2. GND: Ground reference
3. MR: Manual reset input
4. RESET: Reset output

Functional Features

Voltage Monitoring

ADM1818-10AKS-RL7 continuously monitors the supply voltage and compares it to the preset threshold voltage. If the voltage drops below the threshold, the reset output is activated.

Reset Signal Generation

When the supply voltage falls below the threshold, the reset output is asserted, indicating that the system should be reset. The reset signal remains active until the voltage rises above the threshold and the timeout period elapses.

Manual Reset

The manual reset input (MR) allows for an external reset signal to override the voltage monitoring. When MR is pulled low, the reset output is immediately asserted, regardless of the supply voltage level.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system energy efficiency.
• Wide operating voltage range makes it compatible with various electronic devices.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring and reset functionality.

Disadvantages

• The reset timeout period may not be adjustable, limiting flexibility in certain applications.
• Lack of additional features such as hysteresis or adjustable thresholds may restrict its use in specific scenarios.

Working Principles

ADM1818-10AKS-RL7 operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage drops below the preset threshold, the reset output is activated, indicating that a reset is required. The reset signal remains active until the voltage rises above the threshold and the timeout period elapses.
