Working Principles

The MAX16072RS29D2+T is a voltage supervisor IC that monitors the supply voltage of microcontrollers and other digital systems. It compares the supply voltage with a user-selectable threshold voltage and generates a reset signal when the supply voltage falls below the threshold.

The threshold voltage can be set using the TH pin, allowing the device to accommodate different voltage requirements. The reset timeout period can also be adjusted using external components, providing flexibility in system design.

In normal operation, the MAX16072RS29D2+T continuously monitors the supply voltage. If the voltage drops below the threshold, the active-low RESET pin is asserted, indicating a power failure or low voltage condition. The reset remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

The manual reset (MR) input allows an external signal to force a reset, overriding the voltage monitoring function. This feature is useful during system testing or when a controlled reset is required.
