Detailed Pin Configuration

The ADM805LANZ has the following pin configuration:

1. VCC: Power supply input
2. GND: Ground reference
3. RESET: Active-low reset output
4. MR: Manual reset input
5. RESET: Active-low reset output
6. GND: Ground reference
7. VCC: Power supply input

Functional Features

1. Voltage monitoring: The ADM805LANZ continuously monitors the power supply voltage.
2. Reset signal generation: When the voltage falls below the specified threshold, the IC generates an active-low reset signal.
3. Manual reset: The MR pin allows for manual reset control, overriding the automatic reset function.
4. Power-on reset delay: The IC provides a delay to ensure stable power supply before generating the reset signal.

Advantages and Disadvantages

Advantages

• Precise voltage monitoring ensures reliable system operation.
• Low power consumption extends battery life in portable applications.
• Small package size enables compact designs.
• Wide operating temperature range allows for use in various environments.

Disadvantages

• Limited reset threshold voltage options may not suit all applications.
• Lack of adjustable reset timeout period may restrict customization.

Working Principles

The ADM805LANZ operates by comparing the power supply voltage with a preset threshold. If the voltage drops below the threshold, the IC generates an active-low reset signal. This signal remains active until the voltage rises above the threshold or a manual reset is triggered.
