Voltage Supervisors 101

Interested in Voltage Supervisors, Voltage Monitors, Voltage Detectors, and Reset ICs? Learn about the basics with this Voltage Supervisors 101 training series. Many people confuse voltage supervisors with voltage monitors, voltage detectors, and reset ICs; however, these devices are all the same. This training series will cover a wide range of topics covering the introduction to supervisors to understanding the key specifications and features that a supervisor can bring to your subsystem. Pick any supervisor topic from this training series that you're interested in and learn today. Remember that whenever there is a voltage rail, a supervisor should be utilized to ensure that the system is able to execute safely and avoid brownout conditions. 

1. Overview of the Voltage Supervisor

In this video, learn about what a voltage supervisor is and discover the common use cases of voltage supervisors. Voltage supervisors are commonly paired with DC/DC converters, LDOs, and Processors/MCU’s in order to monitor the voltage rail. We will also highlight how a supervisor works in order to protect your subsystem from brownout. Remember, a voltage supervisor is the same as a voltage detector, voltage monitors, and reset ICs.
