Detailed Pin Configuration

APX809S00-29SA-7 has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Voltage Monitoring: APX809S00-29SA-7 continuously monitors the input voltage and provides a reset signal when it falls below the specified threshold.
• Reset Generation: When the monitored voltage drops below the threshold, the RESET pin goes low, indicating a reset condition.
• Reset Timeout: The reset signal remains active for a specific timeout period, allowing the system to stabilize before resuming normal operation.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system performance.
• Wide operating voltage range makes it compatible with various electronic devices.
• High accuracy ensures reliable voltage monitoring.
• Small package size allows for space-saving integration in compact designs.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer stabilization times.
• Lack of adjustable threshold voltage limits customization options.

Working Principles

APX809S00-29SA-7 operates based on a voltage comparator circuit. It compares the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the comparator triggers the reset signal, indicating a low-voltage condition. The reset signal remains active for the specified timeout period, allowing the system to stabilize before resuming normal operation.

Detailed Application Field Plans

APX809S00-29SA-7 finds applications in various electronic systems where voltage monitoring and reset functions are critical. Some common application fields include:

1. Microcontrollers: Ensuring proper voltage levels for reliable operation.
2. Power Supplies: Protecting sensitive components from undervoltage conditions.
3. Battery-Powered Devices: Preventing damage due to excessive discharge.
4. Industrial Control Systems: Maintaining stable voltage levels for uninterrupted operation.
