ASM1834A Overview
The ASM1834 supervisors simultaneously monitor both 3.3V and 5V 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...
