This article provides steps to follow when implementing a processor-supervisor circuit. Choosing an appropriate microprocessor-supervisor integrated circuit can be quiet a task. The first step in selecting a supervisor is to determine the voltage at which it starts its delay timer. The second step is to determine the time interval between the supply voltage reaching its threshold value. Next is to select the output logic. The last step is to determine what additional features are required.
