Working Principles

The MAX16073RS31D2+T is a voltage supervisor IC that continuously monitors the supply voltage. When the voltage falls below the selected threshold, it generates an active-low reset signal. This signal can be used to reset microcontrollers, processors, or other system components.

The device also includes a manual reset input (MR) which, when pulled low, forces an immediate system reset. This feature is useful during system testing or debugging.

The MAX16073RS31D2+T operates with low quiescent current, making it suitable for battery-powered applications. Its small package size allows for easy integration into space-constrained designs.
