In one embodiment, a sequencing system includes a plurality of integrated circuits connected in a daisy chain arrangement, where each integrated circuit has an LED load connection. The system includes a diagnostic circuit which signals to the control unit that an open circuit condition has been detected, thereby turning off all LED loads.

Method of forming a sequencing system and structure therefor

An LED driver circuit and a method for driving the LED driver circuit. In accordance with an embodiment the LED driver circuit includes a voltage follower circuit and a calibration circuit coupled to the voltage follower circuit. First and second currents may be injected into the node and a current is sunk from the node. In accordance with another embodiment, the LED driver circuit asserts a non-zero voltage across the light emitting diode in a first phase of a drive cycle and asserts a fixed non-zero current in the light emitting diode in a second phase of the drive cycle.

LED driver circuit and method

In one embodiment, a method of forming an LED control circuit may include configuring the LED control circuit to receive a sense signal that is representative of a value of an LED current flow through a plurality of LED strings wherein each LED string includes a plurality of series coupled LEDs; configuring a detector circuit of the LED control circuit to detect the LED current being no greater than a first value and responsively initiate forming a first time period; and configuring the LED control circuit to inhibit forming the LED current responsively to termination of the first time period.

Method of forming a semiconductor device and structure therefor

A system and device for providing communications between two or more buses is provided. In one embodiment, the device may comprise a transfer component having a first port configured to be connected to a first bus and a second port configured to be connected to a second bus. The transfer component may be operable in a first operational mode in which signals received via the first port are output the second port and operable in a second operational mode in which signals received via the first port are not output the second port. The device may include a controller communicatively coupled to the transfer component to transition the transfer component between the first and second operational modes.
