AS1920/AS1922
Datasheet - Detailed Description
8 Detailed Description
The AS1920/AS1922 microprocessor supervisory circuits were designed to generate a reset when at least one of the
three monitored supply voltages falls below its respective trip threshold.
These very-low-current (6.5μA, typ) devices maintain reset for a minimum timeout period after all supplies have stabi-
lized. Guaranteed to be in the correct state for V
CC
> +1.0V, these devices are perfect for multiple-voltage systems with
low current requirements and strict monitoring requirements.
