Analog Devices power supply voltage monitors and microprocessor supervisors monitor positive and negative power supplies, with integration of up to eight supply monitors in a tiny package. These devices generate a reset signal if any power supply goes above or below the user-defined threshold. Reset times are usually fixed at 200 ms or are adjustable with a single capacitor. Aside from power supply monitoring, CPUs and ASICs can also be supervised by an integrated watchdog timer.
