The first tri-state buffer IC outputs a second shutdown indicator voltage to the microcontroller that indicates that the first and second plurality of FET switches have been transitioned to the open operational state.

Abstract: A diagnostic system for a DC-DC voltage converter is provided. A first temperature sensor generates a first temperature signal associated with a buck mode integrated circuit. A first analog multiplexer outputs the first temperature signal to a first analog-to-digital converter which generates a first temperature value. A second temperature sensor generates a second temperature signal associated with a boost mode integrated circuit. A second analog multiplexer outputs the second temperature signal to a second analog-to-digital converter which generates a second temperature value. A microcontroller generates control signals to command first and second bi-directional switches in the DC-DC voltage converter to each transition to an open operational state if the first temperature value is greater than a first threshold temperature value.

Abstract: An apparatus for metal plating on a substrate with through-holes includes a chamber that the substrate is disposed inside the chamber to be divided into two sections. A pressure generator and a pressure controller are connected to this and correspond to two sides of the substrate respectively. The pressure generator is used for pumping a electrolyte flowed parallel to the surface of the substrate into the chamber. The pressure controller is used for channeling the electrolyte off the chamber and controlling the pressure differences between the two sides of the substrate. So that the electrolyte flowed parallel to the surface of the substrate is pumped by the pressure generator and it passes several through-holes to control the thickness of metal plating on the.substrate and inner walls of the through-holes.
