MAXREFDES1171: Low Power Fault Indicator

MAXREFDES1171 uses Maxim® low-power chip to implement grid fault indicator design, based on low-power Arm® Cortex®-M4 processor. MAXREFDES1171 is designed with high precision, low power consumption and small size, making it easy to transplant into the customer's terminal design and used to monitor the power supply status of power grid lines. As grid coverage continues to expand in cities and rural areas, the reliability of the grid and the maintenance of continuous power supply time are very important. The key requirements for the fault indicator are high-precision measurement and low power consumption, and it must maintain operation in battery-powered mode for at least 5 years.
