Essence

The essence of ADM706TARZ lies in its ability to monitor the supply voltage of a microcontroller and generate a reset signal when the voltage falls below a certain threshold.

Packaging/Quantity

ADM706TARZ is typically packaged in reels containing 2500 units per reel.

Specifications

• Supply Voltage Range: 1.2V to 5.5V
• Reset Threshold Accuracy: ±1.5%
• Reset Timeout Period: 140ms (min)
• Quiescent Current: 25μA (typ)
• Power-On Reset Delay: 100ms (typ)

Detailed Pin Configuration

ADM706TARZ has a total of 8 pins:

1. VCC: Supply voltage input
2. GND: Ground reference
3. RESET: Active-low reset output
4. MR: Manual reset input
5. VTH: Voltage threshold selection input
6. CT: Capacitor connection terminal for reset timeout adjustment
7. GND: Ground reference
8. VCC: Supply voltage input

Functional Features

1. Voltage Monitoring: ADM706TARZ continuously monitors the supply voltage.
2. Reset Generation: When the supply voltage falls below the set threshold, ADM706TARZ generates an active-low reset signal.
3. Manual Reset: The manual reset input allows for external control of the reset function.
4. Voltage Threshold Selection: The voltage threshold can be selected using the VTH pin.
5. Reset Timeout Adjustment: The reset timeout period can be adjusted using an external capacitor connected to the CT pin.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various microcontroller systems.
• Precision voltage threshold options provide flexibility in system design.
• Low power consumption helps conserve energy.
• Small package size saves board space.
• Wide operating temperature range ensures reliability in different environments.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer timeouts.
• Lack of built-in hysteresis may result in potential noise-related issues.

Working Principles

ADM706TARZ operates by comparing the supply voltage with the selected voltage threshold. If the supply voltage drops below the threshold, the reset output is activated. The reset remains active until the supply voltage rises above the threshold or a manual reset signal is received.
