Detailed Pin Configuration

ADM6328-25ARTZ-R7 has three pins:

1. VDD: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin outputs an active-low reset signal when the monitored voltage falls below the threshold.

Functional Features

1. Voltage Monitoring: ADM6328-25ARTZ-R7 continuously monitors the voltage level and provides a reset signal when it drops below the specified threshold.
2. Power-On Reset: It includes a power-on reset delay circuit to ensure stable operation during power-up.
3. Manual Reset Input: The device can be manually reset by asserting a low signal on the RESET pin.
4. Watchdog Timer: ADM6328-25ARTZ-R7 incorporates a watchdog timer that resets the system if it fails to receive a periodic input within a specified time.
5. Small Package Size: The SOT-23-3 package allows for easy integration into space-constrained designs.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring with a precision of ±1.5%
• Low quiescent current consumption, minimizing power consumption in battery-powered applications
• Power-on reset delay ensures proper initialization of the system
• Manual reset input provides flexibility in system control
• Watchdog timer enhances system reliability

Disadvantages

• Limited reset timeout period may not be suitable for all applications requiring longer timeouts
• Only supports a single voltage threshold (2.5V)

Working Principles

ADM6328-25ARTZ-R7 operates by comparing the monitored voltage with the preset threshold voltage. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or an abnormal condition. The power-on reset delay ensures that the reset output remains inactive during power-up until the voltage stabilizes. The watchdog timer monitors the system's activity and generates a reset signal if no activity is detected within the specified time.

Detailed Application Field Plans
