| This element describes an application where a PSoC device monitors eight different voltage rails and controls the voltage-enables such that they power-on in sequence. |
Many systems require a variety of voltages to power the ASICs, FPGAs, and standard logic found in today's designs. To further complicate the design, some of these devices require voltages to power-on in a specific sequence, lest damage to the chip will occur. There are a variety of voltage monitoring and sequencing devices available today. However, they can be expensive and often do not meet the needs of the design since they offer little or no programmability. A PSoC devices is an excellent choice for monitoring and sequencing the voltages. With its analog structure and programmability, the PSoC can be a perfect fit for the most stringent designs.
