Battery Management and Auxiliary Power Supply Options for E-Meters
Description
Smart electric meters are required to maintain normal operation for a short period of time after the electric grid fails. This reference design details methods by which designers can meet this requirement when using an advanced: smart meter MCU. Designers can use this design to evaluate options for battery management and auxiliary power supplies quickly and easily.
Features
- Two types of power sources for the auxiliary supply of the host MCU: independent regulator with super-cap back-up and (2) AAA batteries Separate power supply for Real-time Clock Automatic time capture of external events for tamper detection Automated or manual switching of power supply Automated power supply monitoring
Applications
- Electricity meter
- Power quality analyzer
- Power quality meter
Product Categories
- Arm-based microcontrollers
