AN-1058 GreenPAK Macro Circuit Design Failsafe Watchdog

The stability of the power supply voltage is an important factor in microprocessor based systems. With instability, the best case means a restart of the system is possible. But at worst case it may mean a failure/malfunction of the program that may cause some unexpected outcome. As a result, many manufacturers employ shutdown in their microcontrollers. There still are cases when that may be not enough. As a solution, there are specific IC’s that can control the power supply and restart a system if necessary. The H6006 (produced by EM Microelectronic-Marin SA) is an example of such an IC.
