TPS3808G01QDBVRQ1 Typical application Circuitry

TPS3808G01QDBVRQ1

The TPS3808G01QDBVRQ1 is a programmable delay supervisory circuit, designed primarily for voltage monitoring in electronic systems. This TPS3808G01QDBVRQ1 chip plays a crucial role in ensuring system reliability by triggering a reset when voltage levels fall outside the set thresholds, making it particularly valuable in applications that are sensitive to power fluctuations.

Application Scenarios

1. Automotive Electronics: In car control systems to monitor supply voltages and ensure proper functionality during voltage dips.

2. Medical Devices: Ensuring that critical medical instruments operate within safe voltage ranges.

Key Parameters and Characteristics

- Programmable Voltage Threshold: Allows setting specific voltage levels for monitoring.

- Adjustable Reset Delay: Tailors the duration of the reset signal to match system requirements.

- Low Power Consumption: Suitable for applications where energy efficiency is critical.

- High Accuracy Voltage Monitoring: Ensures precise detection of voltage levels.

- Wide Operating Temperature Range: Adaptable to various environmental conditions.

- Compact SOT-23 Package: Ideal for space-constrained applications.

- Power-On Reset Functionality: Automatically initiates a reset when power is first applied.

Detailed Circuit Connection for Automotive Electronics

1. Voltage Monitoring (SENSE Pin): Connect this pin to a critical voltage rail in the automotive system, like the ECU power line.

2. Ground Reference (GND Pin): Secure this pin to the TPS3808G01QDBVRQ1 vehicle's ground to provide a stable reference for voltage monitoring.

3. Reset Output (RESET Pin): Link this pin to the reset input of key automotive controllers or processors. It activates when the sensed voltage drops below the threshold.

4. Chip Power Supply (VDD Pin): Connect this to a stable power source in the vehicle to power the supervisory circuit.

5. Delay Configuration (CT Pin): Attach a capacitor to this pin to set the desired reset signal duration.

6. Manual Reset (MR Pin): Interface this pin with a manual reset button or switch, allowing user-initiated resets.

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

Design Considerations

- Precision in Voltage Threshold: Vital for ensuring accurate monitoring and system protection.

- Energy Consumption: Minimize the impact on the vehicle's overall power budget.

- Timing of Reset Signal: Calibrate the delay to synchronize with the system's recovery processes.

- Environmental Tolerance: Ensure stable operation across the vehicle's operating temperature range.

- Compactness: Efficient integration within the limited space of automotive electronics.

- Noise Immunity: Implement strategies to mitigate electrical noise and prevent false triggering.

- User Accessibility for Manual Reset: Ensure the MR pin is conveniently accessible for manual operation.

Integrating the TPS3808G01QDBVRQ1 into an automotive electronic system requires careful consideration of these factors. TPS3808G01QDBVRQ1 Its role as a voltage supervisor is key in maintaining the operational integrity of vehicles, particularly in environments where consistent performance is essential despite variable power conditions.
