This is an Obsolete Application Note
The document AN2379 - PSoC® 1 Power Management - Voltage Monitoring and Sequencing with PSoC and I2C has been marked as obsolete. The obsolete version of this application note is still available with the below description but may not be complete or valid any longer. If you have any questions or require support in regards to the below application note content, please click here and create a technical support case.

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 device 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. AN2379 is an updated and enhanced version of AN2154 and includes, by request, I2C.
