TPS3808G30DBVT Typical application Circuitry

TPS3808G30DBVT

The TPS3808G30DBVT is a programmable delay supervisory circuit or voltage detector. It is designed to monitor voltage levels and trigger a reset in electronic systems if these levels fall outside predetermined thresholds. This TPS3808G30DBVT chip is especially useful in applications that require reliable system reset functionalities to handle undervoltage conditions.

Application Scenarios

1. Consumer Electronics: In devices like smartphones or tablets, it ensures that the system resets safely under low battery conditions or power supply issues.

2. Industrial Control Systems: Monitors power supplies to prevent system malfunctions due to voltage fluctuations.

Key Parameters and Characteristics

Programmable Voltage Threshold: Permits adjustment in accordance with particular system specifications.

- Low Quiescent Current: Perfect for battery-operated gadgets where preserving power is crucial.

Programmable Reset Delay: Allows for customization of the reset signal duration.

- Small Package Size: Suitable for tiny electronic designs.

Detailed Circuit Connection for Smartphone Power Management

1. Voltage Monitoring (SENSE Pin): Connect this pin to the smartphone's battery voltage line or a critical power rail that requires monitoring.

2. System Ground (GND Pin): Link this pin to the TPS3808G30DBVT smartphone's ground to provide a stable reference point.

3. Reset Output (RESET Pin): Connect this pin to the reset input of the main processor or power management IC. It will trigger a reset when the monitored voltage falls below the threshold.

4. Power Supply (VDD Pin): Attach this pin to a stable voltage source, typically the same line being monitored, to power the supervisory circuit.

5. Reset Delay Adjustment (CT Pin): Add a capacitor to this pin to set a specific delay time for the reset signal.

6. Manual Reset (MR Pin): This pin can be connected to a user interface element like a button to manually trigger a system reset.

7. Bypass Capacitor (Between VDD and GND): Place a bypass capacitor close to these pins to stabilize the supply voltage and filter noise.

Design Considerations

- Accurate Voltage Monitoring: Calibration of the voltage threshold is crucial for system protection.

- Power Efficiency: Minimizing power consumption, especially important in battery-operated devices like smartphones.

- Timing Precision: The TPS3808G30DBVT reset delay must be correctly set to ensure proper system recovery.

- Noise Immunity: Filtering and shielding strategies to minimize false triggers.

- Manual Reset Accessibility: Integrating the MR pin effectively for user-initiated resets.

- Compact Design Integration: Placing the chip in a manner that complements the smartphone's compact architecture.

Incorporating the TPS3808G30DBVT into a smartphone involves careful planning around these considerations. Its role in monitoring critical voltages and initiating resets is vital for the reliability and safety of consumer electronics, particularly in devices where consistent performance and power management are critical.
