal, a solid state power control device is switched to connect electrical power to a selected pin of the trailer tow connector. The trailer electronic device control signal may be received from a wiring harness connector connected to a vehicle data communication network. A vehicle trailer tow connector module includes a module housing. A vehicle wiring connector and a trailer wiring connector are coupled to the module housing. A power control circuit is connected to a selected pin in the trailer wiring connector. A controller circuit is coupled to the vehicle wiring connector for receiving communication data from a vehicle data bus, and coupled by control lines to the power control circuit.

Abstract: A method includes receiving an activation signal at a semiconductor device and generating an output power signal at the semiconductor device in response to receiving the activation signal. The output power signal has a duty cycle. The method also includes providing the output power signal to a load. The output power signal provides power to the load. An amount of power provided to the load is based on the duty cycle of the output power signal. In addition, the method includes adjusting the duty cycle of the output power signal using at least one of a current limiter and a power limiter integrated in the semiconductor device.

Abstract: Existing current sense outputs in a power switch can be utilized to output fault diagnosis information. Current sense circuitry that normally drives the current sense output can be disabled, thereby permitting the fault diagnosis information to be output. An existing fault indicator output can be controlled for bidirectional operation, thereby permitting an external controller to control the output of fault diagnosis information on the existing current sense output.

Abstract: A universal vehicle electric power distribution module employs reconfigurable inputs and outputs enabling use of the same hardware across vehicle lines. The module is scalable for ease of expansion and is capable of handling both low current and high current load management on the same module.
