ASM1834, ASM1834A, ASM1834D Dual 5 V and 3.3 V mP Power Supply Supervisor with Manual Reset Description 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 for approximately 350 ms. This allows the power supply and system microprocessor to stabilize. Tolerance levels are independently selectable for both supplies. Tolerance...
