Detailed Pin Configuration

ADM695ARZ has the following pin configuration:

1. VCC: Power supply input
2. GND: Ground reference
3. MR: Manual reset input (active-low)
4. RESET: Reset output (active-low)

Functional Features

1. Voltage Monitoring: ADM695ARZ continuously monitors the supply voltage and compares it with the preset threshold voltage.
2. Reset Signal Generation: When the supply voltage drops below the threshold, ADM695ARZ generates an active-low reset signal.
3. Manual Reset: The manual reset input (MR) allows for an external reset signal to override the voltage monitoring function.
4. Power-On Reset: ADM695ARZ ensures a reliable reset during power-up, preventing any undefined behavior of the connected circuitry.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Wide supply voltage range allows for versatile applications
• Low quiescent current minimizes power consumption
• Small package size enables space-efficient designs

Disadvantages

• Limited threshold voltage options may not suit all applications
• Active-low reset signal may require additional level-shifting circuitry in certain systems

Working Principles

ADM695ARZ operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the preset threshold, it triggers the generation of an active-low reset signal. This signal remains active until the supply voltage rises above the threshold again. The manual reset input (MR) allows for an external reset signal to override the voltage monitoring function.

Detailed Application Field Plans

ADM695ARZ finds applications in various electronic devices where reliable voltage monitoring and reset functionality are crucial. Some common application fields include:

1. Microcontrollers: Ensuring proper initialization and operation of microcontrollers after power-up or brownout conditions.
2. Embedded Systems: Providing a reliable reset mechanism for embedded systems to prevent erratic behavior.
3. Industrial Control Systems: Monitoring and resetting critical control circuits in industrial automation systems.
4. Power Supply Units: Protecting sensitive components by initiating a reset when the supply voltage drops below a safe threshold.
