STM809SWX6F Typical application Circuitry

STM809SWX6F

The STM809SWX6F is a microprocessor reset circuit chip, designed primarily for monitoring power supply and system health in digital systems. This chip is part of STMicroelectronics' portfolio of reset circuits and is widely used in applications where reliable system behavior is critical, especially during power-up, power-down, or brown-out conditions.

Application Scenarios

A typical application of the STM809SWX6F is in embedded systems, such as microcontroller-based consumer electronics, where it ensures proper system reset during power fluctuations.

Parameter Features

- Precision monitoring of 3.08V power supply (V_th)

- Low power consumption

- Active-low, push-pull RESET output

- Reset pulse duration of 140 ms minimum

- Operating temperature range from -40°C to +85°C

Circuit Connection Example-Embedded System Reset Circuit

1. Power Supply Monitoring: Connect the VCC pin of STM809SWX6F to the power supply line (3.3V, for instance) that you want to monitor.

2. Reset Output: The RESET pin is the active-low output. Attach this pin to the microcontroller or system you are watching's reset input.

3. Ground Connection: Connect the GND pin to the system ground.

4. Bypass Capacitor: Place a small (e.g., 0.1 µF) ceramic capacitor close to the STM809SWX6F between VCC and GND to filter out voltage spikes and noise.

Design Considerations

1. Voltage Threshold Accuracy: Ensure the power supply voltage is within the threshold range of the STM809SWX6F for accurate monitoring.

2. Reset Signal Compatibility: The reset signal from STM809SWX6F must be compatible with the microcontroller or system it's connected to.

3. Power Supply Noise: Minimize noise on the power supply line to prevent false triggering of the reset circuit.

4. Placement and Routing: Place the STM809SWX6F close to the power entry point of the board and ensure minimal trace length to the monitored system for quick and reliable response.

In conclusion, the STM809SWX6F is an essential component for ensuring reliable system operation in digital systems, especially those susceptible to power supply irregularities.When designing a circuit utilizing this chip, factors including noise reduction, signal compatibility, voltage thresholds, and positioning must all be carefully considered.
