Voltage Supervisors 101

Window Detector and Watchdog Timer

This video will cover the watchdog and window detector feature offered with voltage supervisors. Specifically, we will highlight the standard and window watchdog timer to show its importance in processors and microprocessors. Additionally, we will highlight important features on the datasheet that affect the performance of the watchdog timer. We will also cover the window detector, which can detect both over and undervoltage conditions (OV/UV).

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.
Applications of voltage supervisors (reset ICs)

Voltage supervisor fundamentals and design considerations

Voltage supervisors increase the system reliability and robustness by ensuring that power rails are active only during stable power supply. This is achieved through functions such as: precise voltage monitoring, over-voltage protection, power failure indicator, processor monitoring, power sequencing, battery backup, and reset latching.

 In this series, you will learn about the:

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.

Applications of voltage supervisors in grid infrastructure

Leakage current detection is necessary in most of the industrial and residential breakers as well as in many EEQ such as EV chargers, PV inverters etc. In this course we’ll deep dive into circuit breakers and review TIDA-010041 reference design that provides an easy and efficient method of detecting residual current or ground fault by leveraging voltage supervisor IC. This solution also finds application in over-voltage detection in binary input module EEQ. In addition, this also includes power sequencing using supply voltage supervisors.
