Package

ADM6321AY31ARJZ-R7 is packaged in a SOT-23-3 package, which is a small surface-mount package with three pins.

Essence

The essence of ADM6321AY31ARJZ-R7 lies in its ability to monitor voltage levels and provide a reset signal when the voltage falls below a certain threshold.

Packaging/Quantity

This product is typically available in reels or tubes, with a quantity of 3000 units per reel/tube.

Specifications

• Supply voltage range: 1.8V to 5.5V
• Operating temperature range: -40°C to +85°C
• Reset timeout period: 140ms (typical)
• Power-on reset delay: 20ms (typical)
• Output type: Active low push-pull

Detailed Pin Configuration

ADM6321AY31ARJZ-R7 has three pins:

1. VDD: Power supply input pin (+1.8V to +5.5V)
2. GND: Ground pin
3. RESET: Reset output pin (active low)

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the specified threshold.
• Provides a stable reset signal during power-up and power-down sequences.
• Low quiescent current consumption, making it suitable for battery-powered applications.
• Active low push-pull output ensures reliable reset signal transmission.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Accurate reset threshold ensures reliable operation.
• Small package size enables space-saving designs.
• Low quiescent current prolongs battery life in portable devices.

Disadvantages

• Reset timeout period may not be adjustable, limiting flexibility in certain applications.
• Limited availability of alternative models from other manufacturers.

Working Principles

ADM6321AY31ARJZ-R7 operates by continuously monitoring the supply voltage. When the voltage falls below the specified threshold, the reset output is activated, indicating a power failure or unstable voltage condition. The reset signal remains active until the voltage rises above the threshold and stabilizes.
