The STM6824LWY6F IC has a total of 6 pins arranged as follows:
```
| | --| VDD GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Reset Output (Active Low) --| WDI |-- Pin 3: Watchdog Input --| MR |-- Pin 4: Manual Reset Input --| VDD |-- Pin 5: Supply Voltage (VDD) |___________| ```
Advantages: - High accuracy in monitoring the supply voltage. - Adjustable watchdog timeout period to suit different system requirements. - Low quiescent current, minimizing power consumption.
Disadvantages: - Limited number of pins for additional functionalities. - Requires an external capacitor for power-on reset delay.
The STM6824LWY6F is designed to ensure reliable operation of electronic systems by monitoring the supply voltage and providing a reset signal when necessary. It operates by comparing the supply voltage with a preset threshold voltage. If the supply voltage falls below the threshold, the reset output becomes active low, indicating a system reset.
Additionally, the IC includes a watchdog timer that requires a periodic input signal (WDI) to be received within a set timeout period. If the input signal is not detected within this period, the watchdog timer triggers a system reset.
The manual reset (MR) input allows for external control of the reset function, enabling a forced system reset when required.
The STM6824LWY6F is widely used in various applications where reliable power management is crucial. Some potential application fields include:
These alternative models offer similar functionalities and can be considered as alternatives to the STM6824LWY6F depending on specific requirements.
