Working Principles

The MAX16056ATA31+T is designed to monitor the voltage level of a power supply and generate a reset signal when the voltage falls below a certain threshold. It operates by comparing the input voltage (VCC) with the selected threshold voltage (TH). When VCC drops below TH, the reset output (RSTOUT) is pulled low, indicating a system reset condition.

The reset timeout period can be adjusted using an external capacitor connected to the MR pin. This allows designers to fine-tune the duration of the reset signal according to their specific application requirements.
