Functional Features

Voltage Monitoring

The TPS3306-18DR continuously monitors the voltage applied to the SENSE pin. It compares this voltage with the threshold voltage set by the TH pin.

Reset Generation

When the monitored voltage falls below the threshold voltage, the TPS3306-18DR generates a reset signal on the RESET pin. This signal can be used to initiate system reset or trigger other actions.

Manual Reset

The MR pin allows for manual reset functionality. When pulled low, it forces the TPS3306-18DR to generate a reset signal regardless of the monitored voltage level.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures system stability.
• Low power consumption prolongs battery life in portable devices.
• Wide operating temperature range enables usage in various environments.
• Compact package facilitates easy integration into electronic systems.

Disadvantages
