```

---

| | --| VDD | --| GND | --| MR | --| RESET | |___________| ```

• VDD: Power supply input
• GND: Ground reference
• MR: Manual reset input (active low)
• RESET: Reset output (active low)

Functional Features

1. Voltage Monitoring: The TPS3110K33DBVRG4 continuously monitors the input voltage level.
2. Threshold Detection: When the voltage falls below the threshold voltage (3.08V), the IC triggers a reset signal.
3. Reset Signal Generation: The IC generates an active low reset signal to the microcontroller or other digital devices connected to the RESET pin.
4. Reset Timeout: After the voltage rises above the threshold, the reset signal remains active for a fixed timeout period of 200ms.
5. Manual Reset: The MR pin allows for manual reset by pulling it low.

Advantages and Disadvantages

Advantages: - Ensures reliable operation of electronic systems by monitoring voltage levels - Prevents data corruption and system malfunction due to low voltage conditions - Compact SOT-23 package for space-constrained applications - Wide operating temperature range (-40°C to +85°C) - Low quiescent current consumption (10µA)

Disadvantages: - Requires an external pull-up resistor for the RESET pin - Limited to a specific threshold voltage (3.08V)

Working Principles

The TPS3110K33DBVRG4 operates by comparing the input voltage with a predefined threshold voltage. When the input voltage falls below the threshold, the IC triggers a reset signal. This signal remains active for a fixed timeout period of 200ms after the voltage rises above the threshold. The reset signal is then deactivated, allowing the microcontroller or other digital devices to resume normal operation.

Application Field Plans

The TPS3110K33DBVRG4 finds applications in various electronic systems where voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Embedded Systems: Used in microcontroller-based systems to ensure proper functioning during power fluctuations.
2. Automotive Electronics: Monitors voltage levels in automotive control units to prevent system failures.
3. Industrial Control Systems: Provides voltage supervision in industrial automation equipment to maintain system integrity.
4. Telecommunications: Ensures reliable operation of communication devices by monitoring voltage levels.
5. Consumer Electronics: Used in portable devices to prevent data corruption during low battery conditions.

Alternative Models

1. TPS3110K33DBVR: Similar to TPS3110K33DBVRG4 but without the reel packaging.
2. TPS3110K33DBVT: SOT-23 package variant with a different threshold voltage (3.3V).

These alternative models offer similar functionality and can be considered as substitutes for the TPS3110K33DBVRG4 depending on specific requirements.
