Working Principles

The MAX706ASESA+T operates by continuously monitoring the power supply voltage connected to the VCC pin. When the voltage falls below the selected threshold voltage, the IC generates an active-low reset signal on the RESET pin. This signal can be used to reset the microprocessor or any other system component that requires a reset upon power loss or voltage drop.

The manual reset input (MR) allows for immediate system reset regardless of the monitored voltage level. By asserting a low-level signal on the MR pin, the user can trigger a reset even if the power supply voltage is within the acceptable range.

To set the desired threshold voltage and reset timeout period, appropriate resistors and capacitors are connected to the TH and CT pins, respectively. These external components determine the specific voltage levels and timing characteristics of the reset signal.
