Hi All,

 

Embedded systems industry are tending to optimized their products to offers a better performance in power management, aiming for longer battery life, using low-power modes in the application without reducing functionality. With this in mind, it arises a requirement in these compact devices, power supply monitor.

 

This document will include a brief description of some features available in different power modes of the Kinetis family and it will focus on how we can implement these features, using KSDK 2.0, to monitor power supply voltage and detect when this voltage has fallen at determined value. This document is based MCU K21 but the same principles can be applied to any Kinetis K and L family. It will use KDS 3.2 as IDE and TWR-K21F120M evaluation board as target.

 

 

Hope you can find it useful

Best Regards

Jorge Alcala
