Working Principles

The MAX16058ATA31+T is designed to monitor the supply voltage of microcontrollers and other digital systems. It compares the input voltage with a user-selectable threshold voltage (TH) and generates a reset signal if the voltage falls below the threshold. The reset timeout period can be adjusted to control the duration of the reset signal.

The device operates by continuously monitoring the voltage on the TH pin. If the voltage drops below the programmed threshold, the internal reset circuitry is activated, generating a reset pulse on the RESET_OUT pin. This reset pulse remains active until the voltage rises above the threshold or the programmable timeout period elapses.
