DS1834A Overview
5-volt supply, 3.3-volt supply, and an external override. First a precision temperature reference and parator circuit monitor the status of the 5-volt supply and the 3.3-volt supply. When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces the reset of the affected supply to an active state.
