Working Principles

MC34164P-5RPG operates by continuously monitoring the supply voltage. When the voltage falls below the threshold set by the THRES pin, the device generates a reset signal on the RESET pin. This signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin. The CT pin allows adjustment of the reset timeout period, ensuring proper system reset and stability.
