Power management
The STEVAL-IPE012V1 demonstration board is designed with board power consumption 4
VA.
The board supports two modes of operation:
1.
2.
Meter run mode
When mains power is on, the board operates in run mode. The board components are
powered using a capacitive supply with main power line as the source. In this mode, the
rechargeable battery is in charging mode based on the trickle charging technique.
Meter low power mode
When mains power goes down, the onboard microcontroller enters halt mode and metering
IC is off. In this mode, the microcontroller RTC is running and low, other peripherals are off.
In halt mode, the microcontroller is powered using BT1.
Therefore, push button SW3 is pressed in low power mode; BT2 supply connects to the
supply input of the microcontroller and IrDA section, and so, in button pressed condition,
BT2 is the main supply source.
The following metering parameters are logged in EEPROM memory for the current
month and last six months

Two duplicate entries of cumulative energy are stored with CRC-8 value for error
detection
10 bytes stored for calibration data at start of EEPROM including 3 bytes of CHV, CHP,
and CHS

Average PF and averaging count
Tamper entries; four types of tamper data storage is done: earth, reverse, neutral,
and case tamper. For each type of tamper, the number of tamper entries per
month is four.
Number of times cumulative energy overflows from 99999.9 (maximum display
precision).
