TPS3808G18DBVR Typical application Circuitry

TPS3808G18DBVR

TPS3808G18DBVR is a voltage supervisory circuit chip manufactured by Texas Instruments. This chip is designed to monitor voltage levels and trigger a system reset when these levels fall outside of predefined thresholds. It's particularly useful in applications requiring reliable voltage monitoring and system stability.

Application Scenarios: The TPS3808G18DBVR is frequently utilized in systems like embedded processors, industrial controls, and portable electronics, where consistent and accurate voltage monitoring is crucial for system reliability.

Parameter Features:

- Targeted Voltage Monitoring: Tailored for monitoring 1.8V power supplies.

- Programmable Delay: This feature allows the reset signal to have a delay that may be customized to meet system needs.

- Low Power Consumption: Because of its low power consumption, battery-powered devices can use it.

- Compact Form Factor: Perfect for applications with limited space, this product comes in a tiny SOT-23 box.

- Wide Operating Temperature Range: Capable of operating in a broad range of environmental conditions, making it suitable for diverse applications.

Circuit Connection in Embedded Processor Systems:

1. Power Supply Connection: Connect the VDD pin of TPS3808G18DBVR to the 1.8V power supply line in the embedded system.

2. Grounding the Device: For stability and noise reduction, make sure the TPS380 8G18DBVR's GND pin is correctly connected to the system's ground.

3. Reset Output to Processor: Link the RESET pin of TPS3808G18DBVR directly to the reset input of the embedded processor, ensuring the processor resets when voltage falls below the threshold.

4. Setting the Delay Time: Use an external capacitor connected to the CT pin to program the reset delay time, allowing for flexibility based on the specific timing requirements of the system.

5. Input Voltage Filtering: Place a decoupling capacitor near the VDD pin to stabilize the input voltage and filter out potential noise.

6. Adjusting Voltage Threshold: Calibrate the voltage monitoring threshold of TPS3808G18DBVR to match the critical voltage level for the embedded system.

7. PCB Layout Considerations: Design the PCB layout to minimize the routing distance between TPS3808G18DBVR and the processor, reducing potential signal degradation and interference.

8. Environmental Robustness: Ensure that the placement of TPS3808G18DBVR on the PCB can withstand the environmental conditions typical in embedded system applications, such as temperature fluctuations and potential mechanical shocks.

Design Considerations:

1. Voltage Level Compatibility: Verify that the operating voltage range of TPS3808G18DBVR is in line with the power supply specifications of the embedded system.

2. Reset Timing Precision: Carefully design the delay timing to ensure that the reset signal is issued at the appropriate moment, neither too early nor too late.

3. Power Efficiency: Optimize the circuit for minimal power consumption, crucial for battery-dependent or energy-sensitive embedded systems.

4. Circuit Protection Measures: Incorporate protection elements to shield TPS3808G18DBVR and the overall system from electrical disturbances like transient voltages.

By diligently following these design guidelines and detailed circuit connection instructions for TPS3808G18DBVR, designers can effectively employ this chip in embedded processor systems. This ensures precise voltage monitoring, appropriate system reset functionality, and enhances the overall reliability and stability of the system.
