Manual shutdown

At any point in the charge cycle, the FP8103 can be put into shutdown mode by removing RPROG

or put the EN pin to the low-level voltage. This reduces the battery drain current to about 2uA and the

supply current to less than 55uA. A new charge cycle can be initiated by reconnecting the program

resistor.

Automatic Recharge

Once the charge cycle is terminated, the FP8103 continuously monitors the voltage on the BAT

pin using a comparator with a 1.8ms filter time (TRECHARGE). A charge cycle restarts when the battery

voltage falls below 4.15V (which corresponds to approximately 80% to 90% battery capacity).This

ensures that the battery is kept at or near a fully charged condition and eliminated the need for periodic

charge cycle initiations. CHRG output enters a strong pull-down state during recharge cycles.
