The working principle and core technical features of DS3904U-010+T&R

DS3904U-010+T&R is a precision voltage supervisor with adjustable threshold, commonly used in power management systems for voltage monitoring and reset generation. It features a low quiescent current, wide operating voltage range, and programmable reset delay timer.

Application Scenario:

In battery-powered devices, DS3904U-010+T&R can be employed to monitor the battery voltage and generate a reset signal when the voltage falls below a certain threshold, ensuring proper system operation and preventing data corruption or loss due to low battery voltage.

Circuit Design:

To design a battery voltage monitoring and reset circuit using DS3904U-010+T&R, follow these steps:

1. Voltage Monitoring:

Connect the battery voltage to the VIN pin of DS3904U-010+T&R. Use external resistors to set the desired voltage threshold for monitoring.

2. Reset Signal Generation:

Connect the RESET pin of DS3904U-010+T&R to the reset input of the microcontroller or system processor. When the monitored voltage falls below the threshold, the reset signal is asserted, initiating a system reset.

3. Reset Delay Timer:

Program the reset delay timer of DS3904U-010+T&R to add a delay between the voltage falling below the threshold and the generation of the reset signal. This prevents false resets due to brief voltage dips or fluctuations.

4. Power-On Reset:

Utilize the POR (Power-On Reset) feature of DS3904U-010+T&R to generate a reset signal upon power-up, ensuring a controlled start-up sequence and proper initialization of the system.

5. Fault Detection:

Monitor the FAULT pin of DS3904U-010+T&R to detect any fault conditions, such as undervoltage or overvoltage events, and take appropriate actions to ensure system safety and reliability.

Considerations:

When designing the circuit, it's essential to consider:

- Voltage Threshold Accuracy: Ensure accurate setting of the voltage threshold to trigger the reset signal at the desired battery voltage level.

- Reset Pulse Width: Set the reset pulse width according to the requirements of the microcontroller or system processor to ensure proper reset operation.

- Battery Monitoring Range: Select appropriate resistor values to accommodate the expected range of battery voltages and ensure reliable operation over the entire battery life cycle.

- Low Power Consumption: Minimize the quiescent current of DS3904U-010+T&R to conserve battery power and extend the operating time between battery replacements or recharges.

- System Integration: Integrate DS3904U-010+T&R seamlessly into the overall system design, considering factors such as PCB layout, component placement, and system interconnectivity.
