2. C/ G type
Caution The above connection diagram and constants do not guarantee correct operation.
When the lithium-ion battery goes down to the overdischarge voltage, the built-in voltage detector powers
OFF the voltage regulator, and at the same time it transmits the RESET signal to the microcomputer. R
