Disadvantages: - Limited number of pins for additional functionalities - Not suitable for applications requiring precise voltage monitoring

Working Principles

The ADM6315-44D3ARTZRL operates by comparing the power supply voltage with a fixed threshold voltage. When the power supply voltage drops below the threshold, the IC generates a reset signal to the microprocessor. The reset signal remains active for a specific timeout period, allowing the system to stabilize before resuming normal operation.
