Voltage Supervisors
Integrated circuits that supervise a voltage rail and toggle the status signals when monitored voltage goes online or offline
Voltage supervisors are used to monitor a voltage rail to ensure it is online before asserting a signal to the power supply enable pin allowing the IC to power up. The most common use case for voltage supervisors is that they are paired with microcontrollers and processors that often have multiple supply rails each with a tight window of accuracy. These rails require accurate supervisors to disable the processor when these voltages are out of spec to prevent brownout conditions.
