TC1232 Microprocessor Monitor is a fully-integrated processor monitor that provides three important functions to safeguard processor sanity:
• Precision power on/off reset control
• Watchdog Timer, and
• External Reset override
This device is monitored by the on-board watchdog circuit. Providing a periodic low-going signal on the ST input. Whenever it fails to provide or supply signal within the selected time-out period, an out-of-control processor is indicated and the TC1232 issues a processor reset as a result. It’s output are instantly pushed active when the PB input is brought low by an external push button switch or other electronics signal.
This device is packed in a space-saving 8-Pin PDIP or SOIC package, a 16-Pin SOIC package and requires no external components.
It has precision voltage monitor, reset pulse width of 250 ms minimum, with no external components. The watchdog timer is adjustable and is operating a voltage of 4.0V to 5.5V.
