Working Principles

The MAX6315US26D2+TG11 operates by continuously monitoring the voltage level of the power supply connected to its VCC pin. When the voltage falls below the threshold voltage set by the TH pin, the IC generates a reset signal on the RESET pin. The reset signal remains active for a user-adjustable timeout period, allowing the system to properly initialize before resuming normal operation. The MR pin can be used to manually trigger a reset if required.
