Functional Features

Undervoltage and Overvoltage Monitoring

The TPS3306-25DGKG4 continuously monitors the input voltage and compares it with the user-programmed threshold levels. If the voltage falls below or exceeds the set thresholds, the device generates a reset signal to indicate an undervoltage or overvoltage condition.

Manual Reset Capability

The MR pin allows for manual resetting of the device. When this pin is pulled low, the reset output is activated, regardless of the monitored voltage level.

Adjustable Thresholds

Users can configure the desired voltage thresholds by connecting appropriate resistors to the TH pin. This flexibility enables customization based on specific application requirements.

Power-On Reset Delay

Upon power-up, the TPS3306-25DGKG4 incorporates a built-in delay circuit that ensures a stable power supply before monitoring begins. This feature prevents false reset signals during system startup.

Advantages and Disadvantages
