NCP1232
NCP1232 is Microprocessor Monitor manufactured by onsemi.
Microprocessor Monitor
The NCP1232 is a fully-integrated processor supervisor. It provides three important functions to safeguard processor functionality: precision power on/off reset control, watchdog timer and external reset override.
On power-up, the NCP1232 holds the processor in the reset state for a minimum of 250 msec after VCC is within tolerance to ensure a stable system start-up.
Microprocessor functionality is monitored by the on- board watchdog circuit. The microprocessor must provide a periodic low-going signal on the ST input. Should the processor fail to supply this signal within the selected time-out period (150 msec, 600 msec or 1200 msec), an out- of- control...
