ASM1834 Overview
The ASM1834 supervisors simultaneously monitor both 3.3 V and 5 V power sources and generate reset signals when either supply is out of tolerance. When an out−of−tolerance condition is detected, the output−reset signal of the affected supply bees active and resets the system microprocessor/microcontroller. On power−up and after the supply voltage returns to an in−tolerance condition, the reset signal remains active...
