Product details

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 becomes active and resets the system microprocessor/microcontroller. up and after the supply voltage returns to an in tolerance condition, the reset signal remains active for approximately 350 ms.
