The IMP1832 microprocessor supervisor 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 IMP1832 features over 40% lower supply current than the pin compatible Dallas Semiconductor DS1832.
