Detailed Pin Configuration

ADM705ANZ has the following pin configuration:

1. VCC: Supply voltage input
2. GND: Ground reference
3. MR: Manual reset input
4. RESET: Reset output
5. RESET_OUT: Open-drain reset output
6. VBAT: Battery voltage input
7. GND: Ground reference
8. VCC: Supply voltage input

Functional Features

1. Voltage Monitoring: ADM705ANZ continuously monitors the supply voltage and compares it with the preset threshold voltage.
2. Reset Generation: When the supply voltage falls below the threshold, ADM705ANZ generates a reset signal to ensure proper system initialization.
3. Manual Reset: The MR pin allows for manual reset capability, enabling external control over the reset function.
4. Open-Drain Output: The RESET_OUT pin provides an open-drain output for compatibility with different microcontrollers or digital circuits.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality
• Low power consumption
• Wide operating voltage range
• Manual reset capability
• Open-drain output for flexibility

Disadvantages

• Limited reset timeout period (typically 140ms)
• Availability in only one package option (PDIP)

Working Principles

ADM705ANZ operates by continuously monitoring the supply voltage using an internal voltage comparator. When the voltage falls below the preset threshold, the IC generates a reset signal. This signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
