20.2. Battery Low / Power Down Detector

Circuit Operation:

“Battery Low” and “Power Down” are detected by RF IC which check the voltage from battery. Shortly, every detected blocks are inside of RF IC. The detected voltage is as follows;

∙Battery Low

Battery voltage : V(Batt) < 3.457V

The CPU detects this level and “Recharge battery” LED starts flashing.

∙Power Down

Battery voltage : V(Batt) < 3.0V

The output of RF IC (P-DOWN) becomes low level, then CPU stops working to keep the data (CH number, ID Code, etc.)
