Working Principles

The MAX16039LLA23+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the programmable threshold, it triggers the reset signal generation circuitry. The reset signal remains active until the supply voltage rises above the threshold or the programmable timeout period elapses. The manual reset input allows the system to be reset manually if required.
