17.2. 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) < 3.57V
The CPU detects this level and “Recharge battery” LED starts
flashing.
- Power Down
Battery voltage : V(Batt) < 3.3V
The output of RF IC (P-DOWN) becomes low level, then CPU stops
working to keep the data (CH number, ID Code, etc.)
