Another app note from MAXIM Integrated utilizing supervisory chip and LEDs to indicate voltage faults. Link here Traditionally, supervisory ICs have been used to monitor voltage rails for undervoltage faults (UV). When a supply rail falls below a set threshold, the system is held in reset using the reset output signal to the microcontroller to […]

App note: Using the enable Pin in a linear regulator as a voltage supervisor
Clever way using linear regulator’s enable pin implementing a voltage supervisory circuit control, an app note(PDF) from ON Semiconductors. The combination of a voltage regulator and a voltage supervisor, is a popular circuit configuration. The addition of the supervisor ensures that the regulated output turns on and off at sufficient input voltages, as well as […]
