CAT1232LP/CAT1832 5V and 3.3V Supply Monitor, Watchdog Timer, Manual Reset, with Active High & Low Resets FEATURES s Selectable reset voltage tolerance DESCRIPTION The CAT1232LP and CAT1832 microprocessor supervisors can halt and restart a “hung-up” or “stalled” microprocessor, restart a microprocessor after a power failure, and debounce a manual/push-button microprocessor reset switch. The devices are drop in replacements for the Maxim/Dallas Semiconductor DS1232LP and DS1832 supervisors Precision reference and comparator circuits monitor the 5V or 3.3V system power supply voltage, VCC. During power-up or when the power supply falls outside selectable tolerance limits, both the RESET and RESET become active.
