Application Note
Current Consumption
reduce current consumption, please note following when executing program Turn (lbEN=1) only when detecting battery, turn (lbEN=0) immediately after detection. When entering SLEEP mode, Port input status input status, detect Port status first. Turn Pull-up Port=0; turn Pull-up Port=1 (Pull-up must always turned Port 1.0) When entering SLEEP mode, Port output status, Port should cleared When entering SLEEP mode detecting resistor, RF_EN must turned off. After completing above procedures, current consumption will less than SLEEP mode.
