MAXREFDES1171, Low-Power Fault Indicators Reference Design

MAXREFDES1171, Reference Design uses Maxim low-power chips for power grid fault indicators based on the low-power Arm Cortex-M4 processor. The MAXREFDES1171 is a high accuracy, low power, small and easily implanted design that can monitor the power status on the power grid line. Power grid coverage is widening in cities and the countryside, so power grid reliability and a short power-off time are important. The key requirements for a fault indicator are accuracy and very low power. One specification is that the unit must work for at least five years when in battery mode
