Detailed Pin Configuration

ADM6348-46ARTZ-R7 has three pins with the following functions:

1. VDD: Connect this pin to the positive supply voltage.
2. GND: Connect this pin to the ground.
3. RESET: This pin outputs a low signal when the monitored voltage drops below the specified threshold.

Functional Features

The functional features of ADM6348-46ARTZ-R7 include:

• Accurate voltage monitoring: It ensures that the voltage remains within the desired range.
• Power-on reset: It provides a stable reset signal during power-up.
• Low quiescent current: It consumes minimal power, making it suitable for battery-powered applications.
• Small package size: The SOT-23 package allows for space-efficient integration into circuit designs.

Advantages and Disadvantages

Advantages

• Precise voltage monitoring helps prevent damage to sensitive components.
• Low power consumption extends battery life in portable devices.
• Small package size enables compact circuit designs.

Disadvantages

• Lack of a watchdog timer limits its use in applications requiring a reset signal after a specific time interval.
• Limited voltage supervision range restricts its compatibility with certain circuits.

Working Principles

ADM6348-46ARTZ-R7 operates by continuously monitoring the input voltage. When the voltage drops below the specified threshold, the RESET pin outputs a low signal, indicating a power failure or an out-of-range condition. This signal can be used to trigger appropriate actions, such as shutting down the system or initiating a reset sequence.
