71M651X Operation with Batteries
要約:Some types of meters have batteries, mostly to support time-of-use functions. In these meters, the battery maintains the oscillator circuit and the real-time clock (RTC) when board power is not present. This application note describes the production sequence when using Teridian's 71M6511/71M6513/71M6515H, single- and 3-phase energy-metering ICs, in conjunction with a battery.
