  8. NC (No Connection)

Functional Features

Voltage Monitoring

The TPS3306-15DGK continuously monitors the voltage applied to the VSENSE pin. It compares this voltage against the internal threshold voltage (VIT) and determines whether it is within the acceptable range.

Reset Generation

When the monitored voltage falls below the undervoltage threshold or exceeds the overvoltage threshold, the TPS3306-15DGK generates a reset signal on the RESET pin. This signal can be used to initiate system resets or trigger other appropriate actions.

Manual Reset

The MR pin allows for manual resetting of the device. Pulling this pin low forces the TPS3306-15DGK to generate a reset signal regardless of the voltage level at VSENSE.

Advantages and Disadvantages

Advantages

  • Accurate voltage monitoring ensures system stability.
  • Low power consumption prolongs battery life in portable applications.
  • Wide operating temperature range enables reliable operation in various environments.
