CY8CKIT-015 PSoC 1 Power Supervision Kit Guide, Doc. # 001-81218 Rev. ** 5
1. Introduction
1.1 Overview
Thank you for your interest in the CY8CKIT-015 PSoC
®
1 Power Supervision Kit. This kit is part of
the PSoC development kit ecosystem and is designed to work with the CY8CKIT-001 PSoC
Development Kit (DVK) and CY8CKIT-035 Power Supervision Expansion Board Kit (EBK). It
enables you to evaluate the system power supervision functions and capabilities of PSoC 1 devices.
You can alter the example project, which is provided with the kit and described in this guide.
In general terms, power supervision is a combination of sequencing, monitoring, and control of
multiple regulators or point-of-load DC power converters in a system. Typical solutions for power
supervision include multiple devices, such as CPLDs, mixed-signal ASICs, and limited-functionality
and inflexible discrete devices. Power supervision solutions require:
■
Fault detection capabilities for high-availability systems
■
Accurate and reliable power rail sequencing of the power converters during power-on and power-
off events
■
Voltage and current measurement of the power converters to optimize power consumption and
for data logging
■
Closed-loop control of the power converters through trimming and, for development and margin-
ing of voltage rails (for manufacturing test purposes)
The PSoC 1 Power Supervision Kit is used with the PSoC family of devices and is specifically
designed and packaged for use with the PSoC 1 device family. PSoC 1 is a programmable system-
on-chip platform that combines programmable analog and digital logic with a proprietary M8C
processor. With the flexibility of the PSoC 1 architecture, you can easily create your own custom
power supervision solution on a chip with the exact functionality you need.
