The working principle and core technical features of TLC34075-85AFN

TLC34075-85AFN is a precision voltage supervisor integrated circuit designed for monitoring the power supply voltage in electronic systems. It provides accurate reset generation during power-up, power-down, and brownout conditions, ensuring proper system initialization and operation.

Core Technology:

The TLC34075-85AFN utilizes a voltage comparator with hysteresis to monitor the input voltage level. It compares the input voltage with a reference voltage, typically set to a threshold slightly below the minimum operating voltage of the system. When the input voltage drops below this threshold, indicating a brownout or power-down event, the reset output is activated to signal the microcontroller or other system components to enter a safe state.

The key features of TLC34075-85AFN include:

- Wide Supply Voltage Range: The device operates over a wide voltage range, typically from 1.6V to 6V, making it suitable for a variety of battery-powered and industrial applications.

- Adjustable Reset Threshold: The reset threshold voltage can be adjusted externally, allowing flexibility in setting the trip point to suit different system requirements.

- Programmable Reset Timeout: The reset output duration can be programmed using an external capacitor, enabling customization of the reset pulse width for specific system needs.

- Low Quiescent Current: The device consumes minimal quiescent current, typically less than 2μA, making it suitable for low-power applications where battery life is critical.

Application Scenario:

In battery-powered IoT devices, TLC34075-85AFN can be used to monitor the supply voltage and initiate a reset sequence when the battery voltage drops below a certain threshold. This ensures proper system operation and prevents data corruption or loss due to unexpected power interruptions.

Circuit Design:

To implement voltage monitoring using TLC34075-85AFN, follow these steps:

1. Power Supply Connection:

Connect the power supply voltage to the VCC pin of TLC34075-85AFN. Ensure proper bypass capacitors are placed near the VCC pin to filter out high-frequency noise.

2. Voltage Monitoring:

Connect the voltage to be monitored to the VIN pin of TLC34075-85AFN. This can be the main system power supply or a voltage divider network for monitoring a specific voltage rail.

3. Reset Output:

Connect the reset output pin (RESET) of TLC34075-85AFN to the reset input of the microcontroller or other system components. This signals the system to enter a safe state during brownout or power-down events.

4. External Components:

Adjust the reset threshold voltage and pulse width by connecting external resistors and capacitors to the appropriate pins of TLC34075-85AFN. Refer to the datasheet for recommended component values.

5. Testing and Validation:

Thoroughly test the circuit under various operating conditions to ensure proper reset generation and system reliability. Verify the reset threshold and pulse width meet the requirements of the application.

Considerations:

When designing with TLC34075-85AFN, consider the following factors:

- Accuracy: Ensure the accuracy of the voltage monitoring circuit to prevent false triggers or missed brownout events.

- System Response: Design the system to respond appropriately to the reset signal, such as saving critical data and shutting down non-essential operations.

- Power Efficiency: Optimize the circuit for low power consumption to maximize battery life in portable or energy-efficient applications.

- Noise Immunity: Minimize noise coupling and interference to ensure reliable operation of the voltage monitoring circuit in noisy environments.

- Environmental Conditions: Consider the operating temperature range and environmental factors when selecting components and designing the circuit layout for robustness and reliability.
