Opis
The CAT1232LP and CAT1832 microprocessor supervisors can halt and restart "crashed" or "stalled" microprocessors, restart microprocessors after power failures, and debounce manual/push-button microprocessor reset switches. These devices are direct replacements for Maxim/Dallas Semiconductor DS1232LP and DS1832 supervisors. A precision reference and comparator circuit monitors the 5V or 3.3V system supply voltage VCC. During power-up or when the supply voltage goes out of the selectable tolerance range, both RESET and RESET (overline) are asserted. After the supply voltage rises above the RESET threshold voltage, the reset signal remains active for a minimum of 250ms, allowing the power supply and system processor to stabilize. The trip-point tolerance input TOL selects either 5% or 10% trip-point tolerance for the CAT1232LP 5V supply, and either 10% or 20% trip-point tolerance for the CAT1832 3.3V supply. Each device features a push-pull, active-high reset output. The CAT1232LP also includes an open-drain, active-low reset output, while the CAT1832 also includes a push-pull, active-low reset output. The debounced manual reset input asserts the reset outputs and holds them active for a minimum of 250ms after release. A watchdog timer is also included to reset microprocessors that have stopped operating due to software or hardware faults. Three watchdog timeout periods are selectable: 150ms, 600ms, and 1.2s. If the ST (overline) input is not pulled low before the watchdog timeout period expires, the reset signal remains active for a minimum of 250ms.
