uP Supervisory IC Manufacturers

Supervisory ICs are integrated circuits that monitor the condition of microprocessors.
So Supervisory Chips offer a support function monitoring voltages and timing.
Some Supervisory ICs might be designed to monitor the speed of a fan, and have no other function. Other ICs might just monitor the state or voltage level of a battery.
What ever the functionality of the circuit, the common aspect of the chip is having one or more connections back to a uP to inform the processor to power down, reset or take some other corrective action. Although most Supervisory ICs are really just voltage monitors used to insure that the power supplies [voltage rails] on a card ramp up correctly. In fact some companies segment their products by the number of voltage lines that can be monitored.
