Detailed Pin Configuration

The APX803-46SAG-7 has three pins:

1. VDD - Power supply input
2. GND - Ground reference
3. RESET - Output pin for reset signal

Functional Features

• Voltage monitoring: The APX803-46SAG-7 continuously monitors the input voltage and provides a reset signal when it falls below the specified threshold.
• Reset function: When the input voltage drops below the threshold, the RESET pin goes low, indicating a system reset condition.
• Power-on reset delay: The device ensures a stable reset signal by delaying the output until the power supply voltage reaches a stable level.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system performance.
• Wide operating voltage range allows for compatibility with various electronic systems.
• High accuracy ensures reliable voltage monitoring and reset functionality.
• Small package size enables space-saving integration into compact designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages
