Working Principles

The TL7712ACPG4 operates by continuously monitoring the supply voltage using the SENSE pin. It compares the sensed voltage with a programmable threshold voltage set by the TH pin. If the supply voltage falls below the threshold voltage for a programmable timeout period, the RESET pin is pulled low, indicating a reset condition to the connected microcontroller or digital system. The reset output remains low until the supply voltage rises above the threshold voltage and the timeout period elapses.
