电压监控器
Integrated circuits that supervise a voltage rail and toggle the status signals when the monitored voltage goes online or offline
A voltage supervisor monitors 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. When their voltages are out of spec, the rails need accurate supervisors to disable the processor and prevent brownout conditions. You can rely on Octopart to locate the voltage monitor ICs and other power management integrated circuits your application depends on.
