Pin Configuration

ADM6348-42ARTZ-R7 has three pins:

1. VDD: Supply voltage input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the voltage level.

Functional Features

• Voltage Monitoring: The ADM6348-42ARTZ-R7 continuously monitors the supply voltage and provides a reset signal when it falls below the specified threshold.
• Manual Reset Input: The device includes a manual reset input pin that allows an external signal to force a reset.
• Watchdog Timer: It incorporates a watchdog timer that can detect and reset the system if it becomes unresponsive.

Advantages and Disadvantages

Advantages

• Wide voltage range allows compatibility with various electronic circuits.
• Low quiescent current minimizes power consumption.
• Precision reset threshold ensures accurate monitoring.
• Small package size enables space-saving designs.
• RoHS compliance promotes environmental friendliness.

Disadvantages

• Limited reset threshold options may not suit all applications.
• Watchdog timer timeout period may not be adjustable, limiting flexibility in certain scenarios.

Working Principles

ADM6348-42ARTZ-R7 operates by comparing the supply voltage with the preset threshold. When the voltage drops below the threshold, the device generates a reset signal. The manual reset input allows an external signal to override the monitoring function. The watchdog timer continuously monitors the system's activity and resets it if necessary.

Application Field Plans

ADM6348-42ARTZ-R7 finds applications in various fields, including: 1. Power management systems 2. Battery-powered devices 3. Industrial control systems 4. Automotive electronics 5. Consumer electronics
