General 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/pushbutton 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 5 V or 3.3 V system power supply voltage, VCC.

During power-up or when the power supply falls outside selectable tolerance limits, both the RESET and R¯¯E¯S¯E¯T¯ become active.

Overview

CAT1232LP, CAT1832 5 V and 3.3 V Supply Monitor, Watchdog Timer, Manual Reset, with Active High & Low.
