    Microprocessor Monitor
    Features: General Description: Precision Voltage Monitor:
    -Adjustable +4.5V or +4.75V Reset Pulse Width – 250 ms minimum No External Components Adjustable Watchdog Timer:
    -150 ms, 600 ms or 1.2s Operating Voltage 4.0V to 5.5V Debounced Manual Reset Input for External
    Override The TC1232 is a fully-integrated processor supervisor
    that 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 250 ms 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. Should the
    processor fail to supply this signal within the selected
    time-out period (150 ms, 600 ms or 1200 ms), an outof-control processor is indicated and the TC1232
    issues a processor Reset as a result. Block Diagram
