The TC1232COA is a fully-integrated Processor Supervisor provides three important functions to safeguard processor sanity - precision power on/off reset control, watchdog timer and external reset override. On power-up, the TC1232 holds the processor in the reset state for a minimum of 250ms after VCC is within tolerance to ensure a stable system start-up. Microprocessor sanity is monitored by the on-board watchdog circuit. The microprocessor must provide a periodic low-going signal on the ST input. The outputs of the TC1232 are immediately driven active when the PB input is brought low by an external pushbutton switch or other electronic signal. When connected to a push button switch, the TC1232 provides contact debounce.
● No external components
● Debounced manual reset input for external override
