ADM690ANZ

The ADM690ANZ is a precision voltage supervisor and reset controller manufactured by Analog Devices Inc., previously known as Maxim Integrated. This device is designed to monitor power supply voltages and ensure that microcontrollers and other digital circuits operate reliably by providing a reset signal during power-up, power-down, and brownout conditions.

Key Features:

1. Voltage Monitoring: The ADM690ANZ monitors the supply voltage and generates a reset signal when the voltage falls below a predetermined threshold. This ensures that the connected microcontroller or digital logic does not operate under unsafe voltage conditions.

2. Reset Output: The device features an active-low reset output (RESET) that remains low during power-up and power-down sequences, ensuring that the system does not start operating until the supply voltage is stable.

3. Adjustable Reset Threshold: The reset threshold voltage can be set to various levels, allowing flexibility in design. This is particularly useful for applications with different supply voltages.

4. Fast Response Time: The ADM690ANZ has a fast response time to voltage changes, which helps in quickly asserting the reset signal when the supply voltage drops below the threshold.

5. Low Power Consumption: The device is designed to operate with low power consumption, making it suitable for battery-powered applications.

6. Temperature Range: The ADM690ANZ operates over a wide temperature range, making it suitable for various environmental conditions.

7. Compact Package: The device is available in a small 8-lead SOIC package, which is ideal for space-constrained applications.

Applications:

• Microcontroller Reset: The ADM690ANZ is commonly used in microcontroller-based systems to ensure that the microcontroller starts in a known state.
• Power Supply Monitoring: It can be used in power supply circuits to monitor voltage levels and provide reset signals to downstream components.
• Consumer Electronics: The device is suitable for use in consumer electronics where reliable operation is critical.
• Industrial Equipment: It can be employed in industrial applications to ensure that equipment operates safely under varying voltage conditions.

Electrical Characteristics:

• Supply Voltage Range: The ADM690ANZ typically operates within a specified voltage range, ensuring compatibility with various power supply designs.
• Reset Threshold Voltage: The specific reset threshold voltage can be selected based on the application requirements, providing versatility in design.

Conclusion:

The ADM690ANZ from Analog Devices Inc. is a robust and reliable voltage supervisor and reset controller that plays a crucial role in ensuring the safe operation of electronic systems. Its combination of adjustable thresholds, fast response times, and low power consumption makes it an excellent choice for a wide range of applications in both consumer and industrial electronics.
